On Thursday Nov 16th around 20.00 UT I was able to get a view of a couple of Arp’s in Pisces despite a poor sky especially poor that low to the south. Firstly I got Arp 68 a rather nice ‘spidery’ looking galaxy. Mag 12.7 and 2.5′ x 1.8′ in size. The Arp atlas describes it as “spiral with small HSB companion on arm”  the companion is really diminutive and would be a challenge in anything sub 20″ visually I suspect, unless under pristine skies. I managed to see it as a possibly detached region to the right of NGC 7757 and slightly brighter than the spiral arms. The sky was very hazy when I made this observation so I could have seen more on a better night, plus from my location it was low in the southern sky looking towards London! Sketch made using the 505mm + cooled Watec 120N+ camera.

Arp 68 a spidery galaxy

Next to be added to my list was Arp 284, suggested to me by Alan Snook an avid Arp observer from Kent. UK who had recently observed it and then found there was a quasar in the fov, although he could see it at mag 18 and I don’t know if I have caught it in my sketch either? Arp 284 is a pair of galaxies in Pisces, very close to bright star pisces 16. NGC 7714 is the RH galaxy and has interesting structure with a very bright round nucleus. With my set up it looked rather like the letter ‘G’. NGC is mag 12.5 and 2.2′ x 1.1′ and 7715 is mag 14.5 and 2.6′ x 0.5. Arp atlas says ” Double galaxies: infall and attraction”

Arp 284 and a possible Quasar in the sketch too!

 

The following night also looked very promising, it was very cold and looked lovely and transparent, I opened up around the same time as the previous night and soon had Arp 323 in Pisces on the monitor, as I fiddled with settings to try and maximise the image it began to fade! Within a minute it had gone totally, I went outside and the whole sky was fogged over, I was very disappointed, no sketch 🙁

By 4am the following morning I awoke to see a good sky with Orion splendid to the west. I rushed outside and decided that I would go for NGC 3628 the faintest and most extended member of the Leo Triplet which is also known at Arp 317. I had never sketched this well know galaxy. I got it onto the monitor, very large, extending right across the screen but the images was washed out, and then believe it or not, the sky fogged/clouded over very quickly and that was the end of that! I couldn’t believe it! Well I can really as that is astronomy in Britain, often frustrating.
