Powermate for planetary

[emyliano2000]

Hello guys and girls.

I would like to start some planetary imaging and I was wondering what powermate should I go for. I've seen a x5 on ASBS but I'm  thinking that it might be too much and I wouldn't  want to buy something just to keep it in my drawer.

My gear is in my signature. 

Thanks

Your scope is an f5 correct...?

in that case the 5x powermate would be perfect as at f25 this would be very good for planetary imaging, you could also consider the 4x 2" version....that's my newbie opinion anyway...

F/25 is near perfect for imaging with cameras with a pixel size around 5.5 micron (like the DMK21, or ASI174MM/MC). For cameras with smaller pixels (like my ASI224MC or the ASI120MM/MC), F/16-F/20 is better. For my ASI178MM I find F/11-F/15 work best.

I'm gonna be using my canon 700d. It has 4.3 microns pixel size. Maybe I should aim for a 2" x4 then.

Will I be able to achieve focus with the 200p and dslr? I didn't upgrade my focuser so I only have the standard one. Would I still need to use the baader mpcc and guider for planetary imaging?

How would I set them up?

5x your pixel size to get the optimum f/ so yes a 4x is good. You don't need to guide or a coma corrector. For planets you use video captures to perform 'lucky imaging'. I can't answer the focus question, sorry. Just be aware before you invest that the best targets are poorly placed for some years now in the UK. It will be 5 years before Jupiter is nicely elevated and nearer 11 years for Saturn.

I'm not loking for something fancy pancy, I just wanna take some planetary photos that look better than the ones taken with my phone.
