Dec 29, 2020 - Lunar Blue Lake (Ina)
There is a nice story to that, before the end of 2020 I watched a YouTube about a guy trying to image a crater on the Moon called Blue Lake, to be honest I thought that it is not realistic as he was trying to be funny, but by the end of his video he managed to image a blue spot on the Moon which got me very curious.

I used my SkyWatcher 180Mak, TeleVue 2.5x barlow, ZWO mini filterwheel and ZWO ASI174MM camera, I captured 10,000 frames video for each Red, Green and Blue filter and stacked only 4% of that in AutoStakkert3, used PixInSight, Photoshop and Luminar4 to process the final image. I've also used a new technique to sharpen the image called APF-R which I found very interesting.
