Commentary on things related to astronomy, astrophysics, astrophotography, equipment, design, processing techinques, people, places, events, etc. and other such things that may not fit well elsewhere.
OK, I have heard many times about BackyardEOS for controlling Canon EOS cameras used in Astrophotography. Unfortunately my 1st generation Digital Rebel (300D) with its now ancient DIGIC-I processor is not a supported platform. Even though it does have USB and you can trigger the shutter through that you can only use the predefined exposure …

Shot from the backyard in Allen, TX on 2013-01-20 @ 2300 CST. The seeing was pretty darn good, humidity was high as was the light pollution but it was bearable for my first time seriously out with the scope in a while. Camera control was through BackyardEOS which I’ve decided is the bee’s knees. If …
After seemingly unending weeks of temperatures over 100F during the day and 85F at night with at least 60% humidity we get some relief. It came in the form of Tropical Storm Lee which pummeled the East Coast with rain for days on end once again flooding large portions of Tennessee but the break in …
It’s been oppressively hot here in Tejas recently but I’m starting to get the itch to play under the stars once more. I needed to give my declination axis a tune so I did that last week hoping to use it when it was actually looking like it might get into the 70’s overnight. Granted …

I was digging through some old data and thought I might reprocess my M13 data from three years ago. Man, what a difference! Some of it is software, some of it is technique, some of it is experience. The old M13 on the left, the reprocessed data on the right:
Messier 44, The Beehive Cluster, Praesepe. This is one really large object. It is 95 arc minutes (a bit more than 1.5 degrees) in angular size. It’s big enough that it won’t fit in a single frame on my Canon 300D with my f/5 Schmidt-Newtonian scope. That officially makes M44’s dimensions Big by Large! Located …
Betelguese focus test shot from 2010-03-13. I had to use diffraction spikes since I left my regular focus mask at home. It looks kind of cool with the diff spikes, even to a guy that generally doesn’t like them.
A little venting on Meade QA and the direction they should be heading.
I took this image of M42/M42/NGC1977 on January 12th after re-remembering how to accurately align a mount that isn’t permanently installed. I took about an hour and a half of subs with several having to be rejected for one reason or another. I still am having a problem with my serial shutter cable which I …
