What camera to use with C6 w/1.25" diagonal?
Posted 26 May 2013 - 04:16 PM
1. Canon 60Da (reduced IR filter)
2. Olympus E-MP2 (seems like a cost effective camera)
3. Canon EOS t2i (seems to be a standard)
4. Canon 1100D (modified)
5. Panasonic GH3 (great semi-real time exposures)
6. Canon 650D (modified)
I know there are various sized chips in each of these. My question to the forum is, what would you recommend and why?
It would be great to find an all purpose camera that I can use for AP as well as other things, as I wouldn't mind revisiting HD film production work I've done in the past. If I went out and invested in a modified camera, I probably wouldn't be able to use it for anything else.
I should mention I will also be getting a Stellarview 60mm straight through finderscope with a 2" focuser... could I conceivably produce better results with it over the C6?
Any help would be greatly appreciated, thank you.

I'd go with the modified 650D(T4i). I don't think the T5i is fully supported by all of the astro programs, but it will be soon. Of course, it's new and untested, but should also be a good performer.
Now, if you want a camera for daytime HD stuff, buy that. Then buy a used modded XSi or T1i for under $500. Keep your eyes in the S&S and classifieds. I like leaving my DSLR on my OTA. So having two cameras lets me have one where I need it when I need it. I tend to buy used, which covers the difference. With a mod, you are killing the warranty anyways.
It is true you can use a modded camera for daytime photo's, but you do have to take a CWB in each type of lighting you are in. Personally, I think this makes your photo's look better, but it is a bit more of a chore.
I like APS-C sensors because they are large. You can always crop, but if your target doesn't fit in the FOV there is nothing you can do.
Modified cameras also work better on larger targets. Or maybe I should say H-Alpha targets tend to be larger. I'm not sure about the SV60mm. I have no experience with it. But a small apo refractor will most certainly give a newcomer better results then a long FL SCT.
Also, a similar sized CCD sensor would be over $5K.

These would do much better on the Stellarview.
For the C6 I'd go with something like an ATIK 314L+ or comparable sized.

Adam, I would use focal reducers on the C6.

Usually with a gem style mount you will mount any cameras and such directly off the back of the ota. You'll also need to be very careful about the spacing when you are using focal reducers so the adapters and spacers will be unique for each type of reducer/camera combination.
On the other hand if you are going to buy the complete 6SE alt az mounted scope then you will need to consider the clearance with the base when the scope is pointed towards the zenith. In this case I would regardless of what camera you choose get a 2" SCT threaded diagonal. These are much more solid and robust. Then you'll mount your focal reducer, any spacers required and then your camera.

As Adam said though, use a T-adapter and dont use the diagonal.

Cool, how well does it perform modified? And if I may, how does it compare with the 60Da?
A fully modded camera will show more H-alpha than the 60Da. Also, it takes me about 5 seconds to change my T3 from Auto White Balance to Custom White Balance to take regular daytime pictures.
This is a good review. It sums it up pretty well at the bottom with the "conclusion"

Wait a sec, the AT72ED is pretty decently priced and it's APO. I should go for that instead of the SV60 as a finder!
A better choice IMO is the AT65EDQ. It is a true apo with FPL-53 optics and a built-in field flattener. You will need a flattener with the 72ED and the AT65 comes with some pretty nice rings. By the time you buy the rings and flattener you'll have almost as much in it as you would the AT65EDQ with premium optics.
