Two planetaries and a Whale

Both planetary nebulae are way up north. NGC 1501 is in Camelopardalis. I actually shot the OIII for the nebula last year, but I wanted RGB for stars. I just wish I was better at keeping star colors. I’ll figure that out when I move to PI, I hope. This PN is bright and detailed, but for some reason doesn’t attract many imagers. This one only needed 5 minute OIII exposures.

IC 289 in Cass is tougher. It’s fainter and a bit smaller, but has some interesting details. If 1501 is off the beaten track, IC289 is in the middle of nowhere. I found only one amateur image of it, and that’s a very early one by Adam Block from Kitt Peak. This one needed 20 minute exposures, both Ha and OIII.

And last is NGC 4631, again from last spring. I keep messing with this one, and each time I look at it I see something wrong (like just now), but I have to move on! This one is straight LRGB, through pretty heavy light pollution.

These are all shot with a CPC1100 and SXVR-H694 (winging its way back to SX for repair as I write this) from my little backyard dog-servatory.



Excellent images, Kevin.


Really excellent work. That is really impressive at that focal length.


Fantastic Kevin especially with CPC1100. I could not always get perfectly round stars consistently with my former CPC0800.


Thanks, Mark, Ken and Peter. Peter, I can’t say I get round stars all the time. Poor seeing still seems to throw me off. But it’s hard to complain about a scope/mount combo that gets me these results for less than $3K. Planets, too - it’s out there imaging Jupiter right now. While the moon is out and my SX is in England maybe we’ll have some good seeing for Jupiter to keep me busy. :smile:
