  1. The weather forecast here in Stockport was terrible with rain most of the day so I didn't even bother with a scope. However, just before lunchtime it started to clear in short patches so I drove home to get my gear, timing it so I got back to work for 12.30 and with about 15 minutes left of my lunch. I am glad I did as for about 30 seconds, and just as I put in my second eyepiece into the binoviewer, the sky cleared enough to see part of the transit and then clammed up again. It was worth it though.

  2. Well I made the door but not fitted yet. In between the amazing rugby and a Halloween party it's been a busy weekend..........

    I'm supposed to be Georgie out of the film It. However I seem to resemble more Brian Cox after a weekend bender.

  3. Hi Ron

    The rear of the obs faces north to Manchester so bad light pollution. 

    With the roof open I can just get Polaris and about 60% if the front is open towards the best skies I have while still masking houses. The end of the garden is 25 feet lower than the house so I gave to mask this too. Still worth the effort.

  4. Managed to get the roof on. The bitumen sheets worked pretty well but there's more of a gap than I'd like but hopefully there's enough overlap to prevent leaks. It would take pretty unusual weather to be at that angle and direction so fingers crossed.......

    Open

  5. More pics. I used a garden weed membrane to black out the inside then a breathable roofing membrane mainly to reduce condensation inside. I may eventually add ply to the inside walls.

    Also added mesh all round to keep out critters. Will add gravel etc for aesthetics and to weigh down the mesh along with bricks etc.

  6. I have come to the conclusion that to avoid these issues you need to make a screen which is higher than your eyeline in the direction of the problem. You have to accept that you see less sky but the observing is enhanced by avoiding constantly ruining your dark adaptation.

    I am building an observatory and can only look at a portion of the sky but the plan is that I won't be able to see any windows or lamps and therefore will enjoy less frustrating sessions cut short when lights constantly come  on.

  7. Hi Alan

    I have designed it to fit 1m long bitumen corrugated sheets which will overlap. 

    I have used decking for the floor as this can take water but hopefully it will stay pretty dry. My power will be disconnected in the morning after a session and I am visual only so no PC's etc.

    I can always redesign if needed. The roof has been the cheap bit so far.

  8. Some good progress today. Give or take a bit of adjusting, I have a working roof!

    It works as I'd hope with capacity for observing the main areas of decent sky whilst masking local and more general light pollution. The front flips down. The middle runs to front or back. The rear section is hinged.

    Here's some pics.

    I've raised a suggestion along this line in the newcomers thread. If there's interest, perhaps we could run a few visual challenges :)

    Speaking of challenges, I've heard imagers say on a number of occassions that one of the problems with visual observing is that under average sky conditions there are only so many targets that can really be seen. After a few trips around the Sun and looking at them a few dozen times, what then?

    So a question for longer term visual astronomers, what maintains your interest and mojo?

    Thousands of double stars, hundreds if not thousands of clusters, hundreds of galaxies, planetary nebs and perhaps a few dozen nebulae. Same as anyone really 😀
