Some of the smaller stars are square. I could drizzle possibly to increase the pixel resolution since I've dithered a lot. But now I'm using a 2600MC pro, and I'm about to take that off and use a 294MM pro I have sitting around. I have a whole bunch of cameras that I move around between scopes. But the 294MM pro is probably the best for pixel scale now that they unlocked the smaller pixels.

The Redcat is a pretty awesome scope. I've been using it with an APSc sized sensor. Color correction towards the edges is not as good as the center. So your camera will be a great match for both field of view and pixel scale and probably not show much color error in the corners. Basically blue isn't as in focus towards the edges, but you can only really see it if you zoom in 1:1. Pavel has made me items early on for the Redcat (I had one of the first), he's been great to work with, and finally got his new kit after moving from a Moonlite focus motor to the EAF.

The Deepsky Dad focus kit for the EAF is great for this scope. Keeps things nice and compact. Now I just need to get some shorter cables.

I have only ever used ZWO. I've owned about 6-10 of their cameras from inexpensive guide cameras up to the ASI6200. They're regularly updating drivers. They generally put out fixes very quickly. From what I've heard QHY has solid hardware, but issues writing software/drivers. I do have a pole master and the Mac software stinks. I tend to run it on a cheap PC laptop I have instead. ZWO is well supported on all systems, but I've seen a fair share of people getting hardware that's DOA, though in all cases, I've seen them get replacements. I personally have never had a bad camera from them. I'd be interested in hearing from QHY owners, as I like their cameras.

Doug, thanks for chiming in. This is the type of feedback that will aid in making this stuff a reality.

Regarding your comments on Point 2, there is already a mechanism in place to average seeing by taking multiple shots. Wouldn't this go a long way in making these readings more accurate? I think for most users, as you say, would benefit from some form of automatic characterization. Unless those users are familiar with their focus system and it's characteristics and what will work best for any given focus algorithm, there is no way for any beginner to read the existing tool tips and understand the correct parameters to plug into the software interface.

On point 3, I love that you've done this. I know you send me a message offering access to the code, but I don't have the technical fortitude to apply it. Would be happy to test it out though if it gets merged into the system. But at least in the beginning, I think all you would need in the interface is a simple field on the capture/sequence tab below the existing refocus parameters to input a #steps to move / degC. Of course, this leaves it up to the user to manually plot out and note focus positions during temperature drops to characterize their system, but it's a start. Longer term with the analytics tab, temperature and focus position could be plotted over a nights run (even multiple nights) and that step change/degC could be automatically populated into the field for a user.

That image shows your main camera is selected, not your guide camera, so that's why there's no suitable frames.

Jo, I hear ya. I had that same exact scope and focuser. It's known for the issues you mentioned, and is the first one I ever replaced with a Moonlite. Though I didn't get a $2500 focuser, I got the more moderately priced regular Crayford they offer for a few hundred. In any case, not all focusers suffer from this, even at the entry level.
