23.4.20

23.04.2020 An early start? Nice prom at 10 o'clock NE.

*

Thursday 23rd 38F and bright sunshine. 

7.00 The dome is already sunlit. So I might as well start early before the promised cloud arrives. The seeing wasn't great when I started at 8.00am recently. Perhaps it will be better today? 

7.23 45/42F. First capture of a superb prom at 10 o'clock on NE limb.

7.44 48/45F Added the 2x WO Barlow for a close-up.

8.04. More detail but too hard on the processing!

8.30 Tried to be more gentle with ImPPG.


I had noticed a drift in the tracking and had to adjust the mounting alignment. The RA drive motor housing was jammed against the pier top plate. So I relieved the plywood top plate and then was able to rotate the mounting further towards the west.

A screw adjustment in azimuth would be better than my 4' length of scaffolding pole! Another roundtoit!

10.21 Swapped over to the Lunt B1200 BF. Interesting surface markings in NE. Possible filaments?










And finally, another shot of Venus with the 2x Barlow through the 6" H-a telescope.
