What the heck was that?
« on: June 24, 2017, 09:02:40 AM »
At the risk of bringing ridicule and shame upon my head, I want to relate an observation I made last night while at Fremont Peak, because I can't figure out what it was.

I was using my 20-inch, around 2:30am, with Cygnus at zenith.  I was poking around the Cygnus Cloud observing a variety of objects, when I come to STF 2609.  Instead of the fairly close pairing I expected, I see two streaks of light, each maybe 10" long, each with bright small disks on the ends.  They looked like staples.  They were parallel to each other and N-S, one was a little dimmer and shorter than the other, and each had a dimming along the major axis between the points at the end.

I thought it was some kind of optical defect, but the streaks remained at all powers I tried (205x, 333x, 533x, 667x).  Other stars were points of light, even those of similar magnitudes.  I took a few minutes break and came back to it: the same.  Seeing was very good; just a few minutes before I made a clean split at 333x of B1289, which has a 0.7" separation.  Transparency was average; SQML was 21.2

STF 2609 is 6.69/7.64, 1.9", PA 21°.  I would say the streaks were of similar brightness, separation, and in the correct PA.  But why in the world would they be stretched out so?

If only they'd moved, Mark. The staying-put part is the real head scratcher.
