M35 wide field
The wide field streak continues uninterrupted, now that the weather is finally giving me a well deserved break. so here I present you with my take on the area surrounding the open cluster M35, in Gemini.
M35 is 2800 light-years away and it spans 28 arcminutes, i.e. almost the size of the moon.
This image is the sum of 51 3-minute shots, properly calibrated with dark and flat frames of course.
You can see details cropped to 100% here and here.
A keen eye will also notice NGC2174, an emission nebula associated with the star cluster NGC2175, visible in the picture left (south) of M35. Mental note to self: image that nebula with the 80ED refractor once the guider camera is repaired.
