    If you do wire up before cladding the walls draw a diagram and take some pictures as well - It's easy to forget where the wires are should you need to drill a hole later!!

    OSB should be fine - 18mm or more to get a solid floor. Get the "damp proof" stuff. No need to use marine ply - its far too expensive and your observatory will not be submerged for most of the time! If there is a little air circulating underneath then OSB will last for years.

    The Moon 18 November 2018

    First Moon picture since April - I'd almost forgotten how to operate the gear!! Usual set-up of ED120 AAPO and ASI120mm mono camera. Six pane mosaic each pane being 100/1000 frames. Stacking in Autostakkert3, sharpened in AStra Image and finished with Photoshop (stitching the mosaic and a tweak of curves and sharpening). (A couple of clicks required to get full size).

    Those creases will go og their own accord after a few warm/cold cycles over winter and spring. Looking good now!!!

    May I suggest that you don't oversecure your observatory. To the prospective thief it is a shed plain and simple and one decent lock should be enough for him to try his luck elsewhere. Any truly determined thief will get in no matter what you do!

    I would also suggest three - both for security and to help control things when you open and close the door on windy days. Don't forget that if you put the top hinge 6" down from the top of the door the bottom hinge goes 8" up from the bottom! It is an old carpenters trick as evenly placed top and bottom hinges just look strange - all an optical illusion of course. (I suspect everyone will be checking their doors now - honest its true!!!!)

    How about the "pins and holes" locking method Pins and holes As long as you have a drill you can make these easily enough - use bolts for the pins that only have partial thread, saw the thread off and file the ends "conical". Just one bolt to lock/unlock. Mine have survived several storms with no ill effects whatsoever. The roof is very solidly locked down.
  8. I've been using Baader film for several years now and it works very well indeed (The same piece of film as well!). You can make a holder and keep the whole thing carefully - mine is in a plastic box - ant it will last a long time.

    Daytime temperatures (13-15° C) - especially with the Sun warming the EDPM should be OK. I would suggest you put battens along ALL edges of the roof to have something to attach the EDPM to (sorry if you have thought of this already!). I would also suggest that you need two people to do the job - Mrs Bizibilder helped with my own roof. So much easier to have one person on each side. Also a long handled roller (sold for painting behind radiators) is really useful for getting the glue in places other rollers cannot reach. Also a spare clean roller helps to push the EDPM into close contact with the glue - but be careful not to stretch it. Talking of stretching - you may be better off gluing down on a relatively cool day, in the heat of summer the EDPM will have expanded quite a bit and will shrink as the temperature drops. Hope these notes help.

    Put an ad in SGL "wanteds" - there should be quite a few about as many folk upgrade or use piers.

    I used "Willow" which seems to blend in quite well.

    How to make bracket for stepper other focuser?

    I do mean box section. If you cut away part of the box you can end up with a right angled piece (or any other shape you can get from the original box shape - a quick sketchup shows what I mean:

    How to make bracket for stepper other focuser?

    Rather than trying to bend a strip of Aluminium (some grades will snap if you try!) get yourself a piece of box section (square tube - available on a well known auction site at reasonable cost) and cut a piece out to the required shape. You can do this either to a sketch or drawing or simply cut away unwanted metal until you have the required shape! A junior hacksaw should be adequate for this job. You can buy a file to get rid of the sharp edges and finally "polish" it with a kitchen scourer (the green type - works a treat on ali!!)
  15. Excellent image - as for the gaps you could try this software imerge This strips off the first frame of each of your videos and allows you to (manually) compose your mosaic. This is assuming you have a computer available as you collect your data of course. You can see how big an overlap you have which is useful, if you think things are a bit tight you can easily take an extra video of the overlap area just to be on the safe side. Never "missed a bit" since I started using it!!
