ARP 282 on a windy night

The trouble with wind is that it shakes the scope not allowing the camera to exposure for very long without streaking on the screen, in other words pretty useless unless something is very bright and the camera can grab a good image quickly. Last night was blowy, however I luckily went for an Arp in Andromeda that turned out not to have too much faint detail so a relatively short exposure camera setting got me enough detail to be quite representative of the object!

Arp 282 in Andromeda

Not the most exciting of the Arp’s. The larger NGC member is mag 12.4 2.7′ x 0.7′ and the tiny IC galaxy mag 14.7 0.8′ x 0.4′. North is down in the sketch. Made on 12-11-17 using the 505mm mirror * cooled Watec 120N+ video camera.

Arp 212 through the haze

Monday evening, cold but hazy around 6.15 UT I locate Arp 212 close to Peg 68 which made it easy to find. I take a while to adjust the monitor & camera settings to get the best contrast and resolution. I then ‘freeze’ the frame and go in for my evening meal at 6.30 🙂 Well I have to keep the good lady happy 😉 I get off lighter than usual with the washing up and get back out to the obsy and make my sketch. Not the most exciting of galaxies but there is something going on, here is my sketch and my notes from the Web Page :

Arp 212

Within the Square of Peg in the same fov as 68 peg we find Arp 212 NGC 7625. listed by Halton as showing “irregularities, absorption and resolution” “Narrow chaotic absorption tubes across one end” I certainly saw mottling and distinctly dark regions within the galaxy. As an aside I noted that the 2nd brightest star in the field (102 peg) was distinctly ‘egg’ shaped with E-W elongation, I suspect this must be a double just on the verge of resolution in my 20″ set up. Sketch made on Nov 7th 2017, using the 505mm mirror and cooled Watec 120N+ video cam. Sky very hazy. N is down
