Pointing East vs West
For some reason, I have always had trouble trying to shoot objects to the West (with the mount tracking things as they are setting). I have tailored my whole astrophotography psyche to […]

Elbrus Solved and Unsolved images
These are a couple of images that I am trying to solve in Elbrus. This one solved OK, with these parameters. This one, taken after moving the scope, but without rotating the […]

Lament of the sleep-deprived
Believe me, there are worse things in the astronomy hobby than being so tired that you just can’t face another clear night. Normally, when the moon is bright in the night sky, […]

minor maintenance
I rebalanced the scope so that it’s balanced rather than purposely off-balance. I also added a 12v fan to the scope to hopefully help control dew. We’ll see if it does anything. […]

I had some tuning to do tonight before I could get started. That ate most of my effective imaging time. I decided to shoot without the Ha filter, which meant going back […]

Special Guest Star takes the mount at Hilltop O
The Astro Jedi needed somewhere to store his light sab—- I mean, bucket, and I was only too happy to accommodate him. I have decided that I need to come to a […]

Dome shutter is motorized again!
I finally decided to bite the bullet and fix the shutter motor. Things went sideways last winter, and I’ve been opening the shutter manually (and tying it shut with rope, so we […]
