  1. ‘The heavens were glorious with stars.’ Headlines: deep space exploration, challenging science missions to the Moon, Mars, Venus, Mercury. Celebrating all the achievements of 2019 - 2021. Any system on the Earth orbits is under certain difficulties and threats due to debris and launches boom, creating even more. Any stargazing from amateur to most important observatories is blocked to a certain scale. Pioneers go with maneuvering engine designs (for instance, Starlink reported more than 1000 maneuvers for the ‘first bunch’ launches). Nevertheless, the space industry itself is doing its job, most of the time looking down to the Earth with support. A U.K. company Skyrora (https://www.skyrora.com/) third-stage engine onboard a vehicle is capable of delivering satellites to destination orbits. The vehicle is able to perform a number of maneuvers in space, passing the space junk and satellites that are already in their orbits. Would it be an option for getting our telescopes to a new level? For my personal perception, the sky's observance comes from the rare lucky alignment of all the uncertainties with weather, time, obstructions and so on.
  2. From the data tables it is visible that mean counts are somewhat more with RBI for both 1Nhz and 8MHz compared to no-RBI with largest exposure. Let’s look at the minimum values (without zeros): 8MHz RBI (274) is more than doubled compared to others (the same 103 and 127). Maximum values: all of them about the same. That tells the RBI functioning in general and your particular case. Generally, RBI doesn’t affect the observations as the charge captured in traps slowly disappears and the shadow image fades. RBI causes ghost imaging. However, the final banding comes from using a RBI clearing flash. Actually, intensity of RBI on long exposures are only a few electrons or tens of electrons per pixel, which is typically below the influence of other disturbing effects (e.g. high clouds). For certain cameras and setups RBI preflash might be turned on, but not in your case, I would say.
  3. Hi, Christer, everybody! I am new here, but I am with strong background (hopefully enough to be useful). Please take me to the interested list. Starting from tasks is the way I like. Thank you.

    Hello, ASA!

    Dear community, It is my pleasure to join. I am a passionate photographer for many years with some background skills and knowledge. I would be glad to get new knowledge here and share my experiences. Looking forward to become a contributor here. Lariliss
