NGC 672 in Triangulum

 This image is based on around 90mins of 114 s , gain 139, offset 21, exposures, all in luminance. Finally done some new flats, but moved the camera slightly when checking for dust, so still not the best.

NGC 672 in Triangulum


Interesting galaxy, plus  several small ones in the background.

Wikipedia: NGC 672 is a spiral galaxy in the northern constellation of Triangulum, positioned around 2° to the southwest of the star Alpha Trianguli.


This galaxy is located at a distance of approximately 23.4 megalight-years from the Milky Way,where it forms an interacting pair with the irregular galaxy IC 1727. In the neutral hydrogen radio band, a tidal bridge is observed between the galaxNGC 672 appears to be the more massive of the two, and hence IC 1727 shows more distortion from the interaction. Together they form members of a combined group of galaxies that includes NGC 784.


The morphological classification of NGC 672 is SB(s)cd, which indicates this is a barred spiral galaxy (SB), with no ring structure around the central bar (s), and moderately to loosely-wound spiral arms. In the visual spectrum, the galaxy appears symmetrical with clearly defined spiral arms.

Two Galaxies far far away

 Last few times I have ben concerned the mount was not accurately aligned, so the first thing done tonight was to check the polar alignment. I gave up using the polarscope and in the end used the Drift tool in APT. This seemed to work very well and thereafter  the     scope went to its target fairly accurately, with Sync being used to correct any slight errors.


I ended up looking at a couple of galaxies, one of which I imaged in Jan this year. Next job is to redo the flats, those dust bunnies are still there!


IC2166 in Lynx

IC2166 is a barred spiral galaxy about 120 million lights years away!

NGC 2403 in Camelopardalis

NGC 2403 (also known as Caldwell 7) is an intermediate spiral galaxy in the constellation Camelopardalis. It is an outlying member of the M81 Group, and is approximately 8 million light-years distant. It bears a similarity to M33, being about 50,000 light years in diameter and containing numerous star-forming H II regions

Grainy Mars

 Too pixelated but hey ho




Some galaxies and an Open Cluster

The galaxy images are in mono. I need to take some new luminance flats as there are dust bunnies showing!  

NGC6688 is a galaxy in Lyra, with some friends.






NGC2300 is a galaxy in Cepheus, interacting with an elliptical galaxy.




M34 is an open cluster in Perseus.
