      With the zwo 224 you have a small field of view so it's much harder but it's possible. In this video if you jump to the end you can see a lot of pictures i took with the zwo 224: ua-cam.com/video/3o_K8jwyIVs/v-deo.html

      @@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.

      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:

    Thanks...

    • @DobsonianPower
      @DobsonianPower  3 роки тому +1

      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.

    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.

    • @DobsonianPower
      @DobsonianPower  Рік тому +1

      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.

    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.

    • @DobsonianPower
      @DobsonianPower  3 роки тому +1

      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.

    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.
