  1. I just got a planisphere this morning. Thanks a lot @Richard_B This is a really nice-to-have item for visual observation and not messing my dark adaption using the phone app.
  2. Thanks Richard, I don't necessarily need one, it's a nice-to-have sort of thing really. I think the stars move very slowly over decades but for the most part, the sky it's mostly the same as it was 20 years ago I think. For planets it's different story I guess. I also use a couple of apps that are quite handy, they mess with your dark adaption, however.
  3. This is my first upgrade for my 8" f6 Dob after quite a bit of research and insight from you guys. A rebranded Explore Scientific 82 24mm from Opticstar (first class dealers as John said, highly recommended).
  4. Hi Baz, It's good to hear from you. The click-lock systems is lovely yes. The one you point at is the extension bit only. I want to change the 2" focuser fitting/adapter as well (the M54 connection) I might get this one plus the extender you mention. https://www.firstlightoptics.com/adapters/astro-essentials-2-inch-compression-ring-adapter-for-sky-watcher-newtonians-and-72ed-refractor-m54.html Going fully click-lock makes the fitting plus the 37mm extension 10mm too long, I am not sure if I'll need those 10mm of in-travel focus.
  5. Sorry to revive this thread but I am about to do something very similar with the Baader Click-lock system. I have a SW Skyliner 200p, same focuser fitting and adapters. (11mm and 47mm respectively of optical length) That is an effective optical length of 58mm for any adapter. I am planning to change the fitting with the baader click-lock, the one below. https://www.firstlightoptics.com/adapters/baader-2-clicklock-m54-clamp.html That alone has a 30mm of optical length, I am guessing that is too short to the "stock" optical length. I'll be missing 27mm of back-travel in
  6. potentially another re-branded ES 2X 2" focal extender? @johninderby @KP82 @Stu1smartcookie even cheaper. https://www.altairastro.com/altair-lightwave-2x-2-inch-flat-field-apo-tele-extender-barlow-2833-p.asp
  7. I had been saving globular cluster for clearer nights. Last night was probably the clearest night I've had in the last month or so. I had never attempted one before. Literally last night was my first time ever with globular clusters. I drive my 8" Dob half for 30min to get to a Bortle 4 area, just for context. I am a total beginner too. I took my time. I started NW with the double clusters near Cassiopeia. I love that one. Moved W to Auriga, M36, M37, M38, very beginners friendly and a lovely sight. Spent a good time in M35 in Gemini (although the waxing moon was too close).
  8. I can tell you this regarding your comment. I contacted several companies, some in Europe too (they seem to have better stock), and the guys from Opticstar were the most responsive ones by a long shot. Just ordered the XL 82 24mm with them.
  9. Thanks John, just wanted to make sure, it just seemed too good to be true. ES are already good value EP in terms of performance per dollar, and on top of that you can get a cheaper re-branded version with the same performance. Plus this, price is pre-rise. Made it a no-brainer for me considering the current circumstances with price and availability.
  10. I reckoned I better digress here instead of creating a new whole discussion. Is it just literally an Explore Scientific re-brand? or is there a catch? Browsing around I noticed that Opticstar also has a re-branded ES82 lineup that is 40quid cheaper than the actual Explore Scientific one, and they actually have stock. http://www.opticstar.com/Run/Astronomy/Astro-Accessories-Telescopes-Opticstar.asp?p=0_10_5_1_8_322 Is it just literally a name change? I reckon if the eyepiece is made in the same factory in China, there will be zero optical perfomance difference and the is no
  11. @Louis D, Do you think the same can be achieved with an ES82 24mm? the specs say it has 17.5mm of eye relief, in practice Don mentioned it has more like 14mm of effective eye relief. Haven't read any comments about folding the eyecups in the ES82 eyepieces.
  12. Thanks Steve. Very useful information as usual. That chart from televue is handy. Another reason for me to maybe stay around the 4mm exit pupil or maybe observe with my right eye which doesn't have any cylinder correction (I tend to observe with me left eye for some reason, the one with -0.5 Cyl) I've read good things about that Omegon (and re-brands), I'll keep it in mind. The APM Ultra Flat Field 30mm have been reported to be eyeglasses-friendly when the eyecup is folded down. Still not anywhere near the 22mm of eye relief they state in the specs.
  13. Where did you buy from @Deadlake? Astrograph?
