Andromeda – M31 September 04, 2015

This image is of the Andromeda galaxy taken on September 04, 2015. This image contains 6 images at 5 minutes a piece, along with 20 flat frames, 20 bias frames, and 20 dark frames. Processing, and post processing were all done in PixInsight.

Andromeda 09-04-15

This is only the second image I have ever processed completely in PixInsight so this is still a learning experience for me. I followed a tutorial on Light Vortex page on the steps to get a fully processed image using masks, and HDR tools.

I know I have been slacking on updating and posting here to my blog and I hope to get out more in the near future to continue imaging and editing the cosmos for you all to enjoy.

Equipment:
Omni XLT 150
CG-5 Advanced Series Go-To
Lin_Guider in Linux for autoguiding
Orion Starshoot Autoguider
Modified Canon 350D
Baader MPCC Mark III Coma Corrector

Last week I broke down and bought PixInsight

Since my 45 day free trial ran out before I ever got around to really using it I decided to buy it for good reasons. One, it is a beast for astrophotography! Two, it runs natively in Linux which is a major plus for me since I mainly run Linux. I maintain Windows on my laptop for now only because I'm working out some kinks on getting autoguiding to work on Linux on my laptop.

This is my first attempt at PixInsight, and I can say I'm quite please, and proud of the final results. The comparison of these two images is quite a difference. I still have a ways to go to get better in PixInsight, but for a first attempt I couldn't be happier with the results.

These two images were created from the same exact data. I had a bit of an issue getting rid of the red blemish in the upper left corner of the PixInsight image. I think a bit of light bled through when I was shooting my dark frames which may have caused this since I forgot to cover the camera with a shirt like I usually do, which allowed light from my back porch to bleed through on the dark frames.

I'd also like to thank +Stuart Forman for helping me get started in PixInsight.
