17.04.2020 Determining the optimum number of stacked frames per video.

*

Friday 17th Almost clear blue skies with bright sunshine. 

AWR's LST and parking position were accurate but the slew to the sun was completely wrong. By miles in azimuth and altitude. C-Du-C Skychart still shows positive west instead of negative east for my observatory site. It is clearly shown as east under Setup. But shows west on the Connect Telescope screen. Yet again AWR or ASCOM[AWR] had reversed the direction of Dec drive overnight.

I have been back to Setup dozens of times but it completely ignores what I do there. If I tell it to get the coordinates from the telescope it resets to latitude ZERO! Yet the telescope is showing the correct coordinates for its parking position on the IH2 screen. Tracking still keeps stopping and starting.

Once I was underway I captured the prom at 4.30 on the SW limb with 2000 frames. Then I ran the same video repeatedly through AS!3 but with different numbers of stacked frames.

Just to see the differences if any. I found the 100 of 2000 frames offered the sharpest detail. [Top right of the combined image left] The single image [at top right] is the larger version for comparison.

The seeing isn't very good today. With lots of thermal movement of the image on the monitor. Not surprising really as I am at maximum [camera] image scale while using the 2x William Optics Barlow and 640x480 frame size. 

Now I am moving onto experimenting with exposure times and Gain.
