M106, Spiral Galaxy in Ursa Major
My first attempt at M106 came out not-too-bad. Could use better focus. And more exposure time. And finer image scale. …but not bad. I’d like to take this opportunity to thank the […]
Re: CR-1 shims
Hi Jimbo, Sounds like you need to increase the load capacity of the focuser. Turn the 2 set screws located under the MoonLite logo in a CW direction about 1/20th of a […]

M82, Spiral Galaxy in Ursa Major
Since my shots of M82 are coming out a lot better than my shots of M81 at the moment, I decided that M82 deserved its own space. This is a crop out […]

M81 and M82, Spiral Galaxies in Ursa Major
This is my first attempt at this pair with Veronica. The image was shot under a 16-day moon. I’m impressed by both the amount of detail I was able to pick up, […]

NGC 2237, The Rosette Nebula in Monoceros
An example of serendipity. I was trying to find this nebula, was using GOTO (on the CG-5GT), couldn’t be sure I had it, so I only shot one frame of it. Turns […]

D70 IR Intervalometer
This is a great little device of my own invention; it’s a “smart” IR remote control for the Nikon D70. I set it for exposure length, exposure count, and delay between exposures, […]

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 […]
Trixie 2017 – tube mods
I finally got around to cutting the MTA-UTA tubes to length; the only eyepiece that would come to focus with the focuser spacer in place is the Televue 55mm Plossl. If I […]
