Modified 6D Mark II & Camera Mount Sizes

One of Hutech royal customers – Klaus Brasch sent me his 1st light with a modified 6D Mark II. I don’t remember I have seen this kind of a close-up M8 shot before. Overwhelming!!

Here is his beautiful pictures with comments on Canon 6D Mark II.

Hello,

I dipped into my astro toy budget recently and bought a new Canon 6D Mark II DSLR modified for deep sky photography by Astro Hutech. Having happily used my earlier Hutech modified Canon 6D for several years now, I was curious to see how much improved the Mark II model is. For one thing, the new Canon CMOS sensor is rated at 26.2 Mega pixels v the older 20.2. Would that make a visible difference? Second, the new camera has an articulating LCD monitor. Would that help framing and focusing and make things easier for my aging back and bones? Finally how high could I push the ISO settings on this camera without generating excessive electronic noise?

I chose two types of popular deep sky imaging methods, wide field piggy- back of the summer Milky Way with a 50 mm Canon lens at f/4 with no extra filter, and then a close up through my AP-155 f/5.2 refractor of one of my favorite nebular complexes, Messier 8 and NGC 6559, through an IDAS LPS-V4 filter. All frames were shot at ISO 6400 and each final image is a stack of 5 x 30″ to 2 minute exposures. Final processing was done with Photoshop CS 6.

My conclusions? Resolution is visible better than in the older Canon 6D, the cameras long-exposure noise reduction is very effective and the articulating LCD monitor is great for my creature comfort :).

Thanks again for sharing your recent gorgeous pictures and info on 6D Mark II performance.

BTW, I mentioned some mount sizes several days ago. So I was curious how each mount was different.

From right, Canon EF, Nikon F, Sony E and Fuji X

Nikon F and Sony E are almost same ID. But Sony has no a mirror and mirror box. So looks to me, current Nikon F mount seems to have most disadvantage especially when used with telescopes. I applause Canon they decided to change the mount from FD to EF while there were many controversial that time.

Now Nikon’s new mount – Z will be 1mm larger than EF. So I’m sure Z mount cameras will give Nikon users the huge benefit soon.

Keep in mind, all of above adapters are BORG-made. Unlike conventional T-ring, ID of telescope side has almost 50mm. I also applause BORG to have set this size long time ago.

BORG will make Z-mount adapter as well. But no need to enlarge ID of telescope side. So current all reducers and flatteners work with Nikon Z-mount camera as they are without losing large Z-mount benefit.
