Some closeups on the lunar limb @99% Illumination

Really poor conditions for this last week for planetary/lunar observations- but still had that itch to look upwards. Taken on the 29th with a 99% moon, I concentrated my observations on the north-eastern and south-eastern lunar limbs that were still providing some interesting views. Here's a couple of features that I found interesting!

Gauss, Hahn & Berosus: Right on the northeastern limb, Gauss is seldom imaged, but quite large and an interesting site. Being affected by libration - from what I can research I think I may have been viewing at an unfavourable time but compared to some of the few other pics I've found online I've been able to capture most of it I think.

Boussingault: On the southeast limb, what struck me was the very interesting sight of another large crater that lies entirely within its outer walls!

Wish I could have got some more, but with only a few fleeting moments of good seeing, was kinda happy to walk away with anything tbh.

Thanks for looking!
