Astronomy Sketch of the Day

Goddess Selene showed me this beautiful old Lunar horizon landscape on the good seeing night on 15th 6. 2014.

I was very happy to see this view .

I opened covers of optics at soon after sun set , …. always the 35kg 18″ flat in front of the 13″ og cools slowly, the image saturn began to show encke minima when I started observing at 10 o’clark.
I was very tired then to give up observing as this 13″ never showed me a Lunar view that surpass 8″….. until now , I slept for 2-3 hours till 2 o’ clock ….. I woke up and again looked through the bino eyepieces.

The beautiful whole Lunar surface was there in incredible details that far surpass the 8″ even along the entire moon limbs… even in that low transparency night, then every skepticisms about the optical qualities shattered , vanished away.
The power of 13′ OG could penetrated twice times into the lunar horizon, so sketch span reduced from 70- 80 km of 8″ og to 30-40 km of 13″ og.

I was interested in water color painting when I was a high-school student and there is 40 years vacancy till worked again on this a lunar limb water -color picture.

…..Still work-able…, right?

Always clear nights, to all amateurs
