Still plugging away at it here and here's a few more snaps.
Got the Entry door done so we have lockup
Screwed a hasp and staple onto it to stop it blowing open in the wind. I'm trying to find a rod type lock that pushes a rod up and down, through the door and into the frame. Bought some rubber flooring and got the first 4 bits in.
Spent a fair bit of time trying to get the dome to rotate beter than it is. Looking at the wheels, there is already signs of wear on them and about 75% of the tapered wheels contact the dome so the dome is squashing the wheels somewhat. Also they don't have bearings just bushes and they are prone to slide on their axles and bind. All this tends to make the dome slide at times and bind up on the guide wheels.
I've been round to the metal benders and they can bend me a 30x30x3mm alum L for about $150 and I found some ball bearing U wheels to suit so I might upgrade the ring. I did do a first light with the 10" newt on M42 and found I had to move the dome every 15minutes or so or the guide star would be lost so automation is really a must have.
I've added the M42 image, which is just 5x5minute subs, Ha binned x1 with O3,S2 binned X2. Spent 2 minutes combining and curving this one but have some shorter shots to overlay one day. No calibration files used at all and I think I have these 36mm baader NB filters in the wheel back to front. I'm guessing the mirrored side should point to the scope?
[edit]
I forgot to mention that I used up all the left over foam by lining the lions share of the wall cavities including the door. Three remain unlined, they face the garden and fence so won't receive sunlight and will be used for mounting power supplies etc. I put a digital thermometer in there this arvo and it was 1 degree cooler than the ground floor of the house, however the obs is still vented through the slot between the dome and the wall.
