  1. I think the shot is very good when you consider the size of the scope. What do you mean by 'blockier'?. The tracking may be drifting and that could give you stars that are not round. I get around this by using shorter subs. Mike
  2. Nice one - I must remember to keep a look out for these sorts of shots. Well done. Mike
  3. Simply and clearly explained - my kind of approach. Thank you for posting it. Mike
  4. For those who think flying saucers do not exist; here is the evidence - FGC 1953 (UGC 10043) in Serpens. No need to worry it is moving away from us! Mike
  5. NGC 5914B in Bootes is around the 1 billion lyr distance and is near to VV 1750. I could not find any other information on this galaxy. Mike
  6. This Nova was picked up on June 12, estimated at mag 6. See https://www.britastro.org/node/26011. Mike
  7. Martin that is a superb shot, no doubt due to the excellent sky conditions. The colour works well. Mike
  8. Hi Martin, You did well with the Pal 5 - so much better than my set up. Makes me think I should try again but you do have the advantage of it being higher in the sky. Envious of you being able to get the low down globs. Mike
  9. Congratulations on completing the tour - well worth it. Mike
  10. I have checked my M82 shots from the past - no sign of Hoag 1-3. However I notice below the number 9 of 20.9 the faint fuzz you have picked up is probably a galaxy at 2.6 Gyr distance.
  11. Colour makes such a difference. I have this PN on my list for the 15. As you know I just love a double star and great to clearly see the colour contrast in Bu 158. Mike
  12. Arp 72 in Serpens - NGC 5996/5994. Also known as VV016. I visited this Arp twice in 24 hours, trying to see just how much of the extensive faint arms I could pick up. As is often the case I get side tracked. Arp classified this pair as spiral galaxy with small high surface brightness companion on an arm. The two galaxies are separated by about 1 million lyrs and lie 157/156 million lyrs away. 5996 is classified SBc pec or SBc,WR,H11,Sbrst . The interaction between the two galaxies has certainly disrupted 5996, leading to much star formation (H11 regions) and intense star formation (Starburst). Spectral analysis shows the presence of Wolf Rayet stars (WR). My upper shot is a longer exposure to get hints of the extensive/faint material on the NGC 5994 side (the small companion) and also hints of the sweeping arm to the north (up) which then curls left and down. The lower shot has two distant galaxies marked - both a mere 3.8 Gyr away!!!! I have not checked out the various fuzz spots for the presence of galaxies. Mike
  13. I probably should go back to this one and run the camera for longer. I did actually run it for about 5 minutes and then deleted the poor subs (the unsteady ones). As usual, so much to see.. Mike
  14. Good point about the accuracies at that distance. Mike
  15. June 1st 2021 - there was me pottering about in Serpens and looking at my lists I saw this bright galaxy - NGC 5921 (mag 10). What a surprise when this ring galaxy appeared on the screen. Classified as SB(r)bc LINER (= bright nucleus). It lies 79 million lyrs away, has a strong bar and a slightly elliptical bulge. The two spiral arms have many H11 regions (I picked up a few of them). This inner ring galaxy was not even on my list of ring galaxies. Mike
  16. Serpens has just one SHK - number 360 and what a gem it is, well worth a visit. The scope was not tracking very well but Jocular managed to stack the subs well enough to get this view. As with most of the SHKs it is easy to pass them by. Many of the fuzz spots in the wider fov shot are mag 19 galaxies. 14 members make up SHK 360 with the brightest central galaxy coming in at mag 16.9 and down to mag 21 (rather pleased to pick this up). The complete group is not likely to be a true group as distance ranges from 1.378Gly to 1.440Gly. Using the NED data the reality is there are two (or more?) galaxy groups that we see in line of sight. Mike
  17. Pal 5 in Serpens. I visited this globular as recorded at the start of this thread. Here it is again but this time with the 15/ultrastar set up. Even with this large aperture and over 5 minutes of exposure it is still very faint. Mike
  18. PK69+3.1 (K3-46) in Cygnus is not an easy target and on my first attempt I failed to get it. Last night conditions were good enough to give it a go - success. It lies about 7,200 lyrs away and is thought to be about 20,000 years old. It has an hour glass shape with a bright equatorial ring. It is expanding much faster in the polar direction. It is easily missed in the concentrated star field - see my wide field image. North is up in both views. Mike
  19. I would not waste my time or money on it. It only has 4.5" aperture. Buy a 8" Quattro Newt, appropriate mount and camera and still have money in your pocket, see much more and in more detail... Mike
  20. Hi, wonderful shot and as you know I do enjoy the added information - makes it so much more worthwhile and informative. Interesting to note your use of the Baader filter - I have never thought to try that. Mike
  21. Hi Achim - back to using the black charcoal and hey presto it goes 3D. Have fun. Mike
  22. So much to see in the light summer skies. - many double stars of interest, globular clusters in Ophiuchus. Some of the best views of the Milky Way can be had in the summer months. We shall not have any true darkness now until early August. The sky will be darkest to the south so a good direction to look. I tend to go to bed early for a rest/sleep and then get up around 11.30 and enjoy a couple of hours observing. Moon sketching is fun on a warm summer evening for an hour or two after sunset. As has been said - astronomy is an all year activity. Mike
  23. Hi Achim, nice idea to look at this obscure dorsum. I have spotted it in the past but not made the effort to properly observe it. Re not using charcoal - always good to try out new approaches but my first reaction is the lack of charcoal makes the sketch look flat. It lacks the 3D effect that you normally capture so well. Have fun, Mike
  24. Hickson 69 found in Bootes is easy to miss because it lies in a wonderful galaxy field of obvious and distant faint galaxies. H 69 is a group of 4 galaxies with UGC 8842 (Sc -spiral) being the main galaxy. It is about 425 Gyr away. All four members lie at a similar distance. Actually all the obvious galaxies in this fov lie around the 400+ Gyr. Ignore the ASI 174 label (bug in the system) - I used the ultrastar. Mike
  25. Just ask when/if you are uncertain of procedures, techniques....always helpful on this forum. Mike
