  1. I’m having a problem with using a Starlight Xpress filter wheel with Starlight Live. I recently bought a new laptop and have installed Starlight Live on it. It works fine with my Lodestar X2 for mono imaging but when I connect the filter wheel it does not detect it. (Or more correctly it has only detected it once.) The filter wheel is detected OK on my older laptop. Also on the new laptop I can see and control the filter wheel with APT instead of Starlight Live (using the filter wheel’s ASCOM driver.) My new laptop only has USB 3.1 ports. The old one only has USB 2.0. So, I’m wondering if this could be part of the problem. If I connect a USB C to USB 2.0 adaptor and then connect the wheel this does not improve matters. The filter wheel makes all the right noises and goes for a circuit when I connect it to the laptop. When I look in Device Manager the wheel can be seen as USB input device under Human Interface Devices. I've tried with both SLL v3.3 and v3.4. Any ideas? Best regards Bill
  2. Martin That's strikingly beautiful. Very well described by Magda Streicher in the article that is your reference [4]. Not impossible for me so perhaps one night.
  3. Looking at background information about your targets I see that Stephen J O'Meara gave NGC 2301 the nickname 'Hagrid's Dragon'. Does a dragon class as a great bird? http://www.astronomy.com/observing/observing-podcasts/2014/02/m48-hagrids-dragon-and-ngc-2832 Best regards
  4. That's a good challenge you've set yourself. SHK 85 comes up using an internet linked object search in Cartes du Ciel but that probably does not add anything to Sky Map Pro and Sky Safari. You can get a list of them all from https://heasarc.gsfc.nasa.gov/db-perl/W3Browse/w3query.pl and look at individual ones clicking on for example 'o' to get DSS images. Don't know if this is any help. e.g. this for SHK 085-2 https://skyview.gsfc.nasa.gov/current/cgi/runquery.pl?VCOORD=118.9196,%2B54.7769&SURVEY=Digitized+Sky+Survey Best regards
  5. Great shots, Martin. 'scuse my ignorance - what are the N designations? e.g. N 122 for Berkeley 77 given in the inverted mono shots. I've feeling I should know but can't remember.
  6. Or another place to look to get a similar but slightly smaller distance is https://ned.ipac.caltech.edu/byname?objname=NGC 1262&hconst=67.8&omegam=0.308&omegav=0.692&wmap=4&corr_z=1 509.06 MPc 1660 Mly It's definitely a long way.
  7. Mike / Martin That's a mighty haul of galaxies. Mike - what are you using to identify the PGCs in your shot?
  8. Yes indeed a nice one. I see that Wikipedia says it's the most distant object of the New General Catalogue. So another good reason to have a look at it.
  9. Prompted by the interesting reports from alanjgreen (4 supernovae), Cosmic Geoff's comet report and recent reports from others I managed to have a look with my 200 mm f/5 Newtonian + 0.5ish focal reducer and Lodestar together with Starlight Live and Jocular. The only one of the four possible supernovae that was above the horizon was the one in NGC 4441. I was a bit surprised how bright it was. I think it must have brightened but did not find any data. It's close to the core and very obvious. The comet (C/2017 T2) was visible too and I managed a snap. Had a bit of look at a few other things including the Webb Deep Sky Society's Galaxy of the Month for January 2020, which is NGC 2563. https://www.webbdeepsky.com/galaxies/2020/ The finder chart is useful for identifying some of the other galaxies in the field. https://www.webbdeepsky.com/images/galaxies/ngc2563/ngc2563_finder.pdf While the sky was clear I could not resist a look at some of the old favourites in Orion. The Horsehead and Flame Nebulae for example. Observing and recording The Flame Nebula benefited from Jocular's scan and exclude subs. There were some intruding trails on some subs (dotted, so an aircraft, I assume). Next question. When is it going to be clear again? All the best
  10. A great set of shots, Mike. Well done Bill

    Arp 123

    A bit of a desperate one here. I managed to snap this a few days ago just before the clouds closed over completely. Arp 123 is the Webb Deep Sky Society's Galaxy of the Month for December 2019. See: https://www.webbdeepsky.com/galaxies/ https://www.webbdeepsky.com/images/galaxies/arp123/arp123_finder.pdf I was pleased to have snapped MCG-2-14-15 as well. Always, satisfying to see that visually it is described a challenge in a 15 inch telescope. It's wonderful what EEVA equipment (Lodestar X2) and software (Starlight Live + Jocular) can do with an 8 inch / 200 mm Newtonian. Arp 123 was only just poking over my neighbour's fence too. I'll have to have another look when the skies are better. Best regards
  12. Well, you've certainly captured it. An interesting object and the colour gives added interest. Keep 'em coming!
  13. A fine collection of galaxies you've got there.
