bish Posted September 21 Share Posted September 21 A really bright comet. Need to keep our fingers crossed. Link to comment Share on other sites More sharing options...
Waddensky Posted September 21 Share Posted September 21 Yes, a comet to look forward to. Unfortunately quite low above the horizon for mid-northern latitudes when it's at its brightest. Link to comment Share on other sites More sharing options...
Nik271 Posted September 21 Share Posted September 21 It should look nice and bright from mid October in the early evening sky. The peak brightness will have passed but maybe it will still be spectacular🤞 Link to comment Share on other sites More sharing options...
JeremyS Posted September 21 Share Posted September 21 The article cited by Nick James has a balanced view of the prospects: https://britastro.org/section_news_item/comet-c-2023-a3-tsuchinshan-atlas-looking-good-for-october 5 Link to comment Share on other sites More sharing options...
Paul M Posted September 21 Share Posted September 21 Not the best geometry for easy observation during its period of best prospects but worth the effort of looking. The problem with comets isn't the likely diassapointment, it's the over optimism! Link to comment Share on other sites More sharing options...
Geoff Lister Posted September 22 Share Posted September 22 I ran Stellarium, with this comet centred, and stepped through date & time. I put a marker in my diary for October 13th, at 19:10, with about a 10 degree altitude separation from the horizon/setting Sun, at an azimuth of 255 degrees. Stellarium has it at magnitude +1, but this is likely to be an estimate, using old data. The background sky may be too bright for my Dwarf or Seestar to plate solve, but my 15x70 binoculars on my monopod should be fine. Clouds permitting!

Geoff It's going to be so low on the horizon I'm going to have to go to the coast or get to the top of a hill. Starry Night shows an estimated magnitude of +4.47 using the latest data files, but no idea how recent the data is for the comet itself. 1 Link to comment Share on other sites More sharing options...
Tony Acorn Posted September 23 Share Posted September 23 Some while back I gambled that this would be visible in our evening skies so I planned a week's trip to the Isle of Wight for late October and this may well give me a chance looking southwest to west over the sea. My Nikon Z6ii and one of: 14mm, 14-28mm, 24-70mm and 70-200mm lenses will sit on one tripod whilst my the 80mm ED f/6.25 will be on another. Of course I am already praying to the weather gods. So far, efforts to find sacrificial lambs aren't proving very successful. Tony 2 Link to comment Share on other sites More sharing options...
maw lod qan Posted September 24 Share Posted September 24 If it's only 10° I would definitely have to go to the beach. It would be worth it to get an image of a bright comet. Link to comment Share on other sites More sharing options...
michael.h.f.wilkinson Posted September 24 Share Posted September 24 Will be watching out for this one. It would be comet number 40 for me. Fingers crossed. Link to comment Share on other sites More sharing options...

PeterW Posted September 24 Share Posted September 24 Popped a note in the calendar to observe every evening from the second week of October… maybe a day or so earlier so I can work out where on the horizon from where I normally observe it might be.

mcrowle Posted September 24 Share Posted September 24 (edited) I may try a morning in the next few days, if the weather looks promising. Saturday morning looks best at the moment. With the comet only a few degrees above the horizon in bright twilight, I'll need to head to a beach 30-minutes walk away to have any hope. Regards, Mike.

Geoff Lister Posted September 26 Share Posted September 26 My last Seestar image of this comet was on the 24th of June. It will be nice to see my old friend back again - hopefully rejuvenated. Geoff 3 Link to comment Share on other sites More sharing options...

I thought I took another sometime, but didn't find it when I did the quick check. 2 Link to comment Share on other sites More sharing options...
mcrowle Posted September 28 Share Posted September 28 I made an attempt to see and image Tsuchinshan-ATLAS this morning from the nearby coast, but had no success. There was some cloud around, but the relevant direction, using the waning Moon for orientation, was often clear. Nothing was visible on the camera LCD or via binoculars. Regards, Mike. 2 1 Link to comment Share on other sites More sharing options...

Same here , I think the dawn was overwhelming the Comet. I think some people did get it, but it wasn't easy. 1 1 Link to comment Share on other sites More sharing options...
