I am thinking about buying an Orion XT8 with GoTo system.
I know people have done simple EAA on Alt Az mounts with telescopes like the Skywatcher 200P Dobsodian or the Celestron SE8, which have GoTo tracking. The key is doing multiple stacking of exposures limited to 10 seconds.
This way one would be able to image several deep sky objects like nebula and galaxies. Though the limitation is rotation of field which limits exposure and a mount not suited for perfect EAA or AP.
Are there anyone here doing EAA or AP with this telescope, or a similar one?
I assume the tracking allows to keep the object on the field for a sufficient time for short exposures.
One concern is that the weight of the sensor may cause small movements and the tube to move slightly down during imaging.
Finally, because I am a true beginner! Can I do stacking of pics taken on different days or do I need to do them all at same time? Do I need to upload each frame to the computer right away during observation or can I do it later from the comfort of home?
My idea is buying the XT8g, a focal reducer (not sure if its possible for focusing), a simple EAA sensor (or even in the mid term a simple camera), and start the hobby, of which I have no experience whatsoever/
I owned a 60mm refractor for 15 years, so my intentions is mainly visual of DSOs, by going for a much larger aperture (the 8" satisfies my cravings) and introducing myself to EAA by ocasionally imaging some nebula and galaxies. I await advice!
