    Visual astronomy in general and an advocate of sketching as an aid to observing.
    I also have a passion for refractors and optics in general, and have a deep interest in the history of amateur astronomy, the astronomers and their scopes and observatories.

  1. There is no doubt in my mind that the feathertouch is far superior to the Tak focuser, but it is pricey. Having said that, the Tak microfocuser isn't that cheap either, but I've found it more than adequate for my own needs. If I ever had the spare funds I would definitely consider a feathertouch replacement, as the telescope itself is definitely worth it.
  2. Yes, it seems to be 81 that might be throwing your focus too far out. 15 should screw directly onto the draw tube and all should be well. I don't know why Takahashi insist on supplying these adapters. I'm sure it would be simpler and cheaper to just have a longer draw tube.
  3. Did you have the extension tubes attached? If so, you'll need to remove them. The set-up should look like the attached picture when a diagonal is used. In this mode the scope should focus pretty much all 1.25" eyepieces. You might like to try and focus on the distant horizon before you aim it at the night sky, at least until you've acquired a finderscope of some sort. It's interesting that you say the latest user manual makes no mention of alcohol! Great scope by the way!!
  4. Have a chat with paulastro. He bought one recently and absolutely loves it, and he wouldn't put up with anything but excellent!

    Refractor upgrade

    You won't miss the extra focal length. The 120ED's will take much higher magnification while still remaining sharp and contrasty. On a clear steady night, the ED will deliver 100X per inch on lunar and some planets such as Mars and Venus. If you like using longer focal length eyepieces then use a SW Delux 2X Barlow in the scope. It won't add false colour or degrade the image in any way. SW Delux barlows are very good quality. I use one on my 100mm Takahashi scope and its razor sharp and the definition is breathtaking.

    Refractor upgrade

    There's no dilemma, It has to be the 120ED! You won't regret it. The 120 ED's optics are in a whole different league.
  7. Looks very pretty and with a Tak prism too!

    Where to mount a red dot finder?

    Yo may be able to order the paint from Nick Hudson at True Technology if the worst ever happened. Hopefully it never will!

    Where to mount a red dot finder?

    I'm not sure how the red dot finders attach to a scope normally, but if they do so by a small dovetail adapter, you could perhaps attach one to the flat surface of your clam shell. By removing the screw protruding from the top of the clam shell you could possibly attach a finder shoe to the shell. If screwing inward from the top of the clam shell be careful that the screw isn't too long or it will scratch that beautiful paintwork.
  10. What a splendid looking instrument! The versatility and ease of use of modern short 4" apo's often leaves me wondering why anyone would bother with anything else - but I am so obviously biased. It wouldn't surprise me if your new esprite soon becomes your all time favourite scope.
  11. If you like your Canon lens, you might consider refractors from Takahashi or Borg, as they use high end optics from Canon Optron.

    Do we see what we expect to see?

    Its very easy to delude ourselves and imagine subtle detail that's on the edge of discernibility. It's best not to view dso images or drawings made by others prior to observing the same object ourselves. Even checking out the longitude of the central meridian of Mars prior to observation can influence our hopes and imagination, so that we see what we expect to see. However, really studying an object, even a lunar crater that thousands of observers have viewed countless times, you can make your own personal discoveries. I've seen rills that don't show in lunar orbiter images and which seasoned lunar observers have never seen, even in much larger scopes. Yet despite claims that they don't exist or that they are merely an alignment of features too small for my scope to see, they have- after my sketches came to light- been imaged by another amateur. Then other observers intrigued by the suggestion of these rill systems in the crater Werner, have searched through orbiter images and eventually found the rills, though very poorly displayed due to the high angle of the Sun. So if you do see something that others have not seen, or that some dispute the reality of, don't be too quick to doubt yourself as there's a high probability you are right.
  13. As a purely visual observer I'd say go for the 80ED. It's a very nice scope optically, and as far as star images and sharpens of image it will surpass the 130 you have, although the 130 has a significant advantage in light grasp.
  14. It's a difficult choice, and I can imagine the temptation to go for the heavier scope because its more readily available. All id like to add to your quandry is that i had two great refractors some time back, a largeish aperture but heavyish ED apo and a light weight but small ED apo. I found that after buying the smaller scope I would use the little grab and go more often and for longer periods. It never failed to impress me despite its diminutive size! Perhaps the lighter scope may prove to be the wiser option in the long run?!
