I posted this is another forum and got bumped over, which makes sense. I see a lot of cameras online. What does everyone use primarily and why? Neximage? Svbony? ZWO? I’m not looking for any DSLR examples. Thinking, simple and good for people who are starting out and want to see and stack images. I’ve learned so much over the past week thanks to this board and YouTube.
Also, If you get a USB camera it means you have to have your laptop with you at all times In order to take shots, correct?
Purpose: The a moon and Planets
For the moon and planets, and your budget, I would recommend the ASI224MC. Cost is ~$250, but it might be a pain to find anything from China in stock right now.
You can sit by your scope with a laptop to run the camera, or just run it with a headless computer at the mount...due to bugs, that's what I'm doing right now. I'll just go outside to set up, then go back inside and remote into the mini-PC on the mount from a computer indoors. Keeps the bug bites down to only a dozen or so.
Don't forget a IR Blocking filter, the 224MC doesn't have one. Your images of the planets can seem hard to process (looks out of focus/not stacked properly) if you don't use one. This is because the IR light doesn't reach focus at the same point as the visible light does. I use both an IR blocking filter and a Baader Contrast Booster filter while imaging planets with this camera. The Contrast Booster isn't really designed for imaging, but it seems to work well even in my SN-4. Definitely need it with my achromat fracs.
I have the SVbony SV305, which uses the same imaging sensor as the ASI290, but I've yet to give it a serious run...I got it because it was dirt cheap and the guys in the EAA thread were getting good results with it...but I'm not doing EAA right now as I'm, chasing planets for AP with the 224...so I can't really say if it works great for planetary, although it SHOULD...but be advised it has only USB 2.0 (might limit you)
I also have the ASI290 which has USB 3.0 like the ASI224. You didn't say what your focal length was, but they have different sized pixels so it makes sense for you to choose your camera based on the focal length achievable in your scope. The guys in the planetary forum advise a
focal length (edit: focal ratio) 5-7 times your pixel size in micrometers...if you have a fast scope, just barlow it to get the focal length (Edit: Focal Ratio, not Focal Length...sorry for the confusion) you need based on the pixel size of whatever camera you get. Has been working great for me.
