Hi all,
today I tried to get lucky with the following: C11(Aries D-ERF) + Quark + Player One 432 camera (9um) without a focal reducer, relying on very promising seeing forecast 1"...
I checked with the Solar Spreadsheet file, it shows critical sampling at f/42 and I obtained f/40 by fact, 0.17"/pix. Images looked oversampled and best record moments with about 1" seeing were not enough for such a scale. Or both.
I still decided to share couple of files, AR3040 with a pretty small spot and prom on SE limb.

They still look good Leo! Viewing them less than full size in the forum thread compensates for any apparent oversampling.
