Starting to do some science in the observatory – Jupiter, Uranian Moons and discovering asteroids

Over the past week or so I’ve been sorting out cables in the observatory and testing cameras. Still only on al alt-az mount without guiding, but a good enough setup to try a few things. Continue reading Starting to do some science in the observatory – Jupiter, Uranian Moons and discovering asteroids

First image in the observatory – M57

I tried taking some deep sky images last night for the first time in several years. Not an ideal setup for my C9.25 – altaz mount, no guiding, no PEC training, no electronic focuser, unmodded Canon 400d and a bright Moon. Given that, I’m happy with the result of 20x30s exposures on one of my favourite objects: Continue reading First image in the observatory – M57

Building an Observatory – Part 7 – First Light! Phase 1 complete!

Well we finally got first light! ok it was sunlight reflected off the clouds but it counts!

The first job today was to drill down into the concrete base to anchor in the 12mm bolts in place. The local building suppliers had Rawl R-KEM which is a two part epoxy that comes in a 300ml tube, it mixes in the nozzle so its easy to apply. With the bolts in place the pier was put in place and leveled: Continue reading Building an Observatory – Part 7 – First Light! Phase 1 complete!

Building an Observatory – Part 5

The shed part is pretty much complete now. Last weekend I made the door, got the rest of the weathersheeting in place, finished the roof, and got the wood preservative on. I also added a 2×3 to strengthen the beam with the castors so that the ends no longer touch the track; I’ve to do the same to the other side sometime, but as it stands I can move the roof easily with one hand.  Continue reading Building an Observatory – Part 5

Building and Observatory – Part 4

In between rain showers I’ve managed to almost get the building work completed on the observatory. Building the support for the roof and rails was easy enough though the beams were very slightly warped; this doesn’t matter too much as it can be corrected by placing the rails in the correct line.

The roof was trickier than I thought. I hadn’t tried to build a roof before and it’s quite easy to get things out of alignment and not straight. It’s not perfect but more than good enough for my requirements. Continue reading Building and Observatory – Part 4
