    Warm room ventilation

    In my observatory there is no door to the "warm room" section - yet it does keep the chill out and cuts any wind down to more or less zero. Once I'm gone the air can circulate throughout the building - there are plenty of gaps around the sliding roof and I have never noticed any condensation inside the observatory. I suggest you simply leave the warm room door open when you are not using it.

    First Moon shot (for years)

    A lovely sharp image - you've not lost "the touch"! Just a suggestion - instead of wavelets, try deconvolution. imppg will find it. Have a play - I find it far easier to use than wavelets, and it gives results that are at least as good!

    Multiple channels - deep sky stacker

    If I recall correctly ('tis a while since I used DSS!) you put all the calibration frames and first set of lights into the first channel and then just the next set of lights into channel 2 etc DSS uses the one set of calibration frames for each channel.

    The Moon 10 February 2019

    I've been fighting the big mosaic below for over an hour and have finally given up! Simply not enough overlap to get the southern tip to stitch (with several different bits of software) as well as the missed a bit! Same details as above but a 2.5x Powermate used. 14 panes (13 actually ) in the final image. Worth clicking through to full size though:

    The Moon 10 February 2019

    My first Moon of the year (in fact my first night image since last November!!) Seeing was pretty wobbly but at lest I managed something. Four pane mosaic using the 120APO and ASI120mm mono camera. Each pane a stack of 100/1000 frames.

    Astrokev's ROR - The Build

    I use 12v LED strips on dimmer switches in the warm room - works very well. I also have a red bulkhead light. In the scope room i have a white bulkhead with the switch in the warm room. Dimmers are these: Dimmer switch (of which I bought four I think - useful to have a few spares! ), LED's come in just about every shape and size imaginable!

    Yup - Ebay is the cheapest by quite a way. As nigelg said leave a gap - about 1/4 inch (6mm) at winter temps of 1-5°C. If you don't it will buckle badly in the summer months. You can buy bigger "mats" of the stuff - look for anti fatigue matting - If you can find the right size you can create a floor covering with fewer joins in it. It also make a good lightweight dew shield material

    My own warm room/observatory window is a piece of clear acrylic sheet let flush into the wall. This has a sliding black opaque acrylic cover so that I can close it and keep the warm room lights on but the observatory dark - very useful. The sliding part, slightly larger than the window itself, just runs in a top and bottom "U" channel made from an aluminium extrusion from the hardware shop.

    What can I expect to see

    You have a decent sized scope there! I would suggest the Moon as a first object. You have a magnification of 1200/26 which is 46x with that eyepiece (focal length of scope divided by focal length of eyepiece). that will give you good views of the surface features. Most of the planets are not too well placed for observing at the moment (that will improve with time over the years!) . You could also look at some "deep sky" objects like star clusters (try the Pleiades!). If you download "Stellarium" (freeware) you can set it up to give you a view from your observing position for any time of night you like - have a look round and see what is there. The Moon is visible in the early hours at the moment but after 6th Jan (New Moon) it will appear in the evening sky after sunset. If you have a camera or phone you could try to take a picture by holding it to the eyepiece - with care the results can be surprisingly good. Please, whatever you do, DON'T try to look at the Sun - it WILL blind you!! After that stark warning the good news - you can buy a sheet of solar filter and make a holder to fit it to your scope so you could observe the Sun in complete safety! (it is a bit spotless at the moment as we are at the point of minimum solar activity, however in a few months (maybe by the end of 2019) activity should have increased enough for you to see some decent sunspots). You can probably tell that I'm a bit biased and enjoy observing and photographing our nearest star!

    5 mW Green laser pointers.

    In the UK (and Europe) 5 milliwatt lasers are essentially illegal (i.e. they cannot be sold). 1mw are allowed however there are strict controls over their use near airfields, pointing them in the general direction of people or planes etc.

    An excellent job!! Gina beat me to say put a bit of foam in that gap (Don't ask why I know that is a wise decision !!).

    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!!!
