  1. Hi all This is more of a cry for help than a showcase but I seem to have produced a situation where a single sub is giving me a better result than a DSS stacked image! The long and short of it is last night (16/01/2015) was the first clear night for ages so I spent some time outside trying to get as much data as possible in varying formats (ISO800, 1600 and 800 with Powermate). The examples below are ones taken at native FL at ISO1600 with a non-modded Canon 1100D with Astronomik LP filter through the WO GTF81. Subs are 120 seconds, 24 of them (a few more lost to star trails probably caused by the wind). At first I saw the subs coming through looking reasonably good, albeit bluish thanks to the LP filter. I could see a bit of a tail and was encouraged that I might get a good result after stacking with DSS. An example of one of the subs (in JPG format, the CR2's are even better but of course I can't upload them here to view) is below: After all subs were taken I took another 25 bias. Started to take darks but then had snow so had to bring everything in - I used darks from the library so not ideal. Flats also from the library. Stacked them in DSS using the 'stars and comets' option (option 3 for those who know DSS) but the result that came out the other side has sadly given me very little. I've stretched it beyond reason in PS CS5 and there simply isn't much there (see PNG output below): If you fancy a stab at the data feel free to grab the 16-bit TIF here or the 32-bit TIF here. So the question is, any ideas? What am I doing wrong or is there anything else I can get out of this? Or is the equipment simply not good enough to get the detail, especially with the LP filter? As always I value everyone's opinion so don't hesitate to throw anything at me! Cheers all Will
  2. Comet Lovejoy...also known as C/2014 Q2. London, 6th January 2015
  3. The Binocular Sky Newsletter for December 2013 is now available. Things have been a tad hectic recently at "BinoSky Central" , so this is a tad shorter than usual but, I hope, will still be useful. What I try to pass off as "normal service" will be resumed as soon as possible... In addition to the usual selection of good DSOs and Solar System objects to observe, in this month's issue we also have: * Comet Lovejoy * Many lunar occultations * A selection of variable stars To grab your (free!) copy, go to http://binocularsky.com/ and click on the Newsletter tab. I hope you find it useful.

  5. As well as being naked eye visible tonight, comet Lovejoy is absolutely stunning in my 10 x 50s. The nucleas is very bright a fuzzy with a stellar-like core and the tail can also be seen, though ony faintly, streaming off. It's a more rewarding sight in my bins that in my 200p with a 32 m EP. I'm lucky that it's clear for the moment and I'm just in for a tea before nipping out again. The telescope is busy imaging but I'll be gauping at the comet with my bins.
  6. Equipment: Canon 7D2, ISO1600, Sigma 150mm f/2.8 macro at f/2.8, Astronomik CLS CCD filter, 161 x 30s exposures. Took more but rejected a load due to cloud. Tracking background stars unguided with lousy polar alignment. Processing: Starting with PixInsight, flats, star align, comet align, stack, stretch, DBE, curves, photoshop. Above is only a comet aligned stack. I've tried to optimise viewing for the tail in this image.
  7. a play last night with Comet Lovejoy with a Canon 5D3 and 70-200mm f/2.8 lens while I was there I couldn't resist a pop at M45, the Seven Sisters

    Comet Lovejoy on 8th Feb 2015. Processed using Hubl's method to freeze the comet vs static starfield.
  9. So my take on Lovejoy Skywatcher 250 with a Modded Cannon 450d This is 5 mins of 20 sec exposures, I added darks and flats You can just make out the beginnings of a tail, next time I need longer exposures, however its my first comet so cant complain (probably my last given the recent weather) Thanks for looking Regards John B
  10. Here it is again, my space video of Comet Lovejoy, with additional processing to bring out the color, and a new original music soundtrack that I composed for the comet. I used the Orion Starshoot Deep Space Video Camera II to capture the image through an Orion StarMax 127 Mak-Cass. Enjoy! Reggie
  11. When I got home it was clear and, after checking some on-line charts, I went looking for comet Lovejoy. Sure enough I found it fairly easily by tracking to the right from Hercules. The head appeared larger than M13 and by concentrating it was possible to make out a slightly brighter core. The tail was also apparent and there were occasional glimpses of filaments. Well worth a look, though it's probably best viewed just after dark when it's higher above the murk over the horizon.

  15. 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.

    Widefield of Comet Lovejoy from 24 January 2015. Taken with a Canon EOS 700d and very cheap 50mm f1.8 lens. First time I've used this lens for shooting the sky and f1.8 was probably too much aperture as it seemed to make focus difficult. I'll try stopping down next time
