This is one of my favorite nebula and I will try to shoot LRGB later when the Moon and weather allows.

This is 200 minutes of Ha.

We made some interesting plans for our exoplanet survey and agreed some common processes. Thank you guys, it was great fun! Now let’s get to work!

This telescope is one of Searchlight Observatory Network stations owned by Caisey Harlingten.

Main usage of this telescope is for scientific work but time to time I can use it for taking pretty pictures as well.

This is the latest, NGC 925:

There was a mystery error with WordPress and it took me awhile to solve it and update WP.

A lot has happened since last post so I’ll be posting some new images, especially the ones taken in New Mexico.

I’ve been very busy with my regular day job which has demand a lot of my valuable ‘free’ time as well. Last night was clear and moonless for a long time so I kicked my self out to shoot some additional frames on this challenging target. Now I have total of 5.5 hours of data. I’ll continue shoting this when time, clouds and moon allows.

Couple of clear nights and no Moon. Still quite freezing though. This image has following exposures: HaLRGB = 120:70:55:55:35 minutes. I was applying Adam Blocks methods for image processing as much as I could. Here is the result.

M81_82-HaLRGB-v03

I would still like to get some more Ha, Blue and Luminance. Ha subs for this were 30 minutes each which is a personal record for exposure length.
