Untill now I have been doing just visual observing with my 150mm f5 newtonian, mostly from my city flat balcony. I have a motorized non-goto mount which tracks reasonably well. I do star-hopping through a 25mm eyepiece (about 2º FOV) using Uranometria, becuase and I find it more interesting and entertaining. The thing is I really want to see a bit more of the DSOs. So I became quite thrilled when I found out about EAA...
I have no expericence with imaging. I have been considering using a guidescope with a camera on my telescope as a starting point. You know, star-hop like always and then taking a couple of tens of short sub-exposures just to see a bit more detail (honestly, apart form the brightest DSOs, I usually dont see much from my light-polluted area). This way I can start to learn the software and maybe upgrade later. BTW I have seen some EAA images done with a 50mm guidescope here and I was quite impressed!
I was thinking about the Evoguide 50ED + ZWO ASI 224 colour camera. Thish should give me about 1º x 0,9º FOV so when I have centered the desired area in my eyepiece, the object should fall more or less in the camera field. Running some simulations on Stellarium with this FOV, I can even starhop on my computer screen alone. How well dou you think this setup will perform? I guess since its an APO refractor, it should be better than the usual guidescopes and there should be little CA. Will I be able to achieve focus? Will I need some other accessories? Also, the SharpCap software can be used for polar alignment and a 1º-2,5º FOV is recommended for having enough stars, soo it seems that I can use it for this purpose as well, right?
Thanks, I will really appreciate any advice! Take care!
