Ha Full Disk 1st October

Ha FD DS50 2x cemax zwo183mm pre transit bw The sun gets ever lower in the sky but clear skies meant I managed a quick full disk in the afternoon. I was keen to try out my new Beloptik ITF filter on the BF15, and are pleased to find it has higher transmission, with exposure time of 5ms compared to the usual 6ms. The disk was taken with the double stacked 50mm setup, 2x cemax barlow and the ZWO183mm camera.

Sunday Sunshine 26th June CaK Selection

Conditions weren't supporting the largest apertures, but I was able to get up to 80mm for the closer views. Very pleased with how the zwo183mm performs at CaK wavelenhgths, both full disk and for closeups using ROI.
