This image is part of a very successful week.
I only invested a short night in capturing this open cluster. Thanks to the Stellavita, the session ran absolutely smoothly.
I mention this because the parallel imaging session on the APO, using its own setup, caused considerably more trouble and was a major reason why I decided to order a second Stellavita afterwards. This will allow me to image with both telescopes in parallel in the future, without stress and avoidable interruptions.
