  1. Yes - I think they were called shorties - it was the version with the camera threads on the end. As a 2x barlow, it was so bad that I cut it up when I needed parts to make adaptor bits & bobs, and was left with the removable end piece. The revelation 2x barlow has never let me down. My efforts above were in daylight focusing on distant trees. I had the binoviewer first light tonight on the crescent moon. And wow, it was worth the effort. With the supplied 1.85x barlow I could get focus, but there was a fringe halo of rainbow colours trying to come through on the edge of the moon = the set-up was difficult to focus, and never really sharp enough. Time to roll out the Revelation 3-element 2x Barlow. This gave a sharp focus, no edge colours, no shimmer from the atmosphere, and a massive magnification. It had the wow factor, so job done. When I tried the barlow and 16mm Maxvision 68-degree without the bino's - I got lots of shimmer. My guess is that the brain will cancel out the wobble due to atmospheric conditions when using the bino's. Ali express have 0.5 focal reducers for £4.69p with the sellers discount, so it would be rude not to buy one. It should be here in 4-weeks time.
  2. A quick update on the Binoviewer. They arrived with the expected 20% import duty, well packaged in a cardboard box - no bag or aluminium case was advertised, so all good so far. The cost with the included 1.85x and 3x end piece barlows = £67.90p plus £21.34p import duty = £89.24p, Two 23mm cheap eyepieces (at £5.78p each) bring the total up to a very reasonable £101 The Skywatcher 200p dob reaches focus with the 1.85 barlow only. The 76mm x 700 newtonian needs the 1.85x and a skywatcher 2x barlow endpiece to extend the focal length. Magnification options are going to be more restrictive than I thought. Advice for gaining focus without a massive barlow magnification would be appreciated. I had hoped to have nice wide 23mm views. But I am stuck with a single magnification for each scope - 100x on the 200p / and over 100x on the cheap 3-inch Newt. Weirdly, the dob focus appears to be: too short with no barlow / just right with the 1.85x / too long with the 3x barlow Good points They are very comfortable and relaxing to use. They are good quality kit, similar to the BST / OVL version. With lots of independent focus on each eyepiece holder - about 12mm adjustment. So you can lock the scope focus and use the 2x eyepiece adjusters to fine tune if required. Bad points Needs the additional 1.85x Barlow for most Newtonian type scopes to reach focus. They add weight - I need to tighten up the focus tube tensioner screw to stop it slipping down. You may need 2x good quality eyepieces to get the best out of the binos = double the cost
  3. Ali-Express should be able to deliver to Oz if you want a set of cheap binoveiwers to get you started. There is a sale on at the moment, so I ordered a set which are very similar, or the same as the BST Binoviewer. $130 Australian dollars, with a further money off voucher available from the seller if you click the right button, and $4 US discount voucher for new Ali-Express customers https://www.aliexpress.com/item/Free-shipping-Celestron-astronomical-telescope-eyepiece-double-binocular-head-clear-binoculars-special-accessories/32857924895.html?spm=a2g0s.9042311.0.0.6d9f4c4dmNVhwa I also bought 2x 23mm 62degree eyepieces for £6.60p / $12.20 Au https://www.aliexpress.com/item/SVBONY-Aspheric-Eyepiece-Telescope-HD-Wide-Angle-62-Degree-Lens-4-10-23mm-Fully-Coated-for/32788041500.html?spm=a2g0s.9042311.0.0.378d4c4dckvHEL Focal reducers are also available - but I am going to wait and see before buying https://www.aliexpress.com/item/SVBONY-1-25-Focal-Reducer-X-0-5-for-Astronomical-Telescope-Thread-M28x0-6-for-Astronomy/32809751148.html?spm=a2g0s.8937460.0.0.57ed2e0eIxkh3j I don't expect these to be the best kit available, but the package should light up the views of the moon on our little 76x700 Newtonian travel scope, and on Jupiter through the 200p Dob.
  4. Get anything but the £21 Seben 7.5-22.5mm Zoom eyepiece. They are made with plastic internal parts, including the bottom two lenses in the Zoom mechanism.
  5. I have this when using doubled up moon filters, which is most of the time. It appears as a reflection of my eye ball. Either 2x polarised filters on the moon, or 1x ND and 1x purple tinted moon filter on Jupiter can cause the problem. It could be a combination of the filters and the eyepiece. I have an 11mm ES 82 degree, but I can't remember which eyepiece causes the problem, or whether it was with, or without the 2x barlow. The solution was to move my eye position nearer to the eyepiece, mount the second filter further away from the first on the 2"-1.25" adaptor, then simply to try to ignore it. Either way, it doesn't bother me any more.
  6. It will be this one. https://www.amazon.co.uk/AmazonBasics-Tripod-Pistol-Inches-Adjustable/dp/B00CF1LS94/ref=sr_1_sc_1?s=electronics&ie=UTF8&qid=1479339889&sr=1-1-spell&keywords=tripod+pistrol+grip I got the Ravello branded version for £43 on a special offer which was highlighted on this forum. It works well, and feels solid with the Revelation 15 x 70's, so it will be fine with the OP's 20x 50's
  7. I bought an 8mm BST late in the game after the positive recommendations here. It's horses for courses. Initially I didn't like it due to the blackouts. I was finding it difficult to get into a comfortable viewing position with the eyepiece. It seems to be better now that I am used to it. Note: Alan will take a customer return back for a full refund if you don't like the eyepiece and send it back "as new" no questions asked - you pay postage. But if I have a Celestron X-cell LX that works, and you are happy with it, why change a winning formula. Trying other peoples gear out might help you to determine what suits your needs, and what is comfortable on the eye. Some people like the BST's, some like Televue & Pentax. For me the Explore Scientific 82 degrees are my favourite eyepieces. If you ask ten people, you will get 10 different answers.
  8. I have one, it is a good enough eyepiece once the scope has been collimated properly. I used mine in the 200p Dob f5.9 as a tester before getting the 6mm Delos. Then I moved it on to use with the 3-inch refractor f9, and here the scope was the weak link until I repaired the focus tube. The 6mm works well now that I have the 2nd hand metal TAL focuser fitted as a replacement to the rubbish plastic tube effort. Good collimation seems to be much more critical with these EP's. The 66-degree view is nice to have at higher magnification on a manual AZ type push/pull mount.
  9. Go for the ES 11mm, the extra 22 degree view is free. I have the 11mm ES 82o which I use at 109x / and barlowed to 240x in the 200p dob. The ES 82 is excellent. And comparable to the 6mm Delos I use at 200x Eventually I plan to buy the 6.7 ES (or 14mm barlowed) to replace the 6mm Delos.
  10. This has been the best I have seen it in over 12-months. It's nice to be back out again.
  11. A blue tint helps. I bought a blue/purple tinted moon filter from amazon - it was weak as water for the moon, but great for Jupiter. The blue tint tends to bring out the brown bands, and darken the red spot for better contrast. It works really well on the 8" Dob, along with a single polarised filter to dim the view. If I need to stop down the brightness even more, there is the option of fitting a second polarised filter, or replacing the end cap onto the tube, minus the 2" inspection hatch (or whatever it is called) I have tried the no filter method to avoid the many layers of glass - but always end up with retina burn.
  12. The top lens is glass - but the 2x movable lenses are definitely plastic, held in by a cheap plastic collet - as above. The zoom assembly has a little bit of backlash - but is well made otherwise. It is a shame that they used plastic for the most important components - one wipe with a lens cloth and they are scratched beyond repair. This is £20 I could have spent elsewhere with better results.
  13. I have a 3" reflector 700mm x 76mm, and can sometimes make out the 2x brown coloured bands on Jupiter, but nothing else. You are lucky to be able to see the red spot. I need to use the 200P dob for the finer detail up to 180x magnification. The 3" can only manage 90x mag with a crystal clear image. Once near to 100ish magnification, the 3" starts to go blurry, and the tripod vibrates too much for a crystal clear view. At 400mm focal length, your 10mm will give you 40x mag. To get up to 80x - 100x, you will need a 5mm to 4mm eyepeice (or barlow the 10mm) I would invest in a decent eyepiece which can also be used on your next scope.
  14. The best view I ever had revealed the surface shading (which looked like an outline of Africa), with lighter patches visible at the poles. I can't be sure - but the detailed view was likely to be at 165x mag. My last view of Mars was on 11th March 2013, at 240x mag. I can still remember being disappointed at the lack of detail due to the unfavourable seeing conditions. Size isn't everything. The 6mm should be good enough for Mars. The 4,7 will come into it's own for the moon, and for the twice a year occasions when the seeing conditions allow. e.g. Jupiter can be stunning for 2 seconds at 240x if you wait long enough.
  15. My apologies, I was away checking my 2.5x barlow when you replied Goat. The Baader should be a good-un with the removable 1.3x element.
