Hi there. after C/2015 V2 Johnson https://photos.app.goo.gl/yIbgsliYNY047pOl2 and P41/Tuttle-Giacobini-Kresak https://photos.app.goo.gl/FwBAZD4z0cE15dMn2 last year I though I try on C/2017 T1 Heinze. I was hoping for my first comet with a tail. I must say that I am using a Nikon D5100 with a Vivitar S1 3.5@210mm on a NexStar SLT Goto Mount. I am living in Berlin, close to the airport Schönefeld, so high light pollution (not to curse about the neighbors who seem to fear darkness so much that they plastered thier houses with LED lamps). So I used a rough alignment on Deneb, beause it was already below 0°C yesterday 18:00 local time. Then I slewed to Heinze with Stellariums help and got the right direction I guess (FOW is 6x4° with the said setup). I used then Astrotortilla to check and re-slew my (wacky) mount to exact the given position. Then I started to do 20s exposures at 800ISO which already gave me red skies and I though a good compromise of tracking and light. I was expecting at least a fuzzy spot but nothing. Rechecked the coordinates with calsky.org and today with theskylive.com It should have been there I guess. But I cant exclude some stupid errors from me. I used also DSS Live Stacker to get a better idea how it would turn out, and also after stacking I got nothing. Maybe it is one of the star-like pixels in center but how do I check? Stellarium does not show enough stars, I tried DS9 but this crashes so often on me. Maybe I can load some star chart/image and compare it with my astrometry.net solved FITS with embedded coordinates? Maybe I also could not get enough light, or the comet is to small for my apreture? May I was hoping too much after the tellings about the magnitude? Cheers, Carsten
Hi, after almost 2 months of clouds there was finally a clear night in sight. I made most of it, imaging until clouds rolled in about 4 in the morning. I shot these using two telescopes at Taurus Hill Observatory. Its fun to operate two at the same time, luckily its possible from indoors. Ill also attach here light curve of variable star V0416 UMa that I made during the same night with C14 and SBIG ST-8 on Paramount ME mark II. Other images are taken with 16" f/8 Meade SCT and SBIG STT8300M on Paramount ME mark I. Im expecially happy with Dembowska, I tried to get complete light curve twice in 2017 but clouds or fog always ruined my photometry. Milkyway was also beautiful as always, I spent some time outdoors just looking at it while telescopes clicked more subs. Worth every second in the cold, windy night!
