  1. Also try this Mike http://faintfuzzies.com/Files/RingGalaxies v4.pdf Owen
  2. If you have not already found it this is a good guide http://www.faintfuzzies.com/Files/AbellGalaxyClusters v1.pdf
  3. I suspect with the star party cancelled the lights from toilet blocks etc. will not be blocked out and you will be hit by uncontrolled lighting from normal campers. We have had this issue when people stay outisde the normal dates and it can get fractious.
  4. Unfortunately with the goverment options on opening campsites Kelling April star party for 2021 has been canceleld. You should hear from Kelling if you had booked about your options. This pretty much closes out the Spring Star party season, at least in observing terms for the UK I think. We can only hope for better in the Autumn.
  5. I spoke with Mike about these. NeVe6 is an HII region not a PN. J900 may not be well known in some circles but it has been well known amongst visual PN observers for a long time. It even made the Webb Soc Deep SKy Observers Handbook Vol 2 in 1978, along with J320 in Orion. It seems a shame that so much literature is ignored just because it is not on the internet now. People need to look back at older references..
  6. no point in trying with an OIII filter Martin as there is practically no OIII emission. The only filter that might help would be an H-ALpha one. Owen
  7. Mike not sure if you saw this, or indeed if it is the source for your information http://www.deepskyforum.com/attachment.php?attachmentid=3495&d=1556044862 It is Jimi Lowrey's list. Owen
  8. Hi Martin there was this transform V := G + 0.01760 + 0.006860 * (BPg−RPg) + 0.1732 * (BPg−RPg)^2 to get from GAIA G to approx V for GAIA DR2. I don't know if it still applies to GAIA EDR3. However obvioulsy magnitude estimates that faint are going to have realtively large error bars and I spspect that ga;laxy magnitude estimates at that level should be treated as aprriximate only. Owen
  9. Martin I have the physical Neckel and Vehrenberg Atlas and it is a 3 ring 3 folder printing. It was also scanned and digitised and sold as a DVD. I know I have a copy in the Webb sales boxes but I would need to check the original source. to see if it is still available there. The orginal source was http://www.stellarum.de/ Owen
  10. Well since the RAS has been doing this since its beginning I am not sure why the AAS is trying to extend its tentackles over here. The BAA has also been working closely with professionals for the majority of its existence.
  11. The accomadation at AstroAdventures is fairly basic but cozy. They have some telescopes for guest use including a 50cm dobsonian and an imaging setup. There is alos Eddington Lodge neraby whihc I think has a much more glamping style of lodge. They also have quite large telescopes to use but I have not been there.
  12. I am not sure if people have seen this Oculum reader survey 2020 (mailchi.mp) but the German publisher Oculum (I have no connection with them) are looking for input as to a couple of English language translations that they wae thinking of doing.
  13. I would look at the AstroAdventures site in Devon. If it is clear then it is awsome skies https://www.astroadventures.co.uk/ Probably more chance of clear skies than Keilder
  14. I think there maybe an issue with what all these "dark sky parks" are for. This maybe due to an issue with the way the IDA certifies them as it only inlcudes vertical SQM measurments, and almost no astronomer works at the zenith. What would be more useful is measurements taken at say 50 degrees. I think the defintion now is for people coming from brightly lit cities to see something rather than true dark skies. I doubt anywhere in England would have a true dark sky as the light pollution from cities reaches so far. As such it seems more of a game to set these things up rather than be useful fo
  15. If you subscribe to ATT then you can get PDF downloads of it. There are usually quite large in the 100Mb range though.
