  1. The sketch captures the ruggedness of the area - a good detailed sketch. Mike (My observing/sketching days have come to an end.)
  2. Excellent sketch which captures this object. Mike
  3. Hi Richard, Enjoyed your post - close to what I would see with a 20"Dob. I too went from visual to non-colour EEVA for the the 'more natural' view and stayed with black/white for my years of using EEVA to 'observe'. Colour does have value for PNs, studying star clusters and for picking up hydrogen alpha regions in galaxies. Enjoy the EEVA journey. Mike
  4. Hi Nick, If you look through the EEVA section for posts by William Scutcher and Martin Meridith you will find many examples of what can be achieved with a 8" Newt. Operating at f6 will be fine but Bill (William) used a focal reducer and if I remember correctly Martin was using a Quattro at around the f4 region. Both used lodestar quide camers. When I was active at the same time as Bill and Martin there results frequently came close to my 15"/ultrastar set up. Use what ever gear you have and enjoy yourself. Cheers, Mike
  5. Go for DSO - so many adventures to be had. Planetary is limited for opportunities.
  6. Excellent collection and such good results. I have just checked against my archive of Arps and none of mine add anymore details, despite using the 15. Mike
  7. Hi Pete, I used a C9.25 for awhile using the EEVA approach. You probably have about 50,000 targets within reach. Messiers, Herschel 400, Caldwell, the brighter (and more interesting) NGC - around 600 of them, the Arps, the Hicksons, then the VVs, SHKs, WBLs, PCGs, Ring Galaxies.......and so it goes on. If you look in the EEVA Reports section you will find threads assigned to the various lists. Enjoy the journey, Mike
  8. Well done, good to take a look at the Arps and to ponder what is going on with the galaxies. It does seem to be uncertain as what is causing the disturbance. Enjoy your EEVA journey - I have sold my gear - age catching up on me........time to move on. Mike
  9. Always worth a go at the low down objects. The central white dwarf star is obviously white in your shot. Mike
  10. Lovely to see this Arp again. By reducing the brightness I picked up hint of the arms around the core. Also my shot clearly shows PGC 10169 and always nice to pick up a quasar. Mike
  11. It also has a very active nucleus. A very fine member of our local galaxy group. Mike
  12. Well done. You will not live long enough to see all the targets within reach of the scope (even if you live to 100yrs!!!). Mike
  13. Hi Martin, I am glad you have drawn my attention to '6' in 365 - looking at NED, this galaxy would appear to be a spiral tilted towards us and hence I seem to have got a hint of the spiral nature. NED gave no details for the galaxies in 365, so no idea of distance or magnitudes. '8' in 142 - NED gives no clues. Mike
  14. I came across VV 968 in Pisces. It is designated as NN = 3+ galaxies but disrupted. The two close galaxies in professional images hint at the galaxies disrupting each other. The third member is off to the left. They all have very similar redshift values. Just above the middle galaxy is a small fuzz patch - this galaxy is much further out. The indicated quasar is 3+ billion lyrs away but I doubt it is mag 21: maybe mag 19/20 Mike
  15. and here is another SHK in Pisces - SHK 365 - a linear grouping. Mike
  16. It has been a while since we had a SHK. SHK 142 in Pisces. This group of 10 galaxies is a good example of a spread out SHK galaxy group. As is often the case when the first sub comes in, I wonder if I have located the group - see the first sub below. Initially I thought it was in the centre towards the top of the shot As the subs stack, all is revealed. and here is the close up. Mike
  17. A PCG in Pisces. They always give me a thrill to find them and to know they lie a long way out. Certainly, it would be a nightmare to locate without GOTO; they are so easy to miss. Look for a small group of fuzz spots. Other faint galaxies can be seen in this shot - in the region of mag 18/19. A close up shot. Mike
  18. Hi Bill/Martin, At last, I have got around to taking a look at this wonderful galaxy. Not the most transparent conditions last night. However, a little more detail picked up, but not sufficient to make anyone rush out and get a scope bigger than the 8" scopes that you use. (Although as usual it only took 5 mins of subs). Mike
  19. Agree with Martin/Geoff. As has often been demonstrated in the EEVA reports, 8" scopes often rival my 15" setup for detail although most time my set up probably has the slight edge. From my visual days here in GB the generally poor seeing meant only on the rare occasions could I use the 15 to its full effect but then when I could Jupiter would be awesome. In GB scopes in the 8-10 " range do best in our poor seeing. The obvious plus of the 15 is the speed at which I can get a shot because of its large light gathering. Mike
  20. Three for the price of one - Arps 48, 119 and 88 in one shot. Located in Pisces. Arp 48 is bottom left. Arp 119 is the obvious central pair and Arp 88 is the very faint pair to the right. Arp 48 is classed as spiral with low surface brightness Arp 119 is and elliptical disturbing a spiral companion on its arm. Arp 88 is a spiral with a high surface brightness companion on its arm. Mike
  21. Supernova 2022wsp is a type 2 and can be found in NGC 7448, which resides in Pegasus, NGC 7448 is also catalogued as Arp 13 (see Arp thread for more details). First shot is from 2 years ago - no SN. This shot is my recent one - look just below the core for the SN This zoomed in shot shows much more of the galaxy detail and the SN close to the core. Mike
  22. Asteroid Bella, around the mag 9 mark and part of the main asteroid belt. Whilst messing about finding Arps I thought I would make the effort to see how far Bella might move in an hour or so. On the left is my first shot and on the right at just over an hour is the same shot. I will leave you to spot Bella. A fun exercise. Mike
  23. Thanks Martin, I have tried what you suggest but no red squares! Dave thanks for adding in the extra info. I have just made the effort to look at VizieR data - https://vizier.cds.unistra.fr/viz-bin/VizieR?-source=J/AJ/118/2014 These tables would suggest the three galaxies I listed? All good fun Mike
  24. WBL 674 can be found in Pegasus. I enjoy these groups because there is often a variety of galaxies in the group, they have bright (ish) members and frequently other objects of interest lurk in the view. For you guys with a wider fov, these are well worth tracking down. There is much to enjoy in the view below. Three galaxies make up WBL 674 but which three? WBL 674 = IC 5145, IC 5144 and ? (probably CGCG 427-039). Looking at the redshift data IC 5145 lies about 332 million lyrs away but the rest of the galaxies in view are around the 400 million lyr distance. IC 5144 is at 411 million lyrs and is a barred spiral. Just to the right of CGCG 427-039 is a piece of galactic fuzz - no ID given by NED. The quasar - top right, mag 20 (don't believe it - my set up can go that deep but it is way too bright for that faint magnitude) and its redshift value puts it way out at approx 11 billion lyrs!! Close up of IC 5145 showing its spiral nature. Mike
  25. Hi Peter, Excellent; you are up and running with EEVA. I am sure you will find it useful as your target fainter DSOs to use 10-15 sec subs and maybe do as many as 30 stacks. You are quite right that we loose touch with the universe when we stop doing visual. I will always check where an object is in a constellation and just sit outside enjoying the stars whilst my 30 subs are coming in. I also tend to finish a session by staring at the night sky after I have packed the gear away. Don't forget that within the 'Reports' section we have quite a few dedicated threads to the various DSO lists so if you do find yourself doing an object where there is a thread, then just add it in. See below for the current list. Mike List of SGL threads.docx
