Comparing it to my own setup, also a Photon 150 mm with the same corrector, same filter, and same camera. I don’t see any difference.

There’s probably no point in going for 200 mm. The 150 mm fully captures our atmosphere at 4‑minute exposures. I like your images. I think we bought that 0.75× corrector on the forum around the same time. It’s a 100% keeper.

Hello. On such objects, there won't be a big difference; the 200 only gains a bit in resolution on small details.
I had the PS 150 f4, a great telescope—I rushed into selling it.)
