Thank you for the information and advice, and even a compliment! I appreciate it very much. I will look into the WO rather than a new lens purchase.

Hello! I am just beginning my astro photography journey and am wondering what advantages a WO Z61 (or similar) would give me over a 100-400 f5.6 telephoto lens? I have used this lens and gotton fairly good results, with post processing in Pixinsight. I have read and seen a lot of reviews of the Z61 but other than field flattening can’t really tell if it is worth the investment. Any help, or even suggested options would be greatly appreciated! Attached is my version of m42 taken with this lens and processed in PIS. I am also still trying to understand the processing workflow so be gentle with the criticism. Thanks and clear skies from seemingly always cloudy Sweden!
