7/1/2018 – Jupiter and Saturn

Here are two images from Saturday night at the River Ridge Observatory. Both were shot with a monochrome camera using red, green, and blue filters and a 9.25″ SCT. Each color was picked from the best 50% of about 3000 frames (30 seconds of video). Stacked then aligned and combined in Photoshop. Jupiter was shot with 10 millisecond exposures while Saturn required 50 millisecond. Saturn was barely above the trees and I should have waited but frankly it is near the southern limit of its journey around the Sun and doesn’t get too high. Jupiter was just past the meridian. I may work with it some more when I have time, the raw footage looked like it would be better than this.

6/15/2018 Transit of Jupiter’s Red Spot with Io and it’s shadow


Friday night I went up to the River Ridge Observatory to shoot some planets. I started with Venus which is about as high in the sky after sunset as it will get in this apparition. It was disappointing so I moved on. Next up was Jupiter. I’m using a monochrome camera with RGB filters so here we have the combined result with the red, green and blue images that went into it. The color image is softer than I’d like but shows Io and it’s shadow that were transiting the disk of Jupiter this evening, They were both near the meridian of Jupiter when I started and visible on the laptop. Below are the red, green, and blue filter monochrome images that went into the image above. Notice the red spot is barely visible in the first image which is the red channel and darkest in the last image which is the blue channel.


Camper Build 6/9/2018


It’s the hottest part of the day so I’m taking a break. I’ve got the frame on the future camper now,  most of it at least. Now I will turn my attention to the roof. The walls you see here are about 56 inches tall. I can stoop under the top boards as I pretend to go through the someday door. This clears the lowest part of the garage door by 7.5″ so I have 6″ to play with, giving 1.5″ for error. The lowest profile vent cover I’ve found is 2″ tall when closed so I have 4″ to work with. The camper will have a lifting roof that will raise enough that i can stand up in it at least most of the way. If for some reason I can’t pull that off, then I’ll just add enough to this so I can stand up and the forget about working in the garage.
