Just wow....I was always told that this type of scope was only for visual use but these photos are really really good.
Took your advice and we brought a Baader contrast filter for our ST150. Boy what a difference, 15 years of "Christmas lights fringing" gone over night. The wife and I got so used to the fringing and were skeptical about the capability of filters, but we were blown over how this one got rid of about 95% of the nuisance. Thanks for the tips and keep them coming. What we like is you giving advice on how to keep costs down and making the joys of the universe reachable to the less wealthy - exactly what your video here was all about. Brill.
Thank you Rob for sharing your experiences with the ST150, Yep I never launch a video, if I knew it wasn't going to work. I always make sure my video content is true to my viewers and subscribers. There too many Astro channels making false claims, just for for views and subs!! That Baader contrast filter is defo the best buy for any Archromat, now you can take long exposure of deepsky objects, as long you can cope with the slight yellow cast in your images, as long the stars are not bloated with fringing, the filter will do an amazing job. Again Achromat can be used for imaging and totally true, that you do not need spend a ton of money on ED or APO Refractors to achieve decent images!! Remember the EQ mount with at least on RA tracking motor and the mount is Polar aligned correctly will be the biggest factor in order to achieve great viewing and long exposure Astrophotography!! Enjoy your new scope, and look forward to another MP ASTRO video, coming very soon!! Wish you Rob and your wife CLEAR SKIES!!
Thank you barton for Answering my question on the difference between the s t eighty and the skywatcher eighty, I have been enjoying your channel for quite a few days now.Thank you very much for all your information on how to improve the telescopes that we have.
No worries
Fantastic scope. Love mine. It’s such a great entry scope that later easily becomes a great guidescope. I love what you’ve done with yours.
Couldn't agree more Garnett!
Great mods and wonderful photos, Martin! Thanks for posting this video and all your hard work that goes into in your work. I really enjoyed watching it, as always.
Many thanks! Look to another video coming soon!!!
Another option for the drawtube light leak is to make a mask to slide over the drawtube inside the focuser. Draw the outline of the focuser housing and the centered drawtube onto a piece of black craft stock(can make one too using any craft paper and spray paint it flat black or flock it). Cut out to fit snug on the drawtube and enough clearance to be pulled toward the back of the housing. Fit it down over the drawtube from the inside down into the housing. Now back out the focus tube backside and it should move the mask to the maximum outward draw. Alternate methods include creating a thin rubber mat boot to slide over the tube like the shifter gear lever in a manual car. Lots of ways to approach this!
Also, don't forget you can flock or paint that focus tube taking into account the rail and the bearings that ride on the tube.
Awesome new tips there, thank you for your input in this Super tune video!! Let's share the ideas to help others!! This is what Astronomy is all about!!!
I'm planning on getting a short Eighty from orion soon, And I plan on tuning it up, So thank you.
Good luck 💯 Michael 🍀🍀🍀 You won't be disappointed!!
i like the st80 & own it plus the 102 ST both have a place in this hobby cheers
Good afternoon Martin. Looking forward to this one.
Yep this one IS THE REAL DEAL!!! 😎😎😎😎
As always, thanks for sharing your ideas. Another great video!
Thanks for watching!
Great video and excellent image processing .
A good instructional video and thanks. Your setup is superb
There will be another one coming soon with another budget telescope
Great!
really appreciate the video - i took mine apart some years ago and forgot which order to put the optical elements back into the tube. I''m now going to go re-visit this scope as it just sat collecting dust-stars on the shelf. I've always wondered how it will perform with a decent astro camera and narrowband filters - time to try.. Cheers and thanks Martin for the time you took to produce and explain the scope in detail. - Mark
Right on! I think with the Narrowband filters and decent camera, the ST80 will excel in image quality. With Narrowband imaging the chromatic aberration will not show up!!! The F5 seems to be perfect for imaging as well with decent field of view. I wish all EDs and APO telescopes are made at F5 not the usual F7 and F6 you see and you have to buy a focal reducer to just toget F ratio down which sometimes you can't get even close to F5.
Impressive results 👍
Thank you! Cheers!
This is my most travelled scope Martin. Have the tabletop skywatcher version with a plastic focuser. Would never sell it. Mine has a chrome focus tube but didn't like me darkening it with a sharpie pen. Had to strip and polish with Mr sheen.
Similar to my Mak 127, I would never sell it!! Thank you watching Vic, Good luck on the 102 rebuild Vic!!!
I made 3D printed 1:5 planetary gearbox for standard ST80 focuser.
We (wife and I) have a ST150 and AZ-EQ6 mount. Also recently purchased a CANON 600D. I shall astro modify it myself. Then we shall implement your supertune.
We will have to switch off the gas boiler for a month and the money saved will pay for the Baader filter. Thanks for the brill and really informative video.
Defo try the super tune, that huge 150mm aperture will be outstanding for the light grasp!! the Baader filter will help massively with that scope!!
@@MPAstro Martin we (wife and I) need some help. We are new to imaging and DSLR. Last night, using our ST150 and Canon 600D, we took 50 shots of andromeda, ISO400, 2 min exposures. A single 2 min shot looked similar to your single 2 min shot. However, we ran the 50 shots through DSS the final image looked the same as the single 2 min image again similar to your single shot clip. WE are baffled why we do not see the elliptical galaxy just the central round core? Any ideas why? Also, with your Jupiter video what shutter speed did you use? Thanks
The ST150 is a large aperture telescope, so the field of view is smaller, compared to the ST80 which as a wider field, hence your only seeing the central core, A focal reducer will help a little but it's still not enough, Have you tried Astronomy tools Field of View app, it's a great app and will help you determine what FOV you will get with the ST150. Here is the link to the app: astronomy.tools/calculators/field_of_view/
@@MPAstro Yes, you are right, using the FOV tool I can only see the centre of galaxy. Up to know I have only done visual observations. I am in my seventies and the ST150 is becoming a bit of a physical challenge. After watching your video, I plan to sell it and get a more manageable ST80.
Excellent video mate. You've definitely sold me on the Baader filter. I have a Skywatcher ST120 with an Altair lightwave premium dielectric diagonal. Have a T-ring but not with a filter thread so unsure where I'd place it while I guess it will have to be a 2 inch version.
Here's a thing though: I recently saw a video showing how the blue fringing can be eliminated in one of the photo processing suites (seems Photoshops and others can do it). Perhaps the filter would just make it so much easier in post processing however plus, when it comes to visual, by the look of it, that yellow cast is nothing much to bother about anyhow because we look for discerning detail in objects rather than just the overall colour. That's why we have coloured filters in the first place. Also, it makes me laugh thinking about 'false colour' or a little fringing when most astrophotographers use their LRGB filters on mono cameras and present photos in the end which don't even honestly represent the true colours of many DSOs. They're basically 'light painting'.
Thanks for watching Mark, there is a way to remove colour fringing on Photoshop, I think by adjusting the blue channel on the image, though this filter will reduce the effect alot, it is defo worth the cash and save alot of hassle in the process. Lol being a LRGB mono user myself, I totally agree with you there, you are light painting, especially when you Narrowband an image!!
@@MPAstro Still haven't invested in the Contrast Booster yet Martin (expensive and hard to find too) but, meanwhile, have you compared it at all to the Baader 495 longpass yellow filter? I've read a lot on that recently too and the word is it eliminates CA too. I'm now scratching my head as to which would/could be better? Crap weather recently huh?
Will the same trick work with Explore scientific ar102 refractor ?
Btw can you give the stacked data I wanna try to process
I got a ST80 for 5£ on a flee marked. Like you I was astonished by how good the telescope is. Have you considered using a monochrome camera with RGB or HA, S2, O3 , as it would nullity the shortcomings of the achromat, like chromatic aberration?
Already looking into a mono camera, Archomat telescopes do not get effected in Narrowband, and H-Alpha for solar imaging.
We just got our youngest the Celestron Travelsope 80 and I'm looking for upgrades and mods. I'm glad I fund this vid.
GO FOR IT!! You know it makes sense!!
@@MPAstro Lol, I just got myself a Svbony SV48P so I can have the cool 2 inch focuser on a grab and go of my own. Now I won't be tempted to add one onto my daughter's travelscope (we're still going to flock her scope etc. It does make sense.)
The GSO focuser is on its way.
@@FatherTedCrilly Awesome News!!! let's us know if the GSO focuser fits OK
@@MPAstro The GSO unit arrived this afternoon. Installation was a breeze. The unit fit PERFECTLY and was very snug. I reused the 3 original screws. The scope weighs 1583g or about 3.8lbs now with the focuser and a red dot finder added.
There are some differences in coatings. Orion Short Tube 80 is multicoated, the ST80 is fully coated and the CT80 is coated. I would suspect Celestron and Skywatcher do the same.
One problem with this scope is the tilting. See if you can address that possibly
Martin. Some advice please, I use Celestron astronomical binoculars, but how do I stop dew forming with large binoculars???
Sorry John for the delay, been working late. Yes you make dew shields out of cardboard and wrap around the objective lens, you minimse the dew forming on the lenses that way. Or you and fit dew band heaters and with a dew controller, you can power a 12v supply to heat up the objective lenses and stop dew completely.
Hello. Martin. Thank you both for your time, and also advice. Many regards. John
Sorry that i'm late to the Martin MP Astro Party!!
Not worry, there will be another live next month!!
Hi Martin, Thank you very much for your videos in special this one. I recently bought a Celestron Travel Scope 80 )second hand on ebay) and I had read too much bad and good information on the internet and I and confused. I just want to try to improve as much I can and you video will help me alot. Please, could you help me which eyepieces did you use for you pictures. I have only 10mm, 20mm and 3mm Barlow? I just started now using a telescope.Thank you very much for your help amazing job.
Very nice find!! I would suggest to look into some of these eyepieces, they are cheap but a very good quality, I think 12.5mm and 15mm would best all round for many objects and look at a 2x Barlow lens, has your 3x barlow is tad too powerful for your scope. Here is the link from FLO www.firstlightoptics.com/astro-essentials-eyepieces/astro-essentials-super-plossl-eyepiece.html
@@MPAstro Thank you very much. Please, keep making videos like this. This is very inspirational for beginners and people that have started in astrophotography. I would like to make a picture from Orion and Andromeda with my Celestron Travel Scope 80 🙏 like you 😁
Believe me Ivan, you'll will get those awesome images!! Then you'll be hooked into Hobby!!
Justing looking at the specs of the Celestron 80, and it seems you have travel tripod?? If you want to take Astro photos of Nebulae and galaxies, you going to need on Equatorial mount with at least RA tracking motor, take longer exposures?? Have you got such mount??
A quick question, Is the sky watcher eighty, Add the shortcut to 80 identical telescopes or Mike.The skywatcher eighty have a edge over the short tube.
The difference is the focal length, I'm guessing that 80mm is longer focal length than the ST80. which means the 80mm will be a much slower telescope than ST80.
Musou black for blackening the tube and absorb the 99.9 porcent of light
Started of my astrophotography journey with one of these 👍🏼 reyt scope for the money 👍🏼👍🏼
Certainly is a great scope for the money, I only wished it had a 2" format focuser
@@MPAstro would bump up the price accordingly tho eh 😕👍🏼 dream upgrade to my ST would be a crayford beast 👍🏼 I’ve got a 72ed now but would love to get my ST and see just how ‘better’ the ‘Ed’ glass actually is 👍🏼
I don't know that much, but I do have a ST80
Suppose I want to convert it to a 2 inch diagonal and eyepiece. What product would you recommend
Before you can use 2" format stuff, first you need to convert the focuser, here is part 2 of the ST80 super tune!! This might help you!! ua-cam.com/video/8q9EmDuoH3Y/v-deo.html
@@MPAstro I was hoping for an adapter that's a little more than I would wanna spend on this scope
Real shame they didn’t do much with this mount. I’ve wanted to buy one for a long time but they’re not sold in the US in any capacity
Totally agree, this Avant EQ mount is miles better than the standard Skywatcher EQ-1, which is such a terrible mount and yet Skywatcher continue to sell this old and outdated EQ mount, the RA axis motor drive upgrade for the EQ-1 is also rubbish and with no ST-4 guide connection. There is the Star Quest mount which is similar to the Avant EQ mount, but you have to buy it with the telescope and the RA Motor drive is sold serperately.
Star Quest mount with 102mm Refractor: www.firstlightoptics.com/beginner-telescopes/sky-watcher-starquest-102r-f49-achromatic-refractor-telescope.html
Sky-Watcher RA Motor Drive for Starquest and AZ-EQ Avant Mounts: www.firstlightoptics.com/sky-watcher-starquest/sky-watcher-ra-motor-drive-for-starquest-and-az-eq-avant-mounts.html
@@MPAstro I love making grab n go setups and this az-eq mount fits the bill in every way. Considered importing a mount + telescope and selling everything except the core of the mount but I haven’t done that just yet
I do see alot of the Skywatcher Star Adventurer mounts for sale on the secondhand market, but these mounts are so ovely priced and you need a very good tripod, which are hard to find which is suitable for the Star Adventurer. And GTI mount which is the latest one, looks great, but there is no stock left and again stupid prices, where EQ-3 and eq-35 are reasonably priced and already available. AZ-EQ Advant is defo a good mount, it was the worst choice for Skywatcher to discontinue it's production, this mount should have replaced the EQ-1 mount that's for sure.
Hello I was just wondering what dovetail bar I should buy for my skywatcher st80 to make sure I can balence it on a skywatcher star adventurer gti?
Any vixen dovetail will fit the ST80 not a problem, I think a 250mm long dovetail will do the trick for the SA GTI.
Thankyou very much for you response but one more thing, should I get the medium or large of the one in your description or are there any other dovetails that are better?
Get the large one Miles. Yes it will stick out abit and may look weird and will dwarf the main tube abit. But with a longer bar you will be able to make alot of adjustment on the balancing especially when you connect a DSLR camera at the focuser end. Ideally you want as much of the DSLR camera raised in such a way that bottom end does not collide when the DEC axis and RA axis hit either the tripod leg or the base, while you can still get a perfect balance, though it's going to take some practice to achieve this, so expect to do alot of tightening and untightening of screws and moving stuff about in order to achieve this!!
What adapter is that on the end of the focuser tube? Been looking for a replacement. Thanks.
It's 2" to 1.25" Eyepiece adapter
@@MPAstro The one here at 19:55? Just wanted to be sure. Thank you. I need something that has threads which will screw directly onto the focuser tube
@@mrtransistor6173 that is the standard 1.25" focuser, the threaded part is a T2 thread where you can attach a DSLR t ring
@@MPAstro Thank you so much! I'm quite new to all this, so a lot of learning.
@@mrtransistor6173 yep it's better to start learning and use basic equipment. Don't be those people who just use smart tech and smart telescopes, cheating their way, and just doing the lazy way of Astronomy and using AI to process images for them. Point taken it's great technology don't get me wrong, but you learn nothing from it. Have a purpose, have a goal, have a real sense of achievement and enjoy Astronomy the way it should be done!!!
I don't see any video 🙁
Yeh... you get a blue halo for free and pay through the nose for a yellow one
It's a good enough video but you really don't take any time to explain WHY each mod improves the scope before you do them.
