Anywhere Is: W

Constellation Cassiopeia fits just perfectly into the FOV of my 60 mm. And the haze was on my side this time making bright stars even more prominent.

 

It was cold and damp night, but it was a second starry night since the end of August.

 

Aquisition time: 13.10.2013 around 00:10 MSK (UTC+4)

Equipment:

Canon EF-S 60mm f/2.8 macro USM lens and Baader Planetarium 2" UHC filter mounted in front of the lens via step-down ring attached to Canon EOS 60D running Magic Lantern 2.3 firmware override riding on Vixen Polarie tracking platform over photo-tripod (alltogether codenamed "Anywhere Is, SWANS configuration").

Aperture 21,4 mm

Focal length 60 mm

Tv = 30 seconds

Av = f/2.8

ISO 2500

Exposures: 10 (plus 5 dark frames and 5 offset frames plus 4 fake flat-field frames).

Processing: Images were converted to 16-bit TIFFs in Canon DPP and outputs were fed to DSS.

16-bit stacking result was processed in Photoshop. Image was scaled down √2 times.

Note: THEY can't deliver me the polar scope since the beginning of June. It's a conspiracy!
