We have been spending part of each year in Strasbourg since 2015 and, since 2016, while here, I have been imaging with a beautiful little Celestron 127SLT Maksutov-Cassegrain from our third-floor apartment window. This involved turning off the radiator and capturing out of the window over light-industrial firms and floodlit building sites, with folk wandering about in the flat overhead causing the floor to shake at critical moments.
We are now selling up and will be spending more time in Canberra and so, with a heavy heart, I have sold this scope to a friend who collected it today. It helped me to keep developing my imaging skills even when away from my 8SE and C11 in Canberra. It also allowed me to participate in the various CN "Small Bore Challenges", which are great fun. I took it to Star Nights and have had queues of people gasping at Saturn (or maybe they were gasping at my French accent!).
I thought I would post here what I consider my best images with this scope as a sort of affectionate valedictory. I will really miss it!
If you are thinking of starting up in planetary observing or imaging, the 5" Mak-Cass scopes (there are various on the market) are excellent value for money I think. The optics are very stable - in fact I don't really know how to collimate it! And it is easily transportable. For moving it around the flat I leave the imaging train in place but can still lift it, tripod and all. I added a JMI electric focuser to assist in imaging.
Looking forward to getting back to Canberra and the C11 late in October!
