May 6, 2017: DLSR moon with 80mm

[michael.h.f.wilkinson]

Unexpectedly, there was a gap in the clouds. I rushed out the APM 80mm and snapped a load of raw frames with the EOS 700D and 2.5x PowerMate. I stacked 40 out of 65 frames.

It wasn't quite dark, so the background is a bit greyish. I might correct that later

Hi Michael, nice image. Do you use a 2" powermate. I was wondering how dslr users up their focal length without vignetting problems.

The 2.5x PowerMate is only available in 1.25" form. That is large enough for my crop sensor, at least for the moon

Thanks, thinking about it I'd still need a 2" barlow because I want to use my coma corrector to do a very large mosiac.

I much prefer using my planetary cameras for mosaics, in particular the ASI178MM. Might do a comparison with my 80D later, but I expect the ASI178MM to trounce the 80D

Nice image Michael, I have thought about getting a powemate myself but I seem to get reasonable results using a lens teleconvertor on my DSLR instead, I wonder if they are similar in optical design..
