Photo description / processing

One of the first attempts at using a "real" mount with tracking and guiding. Processing is minimal - rotation, cropping, removal of gradient light pollution noise, removal of green noise, histogram stretching, black balance. Camera cooled to 0 degrees. Didn't like the stars (puffy with rays on one side), quite possibly it's an issue with the telescope optics or a problem due to noticeable vibration from the camera fan. Also visible is the effect of star trailing at the edges of the image. The telescope is used without a field flattener.

30 m

Test of the new Askar FRA300 Pro telescope. Half an hour of total integration with different exposures. The best were 60-second subs. Processing is minimal. Image quality is, of course, better than the RA80ED. And the field is wide and flat.

To photo #1, I added a couple more hours of integration. The processing is the same. The obvious effect is that the quality and detail of the image have increased. What turned out worse is the stars, they are bloating further.
