Observing Report 1st-2nd April 2013 (Another pop at Pan-STARRS)

Posted by on April 4th 2013 in Astrostuff, My vids, Observing Reports, Pics

Same Comet, same conditions, same tree, same faff, different night:

Comet Pan-STARRS (C/2011 L4).
Subs: 25 light @ 30s, darks, bias frames, ISO1600.
1000D on the 6" R-C, unguided
.

The main difference is that this time there's a time-lapse movie. I created it from 100 frames, each representing 30 seconds of exposure and 5 seconds of "gap", so that's nigh on an hour crammed into this 10-second clip:

Observing Report 29th March 2013 (A quick and dirty Pan-STARRS)

Managed a few binocular glimpses of Comet Pan-STARRS (C/2011 L4) between the clouds last night, then I got to wondering if it was sufficiently north and high for me to be able to train the obsy-based telescope on it.

After a bit of a faff moving the roof a good foot further along than usual, and then removing the screen that keeps out the glare from the retirement-home up the road, the only obstruction was the neighbour's Japanese Maple. I couldn't cut it down and it wouldn't bend out of the way so I decided to just pretend it wasn't there and take the shots through it anyway. After all, if this hobby was easy, everybody would be doing it!

Despite the tree, the light-pollution haze near the horizon, the comet's low altitude, the glare from several 500W halogen burglar-helpers and a mere 15-minute window of opportunity when the comet was visible between houses, the result's not so bad after all:

Observing Report 13th March 2013 (Comet Pan-STARRS (C/2011 L4))

I managed to get away for a couple of hours around sundown last night, it was the first clear(ish) evening for a while and the first chance we'd had to have a look at Comet Pan-STARRS (C/2011 L4). Finding it was an interesting experience - too soon after sunset and the skies were still too light, and later when the skies had darkened the comet was so close to the horizon that it stood a chance of being lost in the murk of haze, cloud and light-pollution.

Persistence was the key. Eventually the bank of low snow-cloud moved away and revealed the target. It's not visible with the naked-eye yet during these conditions but it's an impressive sight through 10x50 binoculars. The 70-300 lens on the D50 picked it out quite easily.

Here's one of many pics from the evening, I'll post a few more later:
