NGC 4565; Needle Galaxy

This winter has been awful for astrophotography... Last clear night was about three weeks ago and after that has been snowing regularly. Here in southern Finland is now over 80cm of snow.

This time I changed my Meade's focal reducer to Celestron's f/6.3 which has much greater back focus. I put the distance to 105mm which gives me 1325mm of focal length (pinpoint) and an f/6.5 scope. And no problems with OAG picture anymore, great!!

This faintish (mag 9,5) galaxy can be found in constellation Coma Berenices and is about 20 million light years away.

Picture is taken with Celestron's C8 SCT f/6.5 and QHY9.

Exposure: Luminance 9*10min (bin1*1) and colors 8*5min (bin2*2).
