4 Members and 2 ex-Members travelled to the Kelling Heath Star Party, this star party has notoriously poor weather, but on this occasion we were blessed with reasonable views on Wednesday night and clear skies from dusk 'till dawn on Thursday Night, Friday Morning.

Many, many objects were observed with Keith's 10" Dobsonian and Simon's 12" Truss Dobsonian, Julian and another Simon both allowed us to view objects with their 20" Dob's.

Apparently the food was epic...

DSLR Cooler box

[/et_pb_text][et_pb_text _builder_version="3.21.1" z_index_tablet="500"]

A DSLR, ideally one that has been modded to remove the filters is an accessible way to begin imaging, and I have successfully imaged using a 'full spectrum mod' Canon 600D for many years.

Unfortunately these cameras are not cooled and the sensor temperature (measured by the camera) runs about 15 degrees above the ambient air temperature. You can find cooled DSLR's but these are very expensive, however by simply putting the DSLR into a box and cooling the box using a peltier cooler it is possible to cool the DSLR without any modification to the camera, delivering measurable improvements in noise.

Parts:

All parts are readily available on Amazon

Water proof electrical case
Expanding builders foam
Peltier cooler

The approach is not unique, my cooler box was based on the design here

Open Cluster, M46, NGC2437

Messier 46 also known as NGC2437 is an open cluster discovered in 1771 by Charles Messier. it is a very bright and very rich open cluster of about 500 stars and as a bonus the planetary nebula NGC 2438 appears to lie within the cluster near its northern edge, but in reality it is most likely unrelated.

If you are looking at M46 why not also have a look at M47.which is only about a degree west of M46, so the two fit well in a binocular or wide-angle telescope field.
