Image with the ASI2600MC camera, cooled to -10°C, and the SharpStar 76EDPH at F 4.5, IDAS D1 LPS filter, 138x300s or 690 minutes of data at Gain 100. (Click on the image to enlarge)
While the clear nights were foused on imaging Mars, they also were a bit hazy and not that transparant. SQM value were at most 20,15.
Nevertheless the 76EDPH was running on the HEQ5 to capture IC5146 or the ‘Cocoon’ nebula in the constellation Swan. Some 90 shots of 5 minutes with the ASI2600MC Pro were taken, Gain 100 and Bias, Darks applied. Click on the picture to enlarge.
22 years ago, Mars was in opposition on 28/9/1988 and these are sketches I could make at the time with a homebuild 200mm Newtonian F6 with Lichtenknecker mirrors.
