Thanks Rob, I’m pleased that you enjoyed the bigger image.

I think the overall image quality is more related to the good seeing conditions and the capture/processing via the ASI 174 MM CMOS camera rather than the Mewlon 180. I suspect that my C9.25 would have done just as good a job?

I tried a x2 TV Powermate but the seeing broke down so I returned to using the Tak x1.6 Extender and captured 3000 frames in each AVI and used the 50% setting (i.e. use 1500 frames) in AutoStakkert2!

The final mosaic was 4468x4441 pixels and down-sizing to 2560x2560 also adds some “pop” to the image.

I also use the Topaz Plug-Ins in CS6 and they help boost the contrast and detail and display the tonal range more effectively so that whites are not blown out.

I have added an “unprocessed” 1024x768 full res crop to show what the data looked like coming out of AS2! and Registax, before it went into CS6 and the Topaz Plug-Ins.

Cheers

Dennis

EDIT: Just to complete the picture, I have just attached a processed version for comparison.
