Nice work, but the ED80 is not an achromat.

A scope doesn't have to be a triplet or quadruplet etc: to be classified as an APO.
The ED80, ED100, and ED120 have always been considered APOs, as a bit research will confirm.

A few things to be proud of with this result Tony, it's a really nice shot, well processed and you managed some 5min unguided subs @ 600mm focal length. Amazing! What mount were you using, is it the AZ-EQ6 GT?

Tony, I noticed this nebula in Stellarium, and didn't really like the look of it. But after seeing your photo, I am determined to give this one a shot. Your image is fantastic!! I've lost a couple of nights of imaging because of problems with my gear (coma, fingerprints on filters,...) and the weather hasn't been too good. Thor's Helmet is up next, and I think after that, the Pencil nebula. Thanks for the inspiration!

Btw, what processing tool(s) do you use?

Regards,
Stéphane
