M106

[ako]

a poor m106 image.

Last night it cleared earlier than expected. Dew was a major problem with as even the dew heaters couldn't hold it back.

Link is to an image of M106

A Magnitude: 9.10 barreled sprial galaxy in Canes Venatici.

also in the image are (top )NGC 4248 Mag 13.2 Sprial (image does not show structure) and (right) PGC 39615 A dwarf irregular at mag 15.2

Image has lots of bright coloured marks, i assume this is noise and could be taken out with dark frame subtraction?? if someone could advise would be greatful.

Image is a stack of 5 520 Subs. much detail was lost because of dew, and the eventual cause of the end of the evening even though the sky was still clear (with intermittent cloud passing over). wind has also given elongated stars.

Image also submitted to astrometry.net for blind automatic plate solving, results here: m106edit | Flickr - Photo Sharing!
