Thanks for all the very helpful replies!......given my current method and lack of tracking abilities, it’s nice to know there’s not much advantage to a new camera at this time. I’ll keep doing what I’m doing until we move later next year.......that solution can include a dedicated pier and whatever Mount is required. With my current backyard situation, my neighbors trees present an ever growing problem! Lol
I do have a Celestron C5 though and never considered that for planetary.....with an EQ mount, could I produce better images than with the 12” dob? Focal length on that is 1250mm......I just thought the aperture was too small?
Hmmm, good question. In my earlier post, I gave links to what I was able to achieve using a 6" and 9.25" with tracking on both. The 5" could produce an image similar to my 6", the 12" should give better resolution than the 9.25", assuming the seeing and elevation are similar. The difference between a 5" and a 12" would be even greater, however would an untracked 12" produce better images than a tracked 5"? Most probably, but the process would be so difficult it might not be worth it.
However, I would recommend starting with the tracking 5" - you will find getting focus much easier (as the planet stays on the screen), capturing 3 - 5 minutes of continuous planetary imaging and stacking them will be so much easier, and getting a good result might be enough to learn the process. Getting a good result with the 12" will be better than the 5", but the experience in using the 5 will assist you with the larger aperture.
One possible solution might actually be a new camera, something like the ZWO183MC. This is a large sensor camera (similar to the Canon) but with smaller pixels (2.4 microns) and would allow you to get a lot more frames as the planet drifted across the sensor than the 224. It's twice the price of the 224, and you will still have the problem of not being able to track the planet, but it might be a solution.
I'd probably still recommend a tracking mount (try the classifieds area) over the 183MC, but it's an option. By the way, how are you currently capturing your images (full frame video?), and can you share some images you have made?
