@@KrishnaKumar-wj6jt the bigger the aperture the better details you will note specially from faint objects. That's a fact. But you can have decent results even with a 8". To this camera i recommend you to buy a reducer and an IR/UV cut filter. It will work much better specially with that filter.
Hello Tiago, I'm a new subscriber. I have enjoyed your videos and looking forward to learning about EAA. I own a 12" dobsonian telescope and want to learn more about EAA. I've learned a lot from you already. Looks like fun. Looking forward to your upcoming videos. Thanks Ernest
Thanks For This Video!! I have Dipped My toes To EAA imaging! Since Doing guided Long Exposure Astrophotography is Much More Expensive, I think This Is A Great Starting Point For Folks who are on Budget Like Me. I have the ZWO ASI 224mc and A 6 inch Newt on an Alt az Goto Mount, which Is My imaging Rig! Very Detailed Video!! Thanks For Sharing! Keep it up Clear Skies!
No. With ZWO Asi224MC was much harder but was the first live stack i've done. It's a tiny sensor and very hard to get in but i did it. The 1st image i saw was with this settings below. Note that an IR cut filter and an inexpensive 0.5x reducer near the sensor will help you a lot with that camera: NGC 2438 - Planetary nebula 12" f/5 GSO Dobsonian Geoptik Eartha Equatorial Platform ZWO ASI224MC Baader IR/UV cut L-filter TS 0.5x Reducer spaced to 0.7x 117 frames Gain=500 Exposure=1s
If one has budget to buy only one camera,just planning to start EAA,which (zwo 224, zwo385, zwo294 or any other) one would you suggest and why? Thanks...
I would strongly suggest the ZWO ASI294MC. It has a larger field of view, thus will frame more stars needed for the EAA live stacking. Make everything much easier and if you want to frame a little object you can reduce the display or even use a barlow. I have the uncooled version which is enough for EAA. In this video i've uploaded yesterday you can see my last images from EAA sessions with the ZWO294 ua-cam.com/video/Gc2CfBHfRKM/v-deo.html
Please advise,whether a single axis ,only RA, equatorial platform sufficient for EAA or a dual axis must. I have recently bought an Orion 8xti dob... Thanks.
Thanks for your tutorial, Tiago. I would ask you if it's possible to enlarge picture on sharpcap before saving it on laptop and eventually how can i do it. Thanks
It saves full picture then you crop. To save cropped you use the ROI-Region Of Interest. If you don't know, just ask me during a live stream, i show you
Another nice video, thanks.I have an 8" pushto dob but am planning to use a 114mm F4 Orion imaging newt and a C90 Mak with a ZWO ASI224 camera. These will be used on a couple of Alt/Az Ceslestron tracking mounts (Sky Prodigy and 4SE). Do you think this will give decent results?
@@DobsonianPower Thank you sir, I already own a 2x and a 3x barlow, would one or both of these enable the 114mm newt and my ZWO cam to image the moon and planets? I have on order a Dwarf2 EAA camera and will use it together with the ZWO 224 and the smaller Optical tubes...plenty for a beginner...
Nice images and setup! I'm using a 10" DOB with the ASI294MC Pro but I'm struggling to get images to come in focus. When using the DOB visually I have no problem getting stars in focus. I'm obviously missing something. Are you using anything other than the comma corrector (e.g. focal reducer) with your setup?
No but my set up is all tuned. Why can't you? What happen? You don't have enough backfocus? Do the stars get bigger or smaller when you turn the focuser IN?
Yes. Short exposures and you have to follow the object manually, doing with your hands what should be made by the equatorial platform. I never did it but there is a french forum where some guys do it a lot. Go there and search. At the main page you can click on translation to english and everything will be in english. www.astronomie-va.com/forum/index.php
I'm the new guy asking you so many questions, and I just found this video. While it's cold outside (near zero fahrenheit at night), I continue to research. My question pertaining to this video is about short exposures for EAA. I agree totally with your introduction and the possibilities of EAA for simply better viewing. With the "Align Frames", is it possible to get a few short one or two seconds photos and stack them for simply better live viewing (and color) without tracking? I understand that targets are going to move across the frame with long exposure times, and stars will image as streaks. In your experience, would that be a problem with one (or two) second exposures taken one second apart or so, or would I be wasting time trying? I looked at equatorial platforms, and I'm new at all of this, so not going to make a multi-thousand $ investment quite yet. I'll likely purchase a larger (12inch) Dobsonian before investing in a platform. Anyway, any input will be appreciated.
We can do that but with planets, moon and planetary nebulae because we don't live stack. We take thousands of exposures less than 1 second even without tracking. In theory is possible, you would have to manually adjust each frame the telescope but it's to suffer a lot and not to enjoy so i would not do it. If you're going to buy a new dob you can also buy one with goto and do it all.
Hello Tiago, I really enjoyed your video on EAA. It made me think about tracking the image and how important that is to get the best possible image. Looks like the equatorial platform plays an important part in getting the best image. If that is not right, then the image quality will be affected. What should I be looking for when selecting a platform? I've seen your video on the Geoptik Equitorial Platform but are there others of equal quality or better? Looking forward to your response. Thank You for sharing your knowledge, experience and expertise? Ernest @~ Keep it simple ~ Astronomy
Sir,any advice regarding camera QHY462 and ZWO 462 for EAA... is any of these midway between zwo 224 and zwo 294. In my country zwo462 is approx 300USD & QHY462 is approx 400USD... Still trying to find one camera which can get both planets and DSOs, atleast the brighter ones and also trying to get one with which it's easy to accquire targets.. Thanks.
Buying the 462 will not improve much more than the 224. And is too sensitive to infrared so you really will need to buy also an IR cut filter. It is a little bit better than the 224. Both good for planets and small objects astrophotography. You buy one and later you will feel the same need for a better camera for EAA. I strongly reccomend you to put the money on a 294 because it's good for everything. And with the right barlow combination is also very good for planets. And for EAA is the best in my opinion. It's more expensive but you will not need to upgrade, you'll be happy. If you can't really do it, you will be fine with the 462 but sooner or later you will buy another camera as i did and bought the 294. I still use the 224 for allsky and planets but i could use my 294 also for that but i would need to buy an allsky lens and the 224 has already one. Hope it help you to decide.
@@DobsonianPower Definitely this will help me decide... It seems that there are only two options.. 1)If budget is constrained then I should go with zwo224 with being ready to latter on moving to zwo294. 2)Save n go directly with zwo294.. Thanks.
@@drrdhc there are more options but at the end you will upgrade if you want DSO's and have a good camera for that. Many people sell their old camera but i still use my 224 so i didn't sell it.
I do it with sharpcap and live stacking, and use snapshot as kn the screen. Have used exposures over 30 secs on MY SCT 9.25, have a Skywatcher EQ6-R PRO mount. Have a .63x reducer. When I take a snapshot, I will enhance it slightly with GIMP. I got a QHY163C better cameras than zwo, and mine has a wide field and cooled camera, a big advantage. You can use narrowband filters for EAA also. Vusual for me now is a thing of the past. Unless your using a goto dob electronically tracking stars not ideal. A goto if far superior. With goto and EQ mount you have far less exposure times. I can go 2, or 3 min exposures if I need, with a motor driven system severally limits exposure and detail.
@@DobsonianPower for me visual is dead, only basically seeing fuzzy shades of grey, EAA brings them out. Used to do visual until recently until I started EAA, no eyepieces go in my telescope a cooled Camera with EAA dont even ever need darks, cooling keeps noise to a mini and use my camera to minus 20 degrees C
@@DobsonianPower I have used SharpCap about 50 times and never realized this setting!! Will use it next time! Are you using the free version or the premium version of SharpCap? Great pictures listed by you in the EAA images on CN Forum too.
That’s a great M51 image Tiago. I seem to have issues with live stacking on SharpCap. I often get a warning “not enough stars to align” and it won’t run. This is even with 10 stars selected. Any ideas on my issue? Scope is a Celestron Evo 8 EdgeHD on its standard fork Alt/Az mount.
That's the bigger obstacle to do EAA with sharpcap,: “not enough stars to align”. Could have different sources. In the video i show my settings for people to copy because it's one of the main sources of the problem but other can apply like bad sky seeing or transparency, not focused camera, etc. Once you solve that you're done opening the EAA door.
Hello Martyn, you are on SharpCap? If "yes", use the "digital" booster : x4 or x8 (near the place where you can indicate 10 stars, of what mini or maxi size, and so on)... Move also the others buttons and you will find the moment when your C8 will stack again. At this moment, don"t touch anything anymore :-)))
@@delphys75 Thanks! Yes, I’ll try this and play more with the settings until it stacks. Part of my problem is the small FOV so sometimes there aren’t many stars.
The digital booster may help and does not affect the image. The new version will have a different setting, the stars sensitivity, from 0 to 100 and easier to manage. For now is on the beta version testing. Also a focal reducer may help.
I want to get into EAA observing. I have the money to buy excellent equipment. Wouldn’t I be better off with a 12” go to dob so I can be inside the house and observe in comfort and not have to repeatedly go outside to adjust the scope. I would also have electronically controlled focuser. What are your thoughts ? Thanks for your help 😉
The answer is simple, YES. If going outside is uncomfortable to you, you should get a goto. I like to go outside and that's how i learn the sky but my winters are soft, so it's all about the situation and perspective.
@@DobsonianPower Thanks for your reply. I also go outside but getting older and to be inside with my laptop and EAA in the ice cold winter months and extremely hot summer months with insects it is much nicer to be inside my conservatory wired up to the scope. Nice temps no problem 😉
