  1. Comet Lovejoy...also known as C/2014 Q2. London, 6th January 2015
  2. COMET C/2014 E2 JACQUES Meets the OPEN CLUSTER NGC 609 23 / 08 / 2014This is my first attempt at a Comet. After having various issues with stacking and a rogue stretched star as a result of a stacking error. I can finally feel proud after relentless hours spent at stacking and re-stacking this image. I feel proud I managed to process this Comet as well as it looks. I think there is a hint of a tail at the 3 O'clock position but who knows... The bonus is the comet is above an Open Cluster NGC 609 which adds more interest. Conditions were good and if I had set-up the Mount better I may have managed longer subs. There is a hint of star trails due to wind and tracking issues.16 x 30 secs Light Frames30 x 30 secs Dark FramesISO 800Skywatcher 200P 8" 1000mm ReflectorEQ5Canon 1100D ModdedBaader MKIII MPCC + Hutech IDAS LPS-D1 FilterHI-RES IMAGE:
  3. A composite image of Comet C/2015 V2 (Johnson) taken in the early hours of April 9th as it travelled between the constellations Hercules and Draco - processed twice in order to show the comet on a background of sharp stars (for purely aesthetic reasons). Because it appears as such a slow moving comet and is more distant than Comet 41P/Tuttle-Giacobini-Kresak, it was possible to take much longer exposures which is something of a luxury. 48 minutes and 45 seconds total integration time 39 x 75 second exposures at 400 ISO 40 x dark frames 31 x flat frames 21 x bias/offset frames (subtracted from flat frames only) Captured with APT Guided with PHD2 Processed in Nebulosity and Photoshop Equipment: Sky-Watcher Explorer-150PDS Skywatcher EQ5 Mount Orion 50mm Mini Guide Scope ZWO ASI120 MC imaging and guiding camera Canon 700D DSLR
  4. Now that ISON has crossed the orbit of Mars, it is time we start contemplating on possible techniques to photograph it. Personally I have a Sky-watcher 200PDS on the HEQ5-PRO goto mount, and my trusty Canon 550D. I have never attempted to photograph a comet before, so would highly appreciate any tip and advice from anyone in these forums.
  5. Just a reminder for you Shropshire/West Midlands folks, I'm arranging a low-key weekend of Perseid watching and general astronomy antics in Shropshire. Six quid a night, dark sky, friendly campsite. The details and some pictures are on my blog in the sig. Everyone welcome!
  6. First of all, HAPPY NEW YEAR all at SGL! Wishing you all a very enjoyable, prosperous and cloud free year. What are people's thoughts on the year ahead astronomically? I must admit I'm quite excited for the months ahead. There's quite a lot going on up there :-) 3 bright(ish) comets, two of these comets will be in the same constellation in April! All three should easily reach binocular viewing brightness. Then in August there's 'The Big One' if you live in America or are planning on visiting. Even though I wont witness it, I'm still intrigued as to how this will compare to the 1999 eclipse and just what kind of media frenzie the world will get in to on this one. Any other events people are looking forward to this year?
  7. A short time-lapse of the comet C/2014 Q2 travelling through a patch of London sky on 10th January 2014. The five second clip shows just under an hour of real time movement. - 82 x 20 second exposures at 3200 ISO (one shot every 40 seconds). Playback is at 15 frames per second. Sorry about the gif quality, I don't know if it's possible to show higher quality video here
  8. I got up at 4 this morning to do some comet hunting. The sky was clear overhead, but haze was making visibility poorer towards the horizon. Occasional threatening clouds passed, so I did not dare set up the scope. I got out the 15x70 bins, checked the finder charts for the comets, and headed out. Lovejoy was best placed by far, I aimed the bins above Leo's head and WHAM, there was the comet. A very bright core, large coma, and in averted vision a hint of tail. Very pleasing. I checked out the transparency of the sky by looking at M101, and could barely make it out, so conditions were not that good. M81 and M82 were nice, but I have seen them look better as well. I tried getting a look at C/2012 X1 (LINEAR) which has undergone a large outburst recently, and found that it was still too low. ISON was also hidden. I went back to bed for a short nap, and got up again at 5:40. Because Virgo was largely hidden by trees, I walked over to the football fields behind my house (and said trees), and managed to find a faint blob in averted vision close to Arcturus. It was very hard, due to the haze, but I repeatedly found (at least four times) and its location fitted the finder chart so comet number two found. ISON was playing hide and seek in some low haze/fog, so I went back home. I couldn't resist giving ISON one more try, this time from a first-floor window, and lo and behold, I spotted a "star" at a 2-3 degrees left and below Porrima, which showed a bit of fuzziness in averted vision. I went away from the object and found it again a couple of times, and it persistently showed a bit of fuzziness which brighter stars around it did not show, so it couldn't be a case of glare. The position also fits with the charts, so comet number three bagged. As the sky was already brightening a bit, I was not surprised that I could see no tail. So this is clearly my best comet chasing session to date, as I raised my (fairly meagre) tally of comets from 6 to 9 in one night. Obviously I felt very pleased, but duty called, as the alarm clocks went off at 6:30, and I had to make breakfast, chase up the kids, make lunch boxes, etc.
