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.
