NGC6888 with 140mm refractor

Had some good seeing last night and decided to shoot some H-alpha with the new 140F7.5. The image was taken at F5.7 with the TCC and STL11K camera. 6x10 minute exposure, reduced to 1/4 size. The nebulosity above NGC6888 reminds me of parts of the Veil.

8) 8) Cool. I'll be waiting for the notification! You are using the 155TCC?

Rolando,

Excellent result. A lot of fine and delicate structure.

Here is a color version, taken with Baader narrow band filters, Ha, O3 and S2. 1/4 size.

What method do you use to achieve such perfect focus?

Thanks!

I finally was able to get a decent night to try all 3 of the Baader filters. In processing I tried to combine the colors in such a way as to get more natural coloration. This shot uses H-alpha for red, O-3 for blue and an average of H-a, S-2 O-3 for green. This shot shows the full view of the camera with the 140 operating at F5.7, image reduced to 1/4 size.
