Mare Crisium, Langernus, Petavius & Furnerius (21/11/2021)

[rob_r]

Hi,
Another decent evening last weekend, I captured Mare Crisium, the Sea of Crises through the Langrenus and Petavius craters down to Furnerius crater, the Great Eastern Chain along the terminator. Even picked out O'Neill's Bridge. Taken on the evening of the 21st November from 9pm to 10pm, one day (I think...) after the full moon. Covered the notable mares in this area of the Sea of Crises; Sea of Tranquillity; Sea of Nectar and Sea of Fertility. Just a hint of Rheita Valley at the very bottom right. The 2.5 Barlow was reflecting light internally onto the sensor so didn't add to the imaging train for this session.

Filter: Baader 685nm IR pass

Stacked best 25% of 3000 frames, wavelets applied via Registax 6, level adjustment and unsharp mask applied via Photoshop. Placed five images together into a partial mosaic in Photoshop.

Thanks for looking.
