The 120ST achro does better in H-alpha as you might expect. Here's a stack of about 10x5 min subs processed with Nebulosity. Manually guided with a Stellacam II.

Enjoy,


David

David,

That is a nice shot....I also have a 120ST, and have been contemplating trying an H-alpha shot. This image gives me a reason for doing so...what camera was used for the image?

David,
Pretty cool image. The H-Alpha is an interesting result. Makes the 120ST look pretty good.

What is the bandpass width of the H-Alpha you used?

I applaud your driving skills with the Stellacam, David.
You have great detail in your image, and though people often overexpose the outer 'shoulders' of the Crescent, you've handled that well.
You might want to back off a bit on the sharpening, the stars are starting to show as panda eyes.
Good job.
