Assembling my new ASI 6200MM with EFW and OAG
You gave a good walk-through (lose the USB atomiser) and can tell you've done some hard nights out, so mostly agree with your vid content. Carrying around that EAF assembled scares me. And no mention of packing & then stowing very wet scopes, gear & mounts, as I saw your dew shield. At -3 some nights, I use similar gloves to pack with, don't mind the wet but the ice, no. Cheers.
Great tips and very well done video. Thank you!
I do much of my imaging at home, despite light pollution. I do keep my telescope assembled to not only speed up set up time, but I don't have to shoot flats for every session and I also protect the threads too.
Some tripod, eh. More than 2K. Generally, looks very complicated and uncomfortable trips. Just buy land, and build remote observatory.
Nice rig! ❤
Brilliant ideas!! I especially love the bubble wrap - affordable and super effective. I haven’t tried it yet, but could an upside-down ice fishing tent work as a wind block? I really enjoy your videos - thanks so much!!
Great tip on the rubber gloves! Now I'm feeling a bit stupid, having taken my shoes off last time to unscrew stuck adapters 😅
Useful and simple ideas! Thank you so much
We have to buy a Tesla also? Elon perfectly use this video for the company :) Thank you for the video anyway.
I need to research the amperage draw from my setup - I have only run it on my Jackery 300 - EQ6-R Pro, ZWO cooled camera, heater, ASI AIR and an ASI EAF. I dropped from 99% into the 70s in an hour - when I lost my main target (I only had 1 or two images of my target before it went behind the trees), I need to see what the AMP draw on each of the items are to calculate how long it should run - or plug in the battery pack to the car/ car inverter to extend the usage. I do not think that I would go thru the trouble of running the setup for only 3 hours of pictures before the battery would die. This is a critical factor which I had not considered until August when I realized how much power my system was drawing. I may try to do the same setup with a different source for the heater and see if that helps.
Which camera and how many degrees were you cooling to?
Love your channel. So interesting and informative
Glad you enjoy it!
@@the_space_koala plus I love Switzerland so seeing the incredible views on some of your videos is a bonus. Best wishes from Ireland
Very good info.I have the ZWO AM5 mount and I like it very much!
That mount works super well!
Bubblewrap is a good tip. I have all my gear in cases too but when traveling with the family (wife + 2 kids) I needed to strip down everything. Thankfully we also have a Model Y which is extremely roomy and I confiscated the subtrunk for astro + 1 case in the regular trunk 😬 and the harmonic mounts are a blessing too.
I have blanket and pillows in the subtrunk 😁
Very practical tips. I am a dome-less amateur astronomer so I use semitransparent plastic-bags over the telescope to take flatfields. The only dome I have is a con-dome, way to small for a C14.
lol it took me a second
Thank you, good informations here :)
@@alexandreastronomy8022 oh I’m glad thanks!
What about the counter-weights? You're really straining your telescope mount if you don't use counter-weights to counter-balance your telescope. I always put the counter-weights on my mount first BEFORE I load my Celestron 11 inch HD scope on it.
strain wave gear mounts do not require counterweights - the motor is under no strain whatsoever
@@the_space_koala Wow! I really did not know this! No counter-weights required? I have a CGEM DX mount for my 11 inch and I have to use counter-weights. I will certainly be doing research on this type of mount. By the way, what's the weight of a mount like this one that you're using?
This one weighs about 9kg and can carry approx up to 30kg without a counterweight. It’s linked in the description
That’s how I mount my scopes in the observatory too. I use one of those observing chairs where you can adjust the seat up and down and I can get it right next to the pier.
that's real handy! I was thinking of an observing chair as well but at the end I went for something that takes up literally no space in my car :)
With a little trial and error, some thick aluminium plate and angle you could probably make a hook like attachment to go on those black clamps and over the red saddle mount to hang and capture the scope, initally as an extra safety. Later with tweaks and refinement you should eventually be able to just plonk the scope on and snug it up quickly and efficiently without the stool.
I'm not able to lift up the scope and aim it at the right place - it is too large, I don't even see the "other side"
Hi Luca, so nice to find your beautiful channel. I am considering buying an RST 300 harmonic mount, which I believe you have here, coupled with a carbon fibre supermount tripod. How do you find this set up? I was considering adding it to my RASA 11 as well as a Skywatcher 6inch refractor. I love the idea of a HD C14, but seeing this set up, the weight for me is a bit off putting. I would be a single observer too with no help. You manage it, but it looks a bit of a task and the strain on the motor initially to lift rather puts me off doing it that way. Like you I have alot of similar equipment so will really look forward to your videos helping me how to use it. I have an ASI air which is very useful. Best wishes Steve.
hey Steven! thank you. I find the rst300 amazing - it is my favorite mount. It is the only harmonic mount on the market currently that is able to handle such a payload without any issues. I wonder if for your RASA11 and the refractor even a smaller mount would be enough - of course that's up to you. The supermount is a godsend (I have both the Cyg42 and the Cyg48), it is just such high quality down to the last screw, it is absolutely worth it and I would never go back to one of those common carbon mounts unless the payload is very small
@@the_space_koala Hi Luca, So nice of you to reply. Your videos have already helped me a lot; especially on calibration frames. You have such a detailed, but clear way of explaining. I' m considering the RST300 over the RST135 as I originally had a Celestron Edge 11 inch. I was however considering an upgrade to Edge 14 inch later for planets. CYG54GRDLS was the tripod I was considering. I started life with a 3 inch age 12 and then graduated to a CPC 1100 but that was nightmare for weight as the OTA cannot be detached from the fork mount. I sold that eventually. Clear Skies for "baby Saturn" 💚
Wow, what a lecture! Thank you so much for the enlightenment regarding this subject. You provide much needed clarification.
Glad it was helpful! I think it takes a minute to wrap one's head around this concept after hearing "faster is better" everywhere, but I'm so happy my video could get this point across!
@@the_space_koala Thanks, I am so glad to find your channel, you are a great teacher. Have a great day.
C-14, eh? To mount it, even a little girl can do it? At the end looks way out of balance!
it is mostly balanced! you would be surprised by how heavy the mirror and especially the mirror cell is!
@@the_space_koala I would use a heavier table, it's scarry to watch you balancing that heavy OTA!
Thank you, for both the review & the self-scrutiny you went through. I've had ZWO stuff in shopping carts twice now, but abandoned the sale each time. My club has so many horror stories over warranty/ repair, shipping / customs drama - that I cannot pull the trigger. I like your work. Cheers.
thank you! I have a lot of ZWO stuff and I like it but I remain realistic and this one is just not it for me! I have also had issues with 2 different ZWO cameras already but the local retailer took care of it for me. I would never order one of these expensive cameras from overseas because I'm just not prepared to deal with any potential issues even if covered by warranty!
Very impressive!
Thank you!
Good technic...and impressive tripod A shame is so expensive.
I know, tell me about it! It's great but I wish it was more affordable.
Very good technique. Which harmonic mount do you have? Do you need to balance it for imaging at native focal length?
it is the rainbow astro rst300 (linked in the description). It is more or less balanced the way I show it here. With such a large weight that is all concentrated in the back a small change by adding a camera or dew shield is negligible so I don't actively balance
Thank you
This make my bones suffering it's better for observatory otherwise it may be damaged or the mount wear soon😊
it is not even remotely challenging for the mount :) I do wish for an obsy though
I agree with your comment that ZWO is going in the direction of improved portability of the astrophotography set up. And that’s a great idea! I have several ZWO products and love them all. I prefer the individual 2600, guide scope and the ASI air because it just gives me more options for whatever set up I’m going to build for the night. Keep up the great work.
I have the 2600 color duo, I switched to that because 95% I use the color camera on my RASA so it was just simple. I absolutely despise guide scopes so on all other scopes i use an OAG. Thank you for your kind words
You're a myth, five stars!
how nice, thank you for saying that
Good job finding a solution to a tough problem. A suggestion: perhaps a more stable platform would reduce the possibility of a disaster. I'm thinking one of those white plastic top tables that fold in the middle and the legs fold inside for easy carrying. I have a four foot model with legs that telescope and lock; the low position might be the ideal height for your task and the scope would easily slide into position without any possibility of tipping over. Also, it is much easier to lift with your legs than arms. A low stable platform to step up on would eliminate the need to lift with arms alone. The MGHH Folding Table 4FT, Plastic Table Height Adjustable Table for Picnic, Camping, Kitchen, Beach, Party, Outdoor Indoor, 47 x 24 x 29 Inch,White on Amazon is $25 and adjusts to 19", 24", or 29" and can hold 500 pounds. They also have a variety of stable platform type step stools or even those aerobic step platforms would be super stable and easy to step up on. You got me thinking how an old guy like me could handle a monster scope. Clear skies.
hey! thank you, all of these are valid ideas and I appreciate the suggestions, I may look into the step stool idea. The only thing is it's that many more things I have to bring around with me, pack/unpack everytime and even with this giant ass scope I'm trying to keep it as lean as possible :D
@@the_space_koala I’m thinking a permanent observatory, like a roll off, is in your future. ;)
may your prophecy be fulfilled :D
Good job on mounting it alone! But you have a lot of courage to put that beast on that mount without counterweights. If you unlock by mistake the clutch, it will be history
thank you! there is no clutch on harmonic mounts
Field mounting a C14 solo is a scary task for anyone. I think I held my breath until you had those saddle knobs secured. Good job! I'm guessing you had that mount near its maximum if you loaded up that scope for AP. You are a very interesting lady, keep it up, Michael
thank you very much! interestingly, this mount is nowhere near its limit with this beast. Well, if I were to load a deep sky setup, I would be nearing the limit without counterweight. Then again, I can push it a lot further by adding a counterweight, if I wanted to.
Very helpful, thank you!
Reminds me of when I mounted a cabinet to the wall in my bathroom by myself! I put it on top of an old table that was nearly tall enough, then added books and such to raise it a bit more. Got it level and screwed it to the wall.
work smarter not harder!
wow, so beautiful
Thank you! 😊
Focal ration does make a difference with respect to Spatial resolution! (not to be confused with angular resolution) Airy disk (spatial resolution) is directly proportional to focal ratio; this is the resolving limit for an optical system, any smaller detail is lost in the diffraction pattern presented on the sensor; width of disk ~= 2.44 *lambda*f/a; where lambda is frequency of incoming light, f is the focal length, and a is the aperture; f/a is the focal ratio;
I agree, I did briefly mention this at the end quoting faster instruments have a worse performance producing contrast at higher spatial frequencies. However, I believe this is something that could theoretically be recovered using deconvolution algorithms as long as you're at least critically sampled
@@the_space_koala Thank you, I understand.
Buy a Seestar s50 best telescope on the market 🎉
lol I have one
I think I held my breath through the entire video. Great technique! As I'm getting older, my scopes are getting heavier. This definitely gives me some ideas.
glad you find it useful! now, breathe..... :)
I actually have a 9.25 on order, but now I think I should have gone bigger...
are you thinking you definitely want to make your life harder? :D
@@the_space_koala Yes, life will be harder, but I'll have severe buyer's remorse if I don't get the biggest scope I can get :) Actually, though, I'm limited by my AM5 mount, so I think I need to stick with the 9.25 for now. That mount looks amazing.
that's a good choice. I have imaged with my C11 on my RST135 (which has the same motor as the AM5) but it's super sensitive to wind and it only worked well on a stable pier. So the C9.25 may be the sweet spot for you!
Nice work. A weird camera. Not for me - something I knew. But thanks for a good review and for confirming my thoughts Luca.
I agree - this is for a very specific demographic only!
🔭🌟👍💓
I am curious how you take flats on your 14 in. are you forced to use the T Shirt method at twilight? Thanks Bill
the t-shirt works but I also have a gigantic self-built flat panel (made of a pre-cut EL sheet ordered online and an opaque acrylic disc in front)
@@the_space_koala Thanks for the response. I would like to see plans / photos on how you did this, the light source you used. Thanks Bill
if you search for "EL Sheet" you can order pre-cut circles from Amazon or any Chinese website - you also have the option of ordering it already with the inverter attached which has a 12V input. For the acrylic I just custom ordered from a small Italian company called Plexishop. The important thing is order it more opaque than you think you'll need it - you can always expose your flats longer, you can't make them shorter if it's too bright :D
I would recommend not putting any pressure on the front corrector plate. So a larger surface area stool would be better if you need to do this method - or have the front cover fitted. Personally i would get a strap to hook onto the scope handles, and hang the scope around my neck like a massive medallion. Then attach the scope to the dovetail mount. You can stand on a small step if your mounting is too high, or simply adjust the length of the strap.
There’s no pressure on the plate whatsoever - it has a metallic cover that is sitting on an also metallic ring that protrudes like 5cm from the corrector! The strap around my neck idea sounds like a sure way to injure my back 😁 there’s just no way I’m strong enough for that!
@@the_space_koala yeah, there is a possibility of choking oneself with the strap too! 🙂
Come to think of it - i would build a shed observatory around the scope so i didn't have to lift it...
I'm a little guy and have been wanting to get a bigger scope but have been avoiding it because of not being able to mount it. This gives me hope :)
Glad it does - once you buy a big tube you’ll make it happen cause you can’t just leave it to collect dust in the corner 😁
@@the_space_koala Where did you get that little spacer looking attachment on the end of your rail?
@@ColecoJoe it came with my C14 that I bought used but I think you can buy it under the name "dovetail safety stop" or something similar
@@the_space_koala ahh thanks, i've been trying to word it in my searches :)

It has a metallic cap on the front
I bet that thing can see the accretion disk around Sag A* 😂😂
Yes I see the aliens waving at me on a regular basis!
Search for Motorcycle lift stand. The ones for motorcross bikes. They're only cheap. They are lower than your stool but with a lever, lift a lot higher. You would need to fix a board to the top of it, similar in size to your scope. Might work better. Sweet scope BTW ! wow.
I looked into those but they weigh as much as the scope itself 😁
@@the_space_koala Nooo, they're small. Lift with one hand, easy.
@@Carl-ro1ub do you have a model for me to check out?
@@the_space_koala I loaded a link but it must have been removed 😞 Look for ones specific to motorcross bikes or trials bikes. Its a small rectangular platform that is raised by a manual lever at one side. They're a one person lift easy.
Well done and I love that idea, so youre not putting yhe scope on the mount, youre pitting the mount on the scope 😊
In fact I’m “mounting” my scope 😁😁
That is an amazing mount to torque up that 50lb tube. Impressive idea, and thanks for the inspiration.
