  1. I think the problem might be the exit pupil of the 40mm Eyepiece. Exit pupil = focal length of eyepiece/F-ratio in your case 40/5 = 8mm. Since you probably not are a young little boy, your pupil can not dilate to more than maybe 5-6mm. therefore your missing some of the light and maybe field of view?
  2. I have an SW ED 2x barlow on the way. I will try using it with my 500D and report back.
  3. Thank you very much Moonshane, John and Matt I ended up with the 9mm T6 Nagler. And I am considering the Aero or Swan at about 40mm for use as a finder and of course for widefield.
  4. I am leaning towards an 11 or 9mm T6 Nagler because of the large AFOV. It will provide 109x and 133x 0.71 and 0.59 degrees. The price is £120 which is quite good I think, the seller says they have had little use, like new. Thanks again for the help
  5. If you do not want tracking or Goto you can't go wrong with a 6" or 8" dob. Dobsonians - Skywatcher Skyliner 150P Dobsonian Is £179 from FLO, then you have some money to spare, that can go towards some good eyepieces. Here are some videos you can see it in action: YouTube - Jupiter Through Skywatcher Skyliner 150p Dobsonian Telescope I have one 150P arriving tomorrow and i will write up some impressions over the weekend. Alternatively you have the Heritage, but then you need a table to put it onto, and it does not look as solid.
  6. Ah I see, you need to have 50 posts to be able to see the sales area I think. I have PMed you instead

  8. bus_ter I can sell you my unused Synscan v 3 handset I will flash it with alt-az firmware to. See this thread for more info: http://stargazerslounge.com/sale/113497-heq-5-goto-upgrade-kit-adm-dual-saddle.html
  9. Thanks for the input Moonshane. I will post an ad in the wanted section. To confuse myself and others some more I found an ad for a person selling a TeleVue Panoptic 22mm localy for about £80 here in Norway. It is a 1.25" fitting and a AFOV 68. It will be about 55x and a 1.25 degrees TFOV. Are the Panoptics as good as they seem? In comparison to the Swans? £90 locally seems like quite a bargain.
  10. I have a Skywatcher Skyliner 150P F8 dob on its way to me. I ended up with it because it is easier smaller and cheaper. I will write up a review after next week. The reflector you have currently is it on an alt-az mount (left/right up/down) or an equatorial mount?
  11. I am no expert in this, but the shorter tube Cheshire tools are often listed as for refractors. The Newtonian ones seems to have a longer black tube. I just ordered this Collimation - Cheshire Collimating Eyepiece from Green Witch Astronomy as FLO won't ship to Norway.
  12. I have been quoted £140 for The Skywatcher Panaview 38mm 70 AFOV eyepiece which I think is a bit to expensive. Wish I had a FLO in Norway The Aero series is probably even more expensive here I have also been looking at the William Optics SWAN 40mm 2" 70 AFOV eyepiece it costs just $118 directly from Taiwan, about £93 including Norwegian VAT . That Eyepiece would yield a 30x magnification and a TFOV of 2.33 degrees and an exit pupil of 5mm. I have heard of people who say they can see the secondary if you use to low magnification, do you think this eyepiece will work in the 150p F8?
  13. Thanks for the answers. Sorry about hijacking your thread Rob. I have made a separate thread here: http://stargazerslounge.com/equipment-help/114838-150mm-f8-dobsonian-eyepiece-conundrum.html
  14. I have a Skywatcher Skyliner 150P Dobsonian on its way to me from Germany. Previously I had an Skywatcher ED80 F7.5 which I now sold because I enjoy my visual observing and occasional planetary imaging more than the long exposure more tracking sensitive deep sky work. I had an old black Heq5 Syntrek which I mostly used manually(i.e without power), and that was kind of hard to say the least considering it is not meant for manual work. Also it had the black synta grease which freeze here in the cold winter nights of Norway. Enough of that With the ED80 I sold a Skywatcher 28mm LET 2" eyepiece with 55 degrees apparent field of view. That provided me with a 22x magnification and a true field of view of 2.57 degrees. I loved the view of the double cluster, that is the largest AFOV I have ever looked into I also have Vixen NLV in 12mm, 9mm and 6mm which with the ED80 provided me with 50x, 67x and 100x and a true field of view of 1, 0.75 and 0.5 degrees. With the 150P they provide 100x, 134x and 200x with a TFOV of 0.5, 0.38 and 0.23 degrees. I enjoyed Jupiter at 100x last fall and could see both equatorial belts, although not in very much detail. I now have a Skywatcher 2x ED Barlow, therefore my logic is that I can sell the Vixen NLV 6mm and just Barlow the 12mm. I am not sure if I will have any use for the 9mm either, with 2x it will give me 268x which sure must be to large magnification for any thing useful with a dob? I have been on the lookout for a 2" eyepiece that will give me as low magnification and therefore large TFOV as possible with the 150P. I have been considering the Moonfish 2" 30mm 80AFOV clone after seeing a good review in Sky at night. But I have heard many people recommending a smaller AFOV with better optical qualities than a large one. At the end I have quoted the reply's I got in http://stargazerslounge.com/equipment-reviews/114787-ethos-13mm-first-light.html thread but I figured it is better to start a new one, than to threadjack Rob's thread.
  15. Thanks for the quick answer, looks like I have to take a look into the Hyperion series then. Thanks again, Julius
  16. Is it just me, or does it looks like Jupiter is bulging in and out of the monitor? Maybe some kind of optical illusion, or my glasses really needs changing.
  17. The Saga continues Kathleen was right on the money The illuminated guiding diagonal reticle is focused using a helical focuser and it can be moved to the little guide scope. It seems like it is missing a focuser for the main OTA.
  18. Excellent review Rob Could you comment a bit on the Moonfish 80 degrees field of view vs the Ethos 100? (As a kind of low cost alternative to the Ethos, maybe a bit of a stretch there ). I was impressed by my Skywatcher 28mm LET 55 degrees eyepiece With my ED80 it felt like the sky was around me, not trough a hole.
  19. Nice low price can't go wrong with that
  20. That sounds very plausible, Thanks Kathleen I will update when I get more pictures and answers.
  21. Interesting Kathleen I think you might be onto something. It should be replacable with a standard Crayford focuser then, if the tube uses a standard thread.
