Moon 41%
Moon is 41% and moderate seeing. Picture taken in prime focus with Nikon D60 on Dobson Orion XT12". Editing completed using CS4.
Very Cold Observation testing SE 9mm 100° Ar purched ocular
Clear sky and moderate seeing this evening and very cold with temperatures up to -8°C.
Observations done using Dobson OrionXT12 and my new Ocular. This is a Scientific Explorer 9mm 100° wide angle, argon purched and waterproof consisting of 9 elements. It was bought directly from Bresser in Germany.
Observations done on M1, M35, M36, M37, M38, M42, M43, M81 and M82. Also the moon was with 41% a perfect object for testing. I'm very happy with my new ocular and the starclusters are showing up very bright and sharp. The 100° wide angle and field of view makes it necessary to have your eyes travel around to see all the details. Very good quality, good contract and bright immense view. The ocular was delivered safely in a nice big box without any issue.
