Caldwell 38 - two different scopes

[Ben Cartwright SASS]

I used both the SLOOH 20" and 17" planewave scopes at the Canary Islands Observatory to see what the differences would be. The dust lane on the 20" is better as is the sky itself, although I may have used a bit more contrast. The 17" I think shows a little more detail
the 20" image was processed with Nebulosity and Photoshop, last year while the 17" was processed in APP - Astro Pixel Processor and finished in Photoshop, I think I need to work the background just a bit more, so I would call it an image in process.

20"



17"

Hey Jeff, those are both REALLY good images! Details are great in both....not sure which one I like best.
Great Comparison!
