Sinus Iridum
Hello all,
Well I have a (temporary) piece of concrete under the shed roof to set up the scope. I can only see 60 degrees up in the east which is better than nothing!
Sinus Iridum taken on the 14th September. The interesting thing about the two promontories - Heraclides and Laplace - is that they differ in height dramatically. Laplace is over 3000M high while Heraclides comes in at 1800M. This goes to show how "unlevel" craters can be. Also possibly explains why half the thing is missing under lava.
The two wrinkle ridges which look like waves about to break on the inner shore of Iridum are high also. The ridge below Bianchini boasts a spot height of 360M - a fair hike for any astronaut even at 1/6 G.
3000 frames stacked in AS!3 and processed with Registax, Focus Magic and Astro Art. Celestron 14"HD, ZWO 178mm camera, Red filter.
