Fullerscopes Telescope Mountings

This blog has become my ATM design, build and imaging diary. I have recently built several new telescopes, a large equatorial mounting and a raised 10' [3m] dome on an octagonal building. Be aware that I deal with building solar telescopes. Which are potentially VERY dangerous! I can accept NO responsibility for any action not directly supervised by myself. You are NOT entitled to blame any other person for your OWN lack of skill or ignorance. You copy me at your own peril!

12.10.2021 Imaging AR2882.

*

Tuesday 12th 39F, promised to be bright and clear.

9.56 43F. Imaging. Cold in the dome. I have my scruffy old down jacket on for the first time this year. The mouse is misbehaving despite new batteries. The seeing is very soft again. I have checked the optical train for condensation. It looks clear when I peer through the objective. Just the inevitable dust on the optical surfaces.

The image shows the view inside the OTA. The multiple reflections are from the Baader D-ERF. The bright, central reflection may be the PST etalon or the Baader 35nm H-alpha filter.

10.14 First [recognizable] image. Etalon sweet spot problems. Lack of detail.

10.22 Slightly improved image after more etalon tuning. Still very strange. It looks over-sharpened but isn't according to the settings.

10.30 More thermal agitation now. Etalon tuning still poor. Dark band and light areas. The AR deserves better than this.

10.45 Detail improving but uneven brightness across the frame.

11.00 Seeing has steadied with improved detail. Still can't find the even lighting setting for the PST etalon.

16.17 The only image I bothered to finish processing in the afternoon.
