NGC 2023 – Horsehead and Flame Nebulae 01-06-16

That was a tough processing challenge working through all that light pollution to reveal the Horsehead and Flame nebulae. This is the best I could produce with my minimal knowledge of Pixinsight, switching between Harry’s Astroshed tutorials and scavenging online for other tips and tricks to editing DSLR images in PixInsight. I’m pretty pleased with this as it is hard to pull out much detail after removing light pollution without adding too much of that blotchy grainy noise in the background.

Taken from a light polluted zone (red Bortle scale)
Telescope: Omni XLT 150
Mount: CG-5
Orion Starshoot Autoguider
Guiding in Linux with Lin_Guider
Modded Canon 350D

42 images at 5 minutes a piece. With 30 Flats, 30 Bias, and 40 Dark frames.

Straight out of the camera single image.

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.

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

This weekend worked out great for my Linux and guiding test

Successfully got Lin_Guider to work under Ubuntu 15.04 which I could never get to work under Mint with my Orion StarShoot Autoguider. Not only is guiding working, but so is image downloading from my camera to my computer. Image below is Lin_Guider guiding on a star near M27.

I also just ordered the Celestron RS232 cable and RS232-USB so I can us Cartes du Ciel for Goto controls of my CG5 mount.

Just about all the pieces of the puzzle are finally together. Only thing left on the big astronomy list is an observatory, but that is still a ways away from happening.

Linux and Astronomy Frustration

Anyone that follows me knows that I have been relentlessly (bashing my head against the wall) trying to get Linux as my main astrophotography setup. I can successfully plug in my Canon 350D and download images instantly onto my computer with just a USB cable and the software Entangle: http://entangle-photo.org/ I do not use it as my means of controlling the shutter since I have an intervalometer that controls the shutter for imaging.

I use an Orion StarshootAutoguider (SSAG) as my guiding camera and a CG-5 mount, which I am attempting to control using Lin_Guider: http://sourceforge.net/projects/linguider/ I have successfully gotten the SSAG working to show me the stars it is imaging, but I still can't get the program to talk to the mount and send pulses. I can't calibrate or guide with it yet. This is the last thing I need to get working before I can be completely up and running in Linux, and finally be able to ditch Windows all-together.

I have been trying like crazy to get the computer to talk to the guide camera and mount, but I just can't get them to work yet. I'm probably missing something extremely simple.

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.
