  1. Thanks RL and Louis D for that information. We better go back to the original question for Blinky on 100 degree EPs.
  2. Thanks RL I like ES eyepieces and I must admit I really fancy trying the 17mm ES92.
  3. Rob I think if you asked that question in the 1960s then Charles Frank 4" or 6" scopes would be high on the list with regard to the UK only. I certainly remember the 4" scope being available via general home mail order catalogues. Then you had Fullerscopes or 60mm fracs like Prinz and Tasco. I certainly had a Japanese 60mm frac followed by a 6" Charles Frank Reflector on an EQ mount. I think your list is pretty good especially the Celestron C8 which had huge sales especially in the United States. The Meade ETX range 90 and 125 must have sold a great deal as well although I decided to buy the Celestron Nexstar 5 which cost well over a £1000 in 1999 and the mount was extra.
  4. I have a 12" f/5 Dob and currently use a 20mm Myriad, 13mm Ethos and a 9mm Myriad. I also have a number of ES82 EPs. The Myriad EPs are very good and I previously owned the 21mm and 8mm Ethos and there is not a huge difference IMHO. I think your best choice would be the 20mm Myriad and depending on funds I think a 14mm ES82 would be your next purchase. I did buy a 9mm Myriad after the purchase of the 20mm but this was because I already had a 11mm and 14mm ES82.
  5. Iain thanks for the 'heads up'. Nice image and video. As a result of your post I just grabbed the PST because the Sun has just come out. Able to see the new sunspot AR2637 and a nice Prom nearby.
  6. Thanks Gerry that is a very useful report. I guess you will buying 130P and a NPB for yourself
  7. Yes I fitted a standard shoe and simply drilled the metal tube. To get the correct position I used double sided tape and then drilled through the shoe and tube at the same time. The Red Dot Finder is similar to this one - However, I have used a 9x50 correct image finder and I am able to fit both the RDF and Finderscope together using one of these - It does make it heavy so I prefer just the RDF
  8. Thanks for that information Gerry. I have been using my 24mm ES68 and a TeleVue 8-24 zoom. For higher mags I found the 4.7mm and 6.7mm ES82 quite useful. My 100 degree EPs are just too large. I have also made a shroud out of neoprene because I was getting flare into the focuser. I also blacked the sides of the secondary to improve contrast. I don't expect to use this scope a great deal but it will useful to take away on holidays and the quick grab and go at home.
  9. The other 3 members in the photo were a local 'Pop' group and as well as sending me the photo they enclosed their CD called 'Winter Moon'.
  10. Yesterday someone sent me a photo of an observing session of the solar eclipse in 1968. I don't think I have ever seen this photo before. The scope was my 60mm Refractor and we view the eclipse through a Swift Herschel Wedge. The house was my Parents and the building behind the group was my wooden observatory. I am second from the left - a young 20 year old.
  11. No they are from WDS - I bought the 25mm length.
  12. I have used many scopes over the years and wanted a nice lightweight Reflector which I could use on my canal boat plus holidays abroad. I bought the base of the Heritage Flextube over a year ago from Astroboot and used it with the Altair 72mm Lightwave Frac that I owned at the time. Recently a Heritage 130P OTA became available on Astro,Buy and Sell and I was able to collect it to make sure it was okay. I have now added secondary knobs plus I attached a finderscope bracket. This Heritage OTA clearly sits nicely on the Dob base but I also had a Celestron AstroMaster Tripod which I bought from a FLO clearance sale mainly for my PST which gives me additional height. This is now my Grab and Go scope and I have already had some good views of the Moon plus some of the popular DSOs IMG_2273.xmp IMG_2274.xmp IMG_2275.xmp
  13. Marios a very nice sketch of one of my favourite asterisms. In my Helios 15x70 Apollo Binos I can cover the whole asterism - great sight.
  14. I would be quite happy to obtain a licence from the Police to be able to officially use a laser for a public star party. I use a laser to show Constellations and various DSOs at public events but I am always mindful if I can see aircraft .
  15. A laser collimator will not sort out the secondary you really need a site tube for that. Over the years I have found that the Cheshire gives me the most accurate collimation. I did have a Hutech which was convenient but in the end I returned to a site cap and a quality cheshire.
