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.

IC 1805

The skies on Thursday evening were for the second time. Very clear. This allowed me to use my Canon 1000D and 200mm telephoto lens, on the Heart Nebula. I shot 24 x 5-minute exposures for this nebula, through an Optilong UHC filter. The Heart Nebula (IC 1805) is an emission nebula located at an approximate distance of about 7,500 light years from Earth, in the constellation Cassiopeia. It is also known as Sharpless 2-190 (Sh2-190) or the Running Dog Nebula because, when seen through a telescope, it looks a bit like a running dog.  I have not seen or heard this name before. The nebula has an apparent magnitude of 18.3 and an absolute magnitude of 6.5. It is 150 arcminutes in size and known for its intensely red glowing gas and dark dust lanes forming a shape that resembles a heart symbol. The Heart Nebula forms a famous complex known as the Heart and Soul with its smaller neighbour Westerhout 5, also known as the Soul Nebula, which lies just 2.5 degrees to the southeast. ...

Weather.

You have to be, very thick skinned, to be an amateur astronomer in this country. I haven't done any visual astronomy or astro imaging, since the beginning of the month. We had a few clear spells at the end of  January, and into early February. But since that time. I have not seen a totally cloud free sky. This evening was supposed to have been, our society observing, session on Teggs Nose. That has been called off, or I should say rained off. Because of the wind and rain. It's driving me mad. Strom Doris, whizzed by last week. Sadly she took one young victim's life, who was in the wrong place, at the wrong time. Very sad indeed. Thankfully. Where I work and live. We had no damage. Although there were, at times. When I wondered. Should be working under all that glass at Stocks Lane. The environmental computer, recorded  a gust of 56 mph at one point. I hope the Lovell telescope wasn't damaged during the storms! On Wednesday we move into Meteorological Spring. ...
