NGC 383 Galaxy chain in Pisces


We had a cold frosty, and very clear. Early Winter sky on 2017- 12 -11 It was very welcome too. I was itching to finally capture some more ancient light, from the Whirlpool control room here in  Cheshire.

Because of the poor weather. I have not been outside since my last post. When I imaged the Cocoon nebula. How long ago was that!

It seems the British Weather is not getting better. I well remember times when, as a kid. We had cold frosty day's that lasted all day and into the night. That was the 1970s and 1980s.

How I long for a cold front to pass, with a lovely "High" that can bring frosty nights. For CCD imaging.

Onto NGC 383

Here is a picture of a very unfamiliar (to me) chain of Galaxies.

This is a chain of 12.5 magnitude galaxies in the constellation of the Northern Fish or "Pisces" I made a mental note to image this small group. After seeing other pictures, and finding reference to the galaxy group on the web.

It is a nice galaxy group that is very suitable for imaging, using my Altair Wave 115 EDT and Atik 428ex CCD camera.

NGC 383 is a double radio galaxy with a quasar-like appearance. It is listed in Halton C. Arp's 1966 "The Arp Atlas of Peculiar Galaxies.
Magnitude: 13.38
Constellation: Pisces
Apparent size (V): 2.34´X1.95´
Apparent magnitude (V): 13.4
Redshift: 0.017005
Distance: 209,000,000 ly; 64 Mpc


I have listed all the objects visible in the field, copied from "Observing Selected, Small Galaxy Groups" by Alvin Huey.

    Really nice image Paul. What was your exposure pattern ?

    Hi Mike,

    I took a 15 min exposure first to see how good my guiding was. Then settled on 6 x 600 seconds for the rest of this shoot. The 15 min sub showed slightly eggy stars.

    Then. During stacking, I added Flats and Bias frames.

    Processing in Startools and CS5.

Here we go again

Here is the first of many, I hope. Of my newly updated BLOG. The old one went the way of the Dodo, so I have been forced to create a new one. My older one. Pauls Deepsky Wanderings is still on here somewhere. But I can't access it so I can add to it. The weather at the moment is rubbish isn't it. I'm typing this whilst suffering from a bad cold. But hey. What the heck. It's Spring, yesterday in-fact at 11am GMT. Though out side. The weather feels more like late November than March 21st. And to cap it all we have Snow on the way. Now I am not pessimistic but. We now have that long awaited comet C/2012 L4 PanStarrs visible from the Northern Hemisphere, and guess what. Coupled with a big fat Moon and the day length increasing rapidly. The skies are still CLOUDY. Why does this always happen when, we have something interesting to look at? I have not been able to do any Astronomy now since the back end of last year. And like most off you. I am really sick and...

Good By Orion

Good evening "Skywatchers" Well, what do you know? We have had three evenings with clear skies and know Moon. Surely this has to be a record for British Skies and Astronomers. Last night I wanted to say farewell to our old friend Orion. So- I spent the evening imaging the area surrounding the three belt stars and Messier 42. The camera was my trusty Canon 1000D and the lens, my new Tamron zoom. I had that set to 140mm at F9. Here then are 34x3 minute exposures Un-guided.
