Testing the Sharpstar 76EDPH with the ASI183MM

It has been cloudy for the last months, this February New Moon was totally clouded out! With exception of lastThursday, February 20th: after an active rain zone passed through – with heavy wind and hail – the night sky cleared out.

After midnight till 4 am a clearance allowed me to test the setup. The test subject was the dwarf galaxy Leo 1 next to the bright Regulus.

This image was a quick test. Not only for the optics/camera combination, but also for the automation. SGP was used to automate, autofocus, and Solve& Sync. Where before I could not match the Solve coördinates from SGP back into Cartes du Ciel, this time it worked. The secret was to run both applications as an administrator. So both will connect to the EQMOD hub. Syncing in CdC (Manually) will update the EQMOD coördinates, hence also the SGP co*ordinates. And it works in both directions: Solve & Sync in SGP will update CdC. This is great!

I still had Luminance images also, but I did not add these: it were fuzzy frames and some reflections appeared. I suspect this Luminance filter is not ok.

This is a widefiled from Auriga with famous objects like M38 and the Flaming Star nebula. Taken on January 19, 2020: 62x300s or more then 5 hours exposure with the Nikon D750 on the TS76EDPH. Because the original file was too large, this image is a lower quality display. Please check Astrobin for a full view.
