Managed to get out and try my new 742nm IR pass filter last night. I’m following in one of our Club members footsteps and want to try and image all the Lunar 100 objects. This is No1. The whole caboodle.

I’ve never really looked at a full Moon quite so intensely as even with an ND filter, it hurts your eyes and generally at this phase never looks that interesting. However, the length of the ejecta material coming from Tycho going just past Mare Nectaris is huge. Using the measure took in Virtual Moon Atlas, this comes out at 1574Km long.

The other stand out features are the intricate web of ejecta from Copernicus to the North and the smaller companion Kepler to the West.

The image above was captured using Sharpcap’s Planetary Live Stack mode. For EAA this has been a revolution as now we don’t have to capture a .SER file and do all the Autostakkert and PI processing post the observation. It’s now all now done live an at the time.
