It's "June Gloom" season here in LA, when morning clouds give way to partly sunny afternoons, followed by clear evenings. And then at some point in the night the clouds return. Lately they have been returning around 11pm, earlier than I'd like but happily the seeing has been pretty good, and that got me thinking about close double stars. On Friday I made a list of about a dozen 1" doubles and in the 60-90 minute window I've been getting to observe I tracked a few of these down. I'm not quite done with my list yet, but since it's supposed to be pretty cloudy the next few days I thought I'd do a report and then add to the thread once I wrapped it up. I've been using the 12" Meade LightBridge truss dob I bought used a few weeks ago.
My strategy for is simple:
First the finderscope. Then 64x with a 27mm Panoptic. Then the Zoom for framing. Then 350x in the Nagler.
First up: Draco, and couple of vertical pairs.
STF 2054 (6.2, 7.1) // 1.0" @ 352 ... I could tell it was a double but it looked kind of smushed, so I'm going to return to it later this week when the clouds clear. I'd like to get a clean split.
STF 2118 (7.1, 7.3) // 1.1" @ 337 ... this one split cleanly
STF 1734 (6.8, 7.3) // 1.1" @ 173
BU 114 (8.1, 8.2) // 1.3" @ 173
STF 2465 (9, 10.4) // 1.2" @ 249 ... like a pair of headlights
STF 2356 (8.8, 9.2) // 1.0" @ 63
Bootes ... clouds moving through Lyra bumped me over to the other part of the sky
STT 288 (6.9, 7.6) // 0.96" @ 156
Cygnus ... clearing clouds gave me a window here
STT 410 (6.7, 6.8) // 0.9 @ 3
So that's 8 down and 4 more to go. It's supposed to be clear again over the weekend so hopefully I get a few more windows to work and see if I can't split a few more of these.
