NGC1491

Here is a recent image I made of NGC 1491. I used my C8 at f/5 - it is a slower narrow field for me then I normally use with my H-Alpha filter. Normally I try to shoot HA at f/2.8 to f/4 with 3-4 minute exposures. This image includes a 6 x 5 minute exposure - I really can't go too much longer than 5 minutes with my webcam.

I have attached an image, but a full size image as well as exposure and processing details are at:

It is very hard to believe you can get such nice shots with a webcam... you definitely have grasped the "HOW TO DO IT".
Great shot Jim! Wonderful colors & detail!

Happy Holidays!
