Further Comments on the 150mm Esprit
Hi casstony,
Some further comments on the Esprit 150mm. I'm more than happy with it, the finish is excellent, the rack and pin focuser is definitely not a moonlite or feather touch for that matter. Having said that, with the x10 fine control it is adequate, and I don't think I will bother to change it (all my other telescopes have either a feather touch or moonlight). One feature that it does have, is a focuser flick leaver lock, that allows the focuser too hold up to 10Kg, which makes up for any short falls in the focuser (my camera gear weighs 1.5kg). The Optics are just superb with no sign of false colour either visually or photographically, that's what you pay the money for. I did a 10sec exposure on Alpha Centaurus and there was no sign of colour fringing.
The only cropping I need to do when I photographed NGC104, was to remove the border artifact from DeepSkyStacker. Stars to the edge of the field where round, with no sign of astigmatism or chroma. It is early days, but I don't think I will be parting with it any too soon. It is not a replacement for my C11, which I use for DSO's, but as I explained to my wife, a wide angle lens, in other words, a "refractor" telescope you just have to have.
You don't see many secondhand ones on the market, that's got to tell you something about them.
Cheers
Peter
