Camper Build 8/11/2018

It’s been a while since I posted about the camper build. Two months to be exact. I kind of had other pits to put my money into for a bit and also had to wait for some back ordered items to come in. Those items were reasonably priced aluminum piano hinges and a low profile roof vent.
So here we see the hinges in action connecting the flip-up panels to the walls. In the first picture they are folded down, like a box, then up in the next. The flip up panels will lift the ceiling by 15 inches so that I can get the camper in and out of the garage and still stand up inside, even if I grow three inches.
Finally the “lid” as everyone agrees it should be called. It’s upside down now, the exterior plywood that will be the top on the floor then 1 inch of rigid foam and then 5 mm interior plywood that will be the ceiling, All glued together with paint. I’ll let that set with cat litter on top for about a week. As it is, the lid is about 90 pounds. If I’ve messed it up and it sags then people who have done this before recommend 2 inch foam and no plywood, just the canvas skin. That would eliminate about 60 pounds.

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.
