Playing with white balance

Canon EOS 5D mark II, Samyang 8mm f/3.5@f/5.6 ISO 800 30s

Some progress

Finally I was able to balance and align EdgeHD 800 on NEQ6 Pro. After that I ran over twenty vcurves with FocusMax and finished by measuring focus offsets for photometric UVBRI-filters.

EdgeHD 800 ready to go:

 Reducer 0.7x, FLI PDF focuser, SX Mini filter wheel with OAG+Lodestar and SX-694:

Now the only thing which is still missing is clear sky without any clouds...

Very very wide angles

Lack of clear skies has forced me to dig camera bags and start thinking "How about taking pictures of different clouds?" ;-)

Two Samyangs:

8 mm fish-eye produces circular image on full frame sensor:

14 mm is quite wide angle too:

Fast and wide 24mm f/1.4 is best for Auroras:

HAT-P-37 b

HAT-P-37 is a star far far away (over 400 parsecs) and has got at least one planet orbiting it. HAT-P-37 b is "hot Jupiter" very near it's host star with an orbiting period under three days only.

MaximDL astrometry measured RA 18h 57m 11s and DEC +51° 16' 09"

The Sky X and EQASCOM were not so precise with the position:

Baader UBVRI-filters for photometric measurements:

Just for fun

Purchased this jewel as new just for fun. 150mm f/2.8 is quite suitable for certain wide field objects. Will try it with D7100 body and CCD-cameras.

Binning 2x2

When binning 2x2 you get your data four times faster. In other words for example a single 2x2 binned 5 minutes exposure equals unbinned 20 minutes exposure. Here is an example taken with SX-814 CCD-camera (only 30 five minutes 2x2 binned exposures were taken using 3nm ultra narrowband H-alfa, O-III and S-II filters):
