Super Duper Moon and other observations of November 2016

On the night of November 13 I was trying to take pics of the Super Moon rising.
I used my Nikon Coolpix S3300 camera on Velbon photo tripod.
While the Moon was low it was obstructed by distant trees.





Unfortunately ,when the Super Moon get higher , the sky was covered by cirrus clouds.
At least this provided  the show stage for a Moon Corona .











Two days earlier ,on November 10 I was observing the Moon to become better acquinted with her craters and mountains.
I used my ''Teleskop Service'' Maksutov Cassegrain 100 mm F/14 telescope.
Pics taken in afocal mode at 56x / Sirius Plossl 25mm.



Using the Coolpix S3300 camera at 16.5 mm focus and f/ 4.6 or 3.6mm aperture ,I got this picture of ''whole'' Orion constellation.

Home-made small telescopes on my ''Penelopa'' pipe mount

On my 1.5 inch pipe mount I use different small telescopes.To attache them to the mount I made three wooden clam shells and a dovetail adapter for the OTA of the Teleskop Service 100mm F/14 Maksutov Cassegrain.For now,my instruments include a 60x700mm refractor,a 60x800mm refractor,a 60mm F/5 RFT refractor ,a 45mm F/6.6 refractor and some more.I guess ,in time ,this collection will increase.

The corrector lens of the Mak.Some details visible of the non-metal dovetail adapter.
The 100mm F/14  Maksutov ,ready for observing.  8x25 mm finder.
Home-made RFT 60mm F/5 refractor with miror diagonal and 31mm Plossl. Visual field on the sky is 5 degree.
Another view of the 60mm F/5 refractor.The tube and dew cap are rubber armored.
The objective and tube of this refractor were part of a TCM 20-60x60mm terrestrial refractor.
Very bad image.The objective was optimized by my friend Silviu who is a lens wizard.




Home-made short 45x 300 mm refractor .The objective is an ex-military objective.
The cell of the 45x300mm refractor is adjustable.
My first ''long-range'' picture made with hand-held Coolpix camera and the 45mm refractor set for 10x .
