Five hours of Guided images
…with zero dropped subframes. I spent a little time refining the polar alignment last night. I am still getting some drift while running unguided; I calculated it to be about 6′ from […]

Veronica gets a shot at the NJP
Buoyed with the success of the NJP with Pumpkin, I decided to start upping the ante. Pumpkin was mounted offset to one side, but I decided that Veronica should be balanced over […]

IC1848, The Soul Nebula in Casseiopeia
This is the first time that I’ve been able to catch this object. The autumn nebulae are elusive for some reason. But I figured I’d try it before it dips below the […]

Pumpkin unguided testing
I hesitate to call this a postable image. It’s really just “what I could get” with “the skies I had” and “the equipment as it sat”. 5 years ago, I would have […]

NGC2244, The Rosette Nebula in Monoceros
With the newly-tuned mount, I decided to try Pumpkin on some more unguided imaging. After the “baseline” from the previous night, I now wanted to see what this MFWB could really do. […]

Pumpkin by her lonesome
I mounted up Pumpkin by herself tonight. The mount’s been having a problem with guiding, very rough behavior in RA. I’m going to be tuning the mount up tomorrow, but the sky […]

Welcome back, Veronica — and welcome back, awful guiding problems
Well, it was clear tonight. That’s about the best thing that happened tonight. The scope booted up and is working eh, ok. The polar alignment is off, and I never did check […]

The camera is out there capturing an unguided shot of M42 for the RCC’s first light image. …and here it is. As usual, it’s another M42. This is 30 frames, 2 minutes […]

Pushing the limit — Pumpkin in a windstorm
The seeing was pretty bad last night, as in “wind blowing so hard that I thought the leaves rattling were raindrops and ran outside to check”. This wreaked havoc on Veronica’s guiding. […]

Pumpkin's Return — A breath of fresh air
After 10 days of fighting Veronica, I’d had enough. Tonight, I swapped the camera back to Pumpkin, rebalanced, and tried my luck at two targets. With Cassiopeia showing above the house, I […]

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 […]
