That is 55mm from the MPCC *I think*.
You'd best check that as I'm not 100% sure!

LOL, thanks for taking a stab at my DSLR version Rob.

Looks like there is some amp glow along the bottom too, I think I know how to remove that using Startools wipe...

There is soooo much noise in the DSLR compared to the cooled QHY, I did take some darks later, but the chip temp was all wrong so I might try some more to match later once I can get the hang of removing the gunk such as sky glow, vignetting and amp glow.

Thanks for your efforts

Cheers

Fox

I see an sbig in the 4sale forums. So long as the heater mod has been done it's good to go as a osc.

Not to mention the qhy9 with wheel and filters that are on the block

Hmmm, thanks Robin,

Minister of finance is currently reviewing the federal budget, unless I can sell my boat, approval will be difficult.

Thanks for the tip though

Cheers

Chris

Hey Peter,

Here is my processing "help" thread with the dropbox links to the M83 FITS and CR2 files for processing, there is 20 mins of each with no darks and the two stacks I did there as well.

Here is my "result" of about a week's worth of time I spent (on the Canon data - and I cheated by adding some bias and darks to it )

Cheers

Chris

I'm having a read now.

Can you take a photo/draw a diagram of how you have the QHY8 setup and attached to your scope? I'm keen to reduce the vignetting for you.

Also, whilst you have the camera, image some faint targets, bright ones are not a challenge for the DSLR, try some faint targets where the noise will make a difference and see how they compare.
