Yes, but you exposed 400 speed film, his is only 200, f4 vs f5.6, You pushed your film, his doesn't say....

It's a nice shot, Raymond, but it seems to me a little weak.

I took a photo of NGC7000 on last august using a Vixen R200SS (200/800) using the same film but the nebula is stronger.

What software you used to guide with the webcam?

Dear all,

Single image of 30 min North America (main target) + 1/3 Pelican Nebula, taken by Leica M280mm lens at F5.6, on EM200 mount with webcam autoguide by 50mm finder (183mm focal length), at East Dam, Sai Kung, Hong Kong on 13-07-2004.

Focus is a bit soft due to very dim viewfinder in Ricoh camera body (20 years old).

Transparency : about 7/10
Stability : about 7/10
Wind : mild
Light pollution : some squid boats there with strong flood lights.
(one of the very good clear summer nights, if not light pollutted by squid boats).
