Virgo Galaxy Cluster – M86

Virgo Cluster centered on M86. 490×30 sec @ Gain 37, Offset 30, QHY183c cooled to -20C, UHC-S filter, TV-85 at F/5.6. SharpCap 3.2 LiveStacking w/dither.

This image is still in process.   It was not the best night for attempting this since transparency was poor at the time of imaging it.   Lots of LP in the 4 hrs of exposure accumulated and almost overwhelmed the dim galaxies.  The color was zapped out, so I took an image with only about 2 hrs of time and used it as color and the 4 hrs of exposure was used as luminosity.

M67 Open Cluster in Cancer

M67 Open Cluster on Feb 22, 2020. 50×30 sec @ Gain 37, Offset 15, QHY183c cooled to -20C, UHC-S filter, TV-85 at F/5.6, SharpCap 3.2 LiveStacking with Dither.

A quickie of M67.   Marginal conditions with seeing and only average transparancy.  But, you have to take what you can get in February.   Hopefully, we’ll get more than just one or two nights of good skies in March.

Crab Nebula

Crab Nebula on Feb 22, 2020. 122×30 sec @ Gain 37, Offset 15, -20C, QHY183c, UHC-S filter, Televue TV-85 at F/5.6.

Just over an hour’s worth of exposure for this one.   This was the 2nd object of the night, the first being Betelgeuse, which was only a few frames.

I had better conditions for this shot at the beginning of the session than later in the night for other objects.   Too bad it didn’t stay like that.

While shooting this, two older ladies came by to see what I was doing.   Interesting conversation, but I think I went right over their heads trying to explain a supernova remnant.   LoL!  🙂
