ORION AND FRIENDS ARE BACK!

I did a quick run of the EOS 90D (moded) with Samyang AF85/1.4 shot at f1.4 and ISO2000 ... untracked. It's been quite some time since the sky cleared, even for these shots clouds moved in quite quickly after only 20 shots. Purple fringing on the AF85 is quite strong as observed on previous occasions.

Since 90D is a cropped body these shots below are effectively 85x1.6mm focal range ie. 135mm. My Samyang 135mm would be changed to 216mm focal length, and the Askar 200mm with light pollution filter would be 320mm!!!

This will be my reference shot : Shot on my Sky-Watcher star adventurer tracker with Canon 5D Mk4 and 24-70 lens. Around an hours worth of images combined to increase the information captured, then stacked together in DSS and processed in Photoshop.

NIFTY-FIFTY : CARL ZEISS JENA TESSAR 50MM F2.8 (2ND UNIT)

 Received my 2nd unit Carl Zeiss Jena Tessar 50mm f2.8 from the UK yesterday and decided to make a few shots just to confirm all is OK. This unit costs me GBP40, doesn't look much different than the earlier unit with the exception of the color of the distance scale, orange on this unit and green on the earlier one. Both are "MC" for muil-coated.
