Some captures with my Infinity

This were on my C11, with an Optec F3.3 reducer and an Omega UHC filter (does not block IR).  15-20 second exposures stacked for around 5-6 minutes

Nice images Mike.  What adapter are you using with the Optec.  I notice coma but no vignetting.  I have the same Optec and didn't think it would work as well as you're doing.

Hi Don, I do get some vignetting, but use the Histogram to eliminate its affect.  It is most evident on the Horsehead pic, where you see stars to  the edges but the actual nebulosity ends prior to that.  I use the adapter recommended by Optec.  It was the 1.87 adapter

Took this of the needle galaxy

Also got M3

Some more great captures Mike. Still saving for my Infinity.

Thanks for sharing

Could be good if you post your exposing data for each picture. I can't do the same quality with my Infinity.

Most objects are 15-20 seconds exposures stack for 5-6 minutes and very careful adjustments to the histogram.

The M3 globular cluster was different.   It was 1.5 second exposures for about 700 stacks.  I had to do careful movement of the white and gray lines of the Histogram to get such a great image

[StarMike]

learning how to optimize the histogram takes some time and patience.  Each time out, I get better at it

Thanks for your answer.

Is your camera black and white?

[StarMike]

Yes, I have the monochrome verison.  I chose it because generally, monochrome is more sensitive than color
