Pretty self explanatory.  What cameras would people suggest for a first planetary camera?  A few options would be nice due to the supply issues.  Please try to keep them under $300, unless you can give me a really compelling reason to go higher.

Anything based on the imx462 sensor, such as https://astronomy-im...t/asi462mccolor

The ZWO ASI224 color cam is going for only $199 I think. You need to add a UV/IR cut filter, but it works very well at f/20 with an SCT and a 2X barlow.

After some research, I am leaning towards the ZWO ASI462MC.  It will be going on a 10 inch 1200 mm f/4.7 scope.

I would also suggest the ASI224MC, however the ASI485MC with its larger sensor and similar characteristics would be a magnificant first camera (but is $100 over budget :().

Whichever camera you decide on, don't forget to factor in an IR-cut filter (mandatory) and 3x barlow lens so you are able to capture at around 5x the pixel size of the camera.

The budget is flexible.  My worry about this is I thought FPS is very important for planetary.  Granted the MP is much higher so not sure what the comparable FPS is when you cut the capture resolution down.

 

So the plan would be either the AS1462MC or the ASI485MC paired with the ZWO IR cut filter and would likely just grab the Tele Vue 1.25" 3x Barlow.

 

I do already have The Baader 2.25 Barlow.  Is that too far of for the pixel match?

The 485 tops out at 150fps with a smaller ROI. If you're going to chase higher frame rates you'll need a different camera. Personally I find the 485 is a much better sensor for colour imaging than the 462 was and is a much larger sensor and the maximum frame rate is far less important, but people may prioritise frame rate over colour sensitivity and accuracy (see the numerous threads popping up comparing frame rates now since I confused the issue by saying I only ever use 30fps). Note, I have both, and have largely stopped using the 462 for colour imaging.

This could still be usable with a spacer or ADC between it and the camera. With a 2.9um sensor you need approximately F15 for optimal sampling, and if you put a little bit of extra space behind the 2.25 barlow it will increase its magnification further to effectively make it 3x. Make it 1/3 longer than it currently is.

Any idea why that is? I would have thought the max framerate was determined by USB throughput rates, the USBTraffic setting in Firecapture, hard drive speed, that sort of thing.

I'm still thinking first draft driver issues rather than an intrinsic design limitation, much like the inbuilt offset I'm dealing with.

There are differing opinions on whether a really high FPS makes a positive difference under most types of seeing. Excellent results can be achieved with 15fps under some types of seeing.  Con (Ittaku) swears by 30fps under the good conditions he images under.

 

If you already have a 2.25x (is it really 2.25x in practice?) barlow, there's no real need for a 3x.  If you're imaging under conditions which exceed that which the 2.25x can excel under, then drizzle stacking in AutoStakkert will make up the difference in the potential under-sampling. You'll be fine.

I got the 462MC for planetary this year but I didn't get a specific IR cut filter for it. I used it in two configurations - one replacing the eyepiece in a diagonal, with a barlow, and the other replacing my DSO camera attached to a filter wheel, without the barlow. I have a 2" IR cut in my filter wheel which I could remove and put in my diagonal, but that's inconvenient. Is there a recommended IR filter for the 462?

The playerone imx464 is currently best planetary camera on market at full resolution it’s 97fps, if cropped to 462c chip size it’s 139fps, cropping further to 1300x700 gets you around 185fps , it come with a ir/cut , it has same ir sensitivity as 462c , highly recommended

I have the 850ir and the astronomik 642…. I actually think the 642 performs better but either will steady seeing and give great images… the 642 actually cuts ir above 850 which in my opinion gives slightly sharper images…. Other advantage is if mounted on a flip mirror you can still see enough visually for centering
