Selling Astrosky 11" f/5 dob - one and only offer
Posted: Tue Dec 05, 2006 2:11 am
Ok guys, I only use this scope once and that's it. Basically just to check that everything works well.
Now this is an Astrosky 11" f/5 truss tube with a mirror from WodenOptics. This scope took 11 months to reach. Unfortunately during that 11 months, my observation style has moved to video astronomy, so I prefer a setup that is small and could track. This scope, though wonderful, does not suit my observing style anymore.
I think the pictures below describe the quality of the finishing better than I could. The mirror came without any centering circle (I told him I will do it myself), so I purposely order the centering triangle from Jim Fly of Cats collimation. Why from Jim Fly? Because his centering template is very accurate and the triangle can be use with a laser collimator. Or better still, if you are very critical on collimation, you can order Jim Fly's collimation tools. That to me are the ultimate tools. With his centering triangle there, you get best of both worlds. And you can trust me on placing it accurately at the center (I don't trust any optic maker to do this)
Now here are some of the specs of the scope
Focuser: Dual rate Moonlite 2 " focuser
Finder : Telrad
Secondary : 1/20 wave Antares secondary with dew heater
Primary : Woden Optics with strehl ratio 0.971 and PV 1/10.68. Mirror comes with a certification.
DSC : Sky commander with 4000 tic encoders for you to find objects easily
Also comes with a shroud.
Dimension of mirror box inside the rocker box : 19" x 19" x 19"
Height of the eyepiece at Zenith : about 57".
The scope movement and balance is very good. Both the alt-azi movement is "just smooth" but not so smooth until there is no friction. That to me is the best.
Unlike some other scopes, the secondary cage can be placed into the mirror box for transport.
It took me a lot of hassle to get this scope here. I hope whoever who bought it will give it some good use. I tried it once at Dempsey, absolutely magical views. For the money I paid, I really can't complain.
The scope, including upgrades, sky commander, shipping, GST, insurance cost approx USD$2450. How much am I selling? Cheap..you can take it for SGD$2200. You work out the sum and you know how much you had save for an essentially brand new scope. Not to mention you save on the waiting time which is a real nuisance.
I let the pictures speak for iitself....if interested, PM me. No tyre kickers please.
