  1. It is unfortunate that it falls the weekend before IAS (and the weekend after Kelling star aprty) two of the bigger events in the UK astro calendar.
  2. I know many people are aware of the Webb Society but I just thought I would put together a little note. First formed in 1967 the Webb Society was named after Thomas William Webb, author of Celestial objects for Common telescopes and over a fairly short period produced 7 handbooks covering various aspects of deep sky observing, all by volunteers. Although these are no longer in print they can often be found cheaply second hand and are still a valuable resource for deep sky observers. The society now has memebrs all over the world and publishes a regular deep sky magazine. It also has a website where there is information on the other publicatiosn we do as well as a double star of the month and a galaxy of the month at www.webbdeepsky.com. The society also hosts an annual meeting in Cambridge (UK) at the IOA and entrance is open to all, details on the web site. The society does tend to have a stand at most major star aprties as well as at the main trade shows (with the exception of AstroFest as that is too expensive to go to) so pop aroiund and say hello. We do also have a Facebook presence. Anybody with an interest in deep sky observing is open to join. Owen Brazell (Webb President)
  3. diffficult to judge numbers as the venue was very much smaller so seemed more crowded. Certainly after three on both days there were very few people there and Friday I don't think was so well attended, perhaps because of the weather and roads. Owen
  4. What events are you looking for? The dates for Astrofest and PAS are already posted as are the Kelling Star party events. Owen
  5. The Delos also have less glass to that may add in for the extar sharpness. I think the choice may depend on what your interests are and whether you have an undriven scope. Owen
  6. Your understanding is correct. a filter will not help for anything composed primarily of stars, such as galaxies and star clusters. Nor will they help much with reflection nebulae. Howevre if your targets are emission nebulae then a UHC type filter will help a lot from almost any skies. An OIII filter will help if you are primarily interested in planetary nebulae but would be the second filter to buy after a UHC type filter. Owen
  7. I think there may be small discounts but margins in the astronomy business are not great so don't expect huge ones. I would also think with the collpase of the £ anything coming from the US is likely to be more expensive the longer you leave it. I would also not expect many people to carry a Feathertouch focuser in stock. These are more likely to be special order. Owen
  8. The FAS (Federation of Astronomical Socities) is holding its annual meeting and AGM on Saturday 14th September at the IOA in Cambridge. There is a full lineup of speakers and more information is at http://fedastro.org.uk/fas/convention/convention-2019/ Owen
  9. assuming it updates from the MPC then there is an issue as the MPC data have not been updated since early June due to system and resource issues. with no timescale for this to be fixed. Owen
  10. As Steve also says he was not able to see it with a 17.5" it may depend on what size telescope you are using as to whether youc an claim to have seen it. I would also post on the CN forums as they are more likely to have large telescope users active in that kind of time frame. Owen
  11. The TeleVue OIII and H-Beta filters are pretty much identical to the Astronomil versions. The main improved one is the TeleVue Bandmate 2 UHC type filter which is really nice so I would not waste money trying to get a TeleVue OIII and compare to the Astronomik OIII as they are the same. Lumicon have undergone several buyouts since the orginal filters by Jack Marling. The current owner is Farpoint. Owen
  12. I don't believe there are any UK dealers that carry Lumicon stuff. There are some European dealers but their prices are very high and you would not be sure whether you where getting a Gen 3 filter or older stock. I suspect that unless you were very experienced with filters you would not see much diffrence and the Astronomik is a fine filter. Owen
  13. Good to see my old scope again after languishing for so long in Callum's shed. I replaced it with a 20" Obsession. Anyway some titbits the collimating design was Keith's at Dark Star and ES adapted it for their telescopes. Keith took the mirro set I had form a solid tube dobsonian and designed a new mount for it. I believe he made a few more telesocpes of that design but probably not many. The mirror is mounted on bubble pack but I believe Callum replaced the old bubble pack otherise it could be due to air leaking out. I think you will enjoy the brighter Abell galaxy clusters with that when it gets really dark. I don't think I ever used it with anything but Naglers so it will be in teresting to see what the modern designs will do. Your first view of M42 through it will blow your socks off. Owen
  14. Think I may wait a few more days before I upgrade in case there any more hidden bugs, and anyway it does not work under water which seems to be the case here for the next week Owen
