NGC188 (C1)

2020-04-07T21:23:16+00:007 April 2020|Caldwell, News, NGC Winter, Open Cluster|

Never noticed this one before. Very close to the pole so easy guiding as nothing moves very much round there.

M44 Praesepe / Beehive cluster

2019-01-30T14:43:15+00:007 January 2019|M31-60, News, Open Cluster|

Poor night of transparency and seeing so just got this in the passing. Lots of sky fog that got processed out.

NGC 2264 Christmas Tree Cluster narrowband

2019-01-30T13:16:31+00:0030 January 2019|HOYS, Nebula, News, NGC Winter, Open Cluster|

After a HOYS-CAPS session added narrowband. Rat’s head in there?
No more MPCC and stars are much sharper at the edges.

Bad planning in that the object went behind the observatory roof after only 5 sets of exposures. Not great but better than expected though.

Good quality flats make such a huge difference. Much easier to process, especially when using the reducer.

NGC 663 (C12)

First chance to try out the new 460EX properly.

A “mucky” night with low transparency. Lots of star bloat but the camera has almost no noise at -10C. Processing still needs some work. Too many very red stars. Could be caused by the DS filter?

Not transparent enough tonight to image any galaxies (tried M33 but the image fogged after 2 minutes) or nebulae so a new open cluster for me.

I came across this one by accident. A lovely open cluster. 

NGC 7789 is an open cluster in Cassiopeia that was discovered by Caroline Herschel in 1783. Her brother William Herschel included it in his catalog as H VI.30. This cluster is also known as “The White Rose” Cluster or “Caroline’s Rose” Cluster because when seen visually, the loops of stars and dark lanes look like the swirling pattern of rose petals as seen from above. Wikipedia

Some slight elongation of stars at left side is due to camera alignment and not coma (which has been resolved by the MPCC).
