Imaging Session – 1st Dec 2021

Adjustments made to the backfocus on the WO Z61 with the Z61R Reducer – now a bit closer to 55mm but still a bit out. I decided to have a go at NGC 6969 West Veil Nebula.

Backfocus of 55mm from Flattener to camera sensor

The stars at the edges are still a little elongated but not as bad.

Same night took some frames of the centre of IC 1805 Heart Nebula with the Esprit 120 and the ASI 533 (and the L-Extreme broadband filter).
