Question, is my pier out of level if I'm trying to PA (with asiair pro) and both directions are moving when I adjust the alt bolts? I can't get the mount polar aligned.
Mount neq6 pro
Pier mounted on a concrete slab
OTA c8 with .63 reducer
Camera asi294mc pro
Thanks in advance
After automating the dome on my Pulsar Obsy which has been a revelation, I have spent a considerable time researching how I could automate on what is a very basic manual shutter. The existing shutter slides on the aperture side of the dome and supported by two curved aluminium rods at the rear. What I will require is to create a runner system to allow the shutter to open & close smoothly, be aligned & contained to enable attaching a motor and drive system, thus allowing software automation.
The rollers are 30 mm dia nylon roller bearings, four per side of the shutter opening. This will allow the shutter to slide smoothly over the open aperture.
The rear side of the dome needed to be built up so I could affix tracks to enable the shutter to slide smoothly to the rear of the dome. This was relatively tricky as I had to build rear track support blocks to line up with the existing shutter. I plumped for wooden supports as I had to mount the on a sloping curved dome and as they had to be mounted vertically, creating some rather complex compound angles and curves. These were bonded in place and further secured with stainless screws from within the dome. Then having formed the arc in which the shutter will run I attached UPVC strips to complete the assembly. The sides will be cladded with UPVC.
The calculations had to be quite precise as I didn't have much breathing space
To be continued...........
I have already earlier written an article about the old observatory at Stockholm in Sweden where I live. Only 30 minutes away from my home by the subway. A friend to me, Nippe, told me that he had written an article about that observatory's history. I got permission to use it on my homepage. I have translated it to english (not perfect but I hope you understand the information) and implemented it among my earlier photos from the observatory.
Nippe's history article is very interesting, a lot of information about the observatory that I wasn't aware about.
Enjoy reading !
