SharpCap direct view for fits file with ALTAIR 294C
Posted: Mon Aug 14, 2023 12:06 pm
Hello ,
Two night ago I tried to capture M51 galaxie with my Newton 1200x250 and Altair Camera 294C in RAW 14 and Fits file format. I was sure that I was aligned to M51 , that I saw before monting my camera with an 36 mm ocular. I tried first with 60 sec exposure with a gain of 1000 , and i didn't see the galaxie. After several exposure I needed to move to 5 minutes of exposure to see in SharpCap window the galaxie. My concern is that when opened the fits file with 45 sec exposure and 650 gain with Siril the galaxie is clearly visible. Why there is a such difference between SharpCap view and Siril for a fits format ? Is there a particular sharpcap setting to see fits picture in direct view ? Trying with PNG format the issue was the same
