So I just recently got myself a new toy, a daystar quark -chromosphere. While it works flawlessly on my 115mm triplet I would preffer not using it for solar imaging because I don't want the intense sunlight damage the optics in any way possible. I will use my 80mm doublet instead but I want to do some high resolution imaging and I have seen people taking great images using F8 120mm achromats like the celestron one.
I have been looking everywhere and all of the 110 - 150mm ~f8 achromats are either sold out or not in stock for another ~2 months (bresser). Besides that I searched for used ones and no luck. If there is one available I want it to be in Europe.
Are there any other options or do I just have to wait a few months and meanwhile check the market every day?
