I want to improve planetary photos and I'm going to buy a few things, including a ZWO camera. I tried Jupiter for the first time a few days ago with my APSC DSLR camera (see other thread if interested).
I read this very good article https://agenaastro.c...yers-guide.html
A few things are still confusing me...
For example, looking at the ASI178MC and ASI183MC. The article marks the former as best for planetary and the second as best for DS and ok for planetary. Both have 2.4 pixels. They have approx 6MP and 20MP respectively. The sensor of the former is obviously smaller. Using a x2 barlow on the latter gives roughly the same frame. They have 60FPS and 19FPS at max resolution respectively. The ASI183 specs list lower resolutions at faster FPS, but I'm not sure if this is binning or cropping.
At max resolution on both, would 60FPS vs 19FPS make a very significant difference? If I understand, pixels on target would be the same. The 183 would just have a lot more sky around it (waste basically).
Some of the advantages of a camera like the ASI183 could come later, when I try some DS objects or anything that would gain from the higher resolution and larger sensor.
I'm trying to understand if there are disadvantages that I'm missing for using the ASI183 and not the ASI178, ignoring the higher price and the 2" vs. 1.25" mounts.
Maybe the ASI183 would just give the same results, so the ASI178 would be better, and when I decide to try DSO later, I should get a camera that would be better for that. Better than the ASI183, or my ASPC and FF DSLRs?
I'm using these models as examples that I think best illustrate what I'm trying to figure out.
FWIW my telescope is a Meade SCT 8" 2000mm.
