    Default 20110322 Doubles Night



    Tue 22/03/2011 20:00 - 21:45 UT
    53ºN, 2ºW
    Gear: Sky-Watcher 200P
    Seeing: 3/5, Transparency: 4/5

    20:00 - Set up & P.A. Then coll check against Sirius @ 10mm, no adjustment necessary. Start cool-down. Tea (pork and roast veg, for those keeping tabs - always use maple syrup for your parsnips…)!

    20:35 - General 25mm manual tour. Had been hoping for M31 and Saturn tonight, but our restricted back garden view had other ideas - trees and buildings ahoy!

    20:58 - Split Castor beautifully @ 10mm w/ 2x. Nic was very impressed.

    21:10 - In honour of her dear dad, the late Paul Doherty, astronomical artist and guitar hero, I broke out the old 26mm Televue. Shockingly in need of a clean, this EP still produced crystal clear views, with excellent colour truth. Resumed manual tour.

    21:17 - Split eta Cas @ 10mm, and even @ 26mm, such is the quality of the Televue.

    21:45 - Could just split theta Aur @ 10mm w/ 2x, but the seeing was going off and this was none too easy.

    Called it a successful night. Thanks for reading.
    Scope: Sky-Watcher Explorer 200P (200mm f/5 Newt GEM)
    EPs: S-W 2x Barlow, S-W 10 & 25mm, Tele Vue 26mm, Or 12.5mm, Or 18mm, Charles Frank UWA (needs calibrating to establish focal length)
    Bins: Meade 10x50 7º, Fumoto 8x40 9º
    Cameras: Canon 5D Mk II & Canon 400D

    Great report, Mark!

    I was splitting doubles this week, too, though my main objective was eyepiece testing. It's always nice to have an option for those nights when the moon is washing everything else out.

    Did you see the red color on eta Cass B? I can see it clearly on some telescopes / eyepieces but not in others. Generally, seems to like best a medium magnification, not too low but not too high either. You've also got to try Algieba, it's really pretty.
    Must be wonderful to have a 26 mm Televue. I imagine it's an older eyepiece?

    Doubles are awesome! Didn't think they would be anything special until I first saw one, but now I love them.

    Got a hint of orange out of it - very nice to see.

    It is indeed. I have several others to explore as well, including a semi handmade one (my wife dimly remembers her father putting it together) which comprises an eyepiece with a "Charles Frank Ltd. - Ultra Wide Angle" designation, but sadly no focal length or other markings, attached to a longer than usual extension tube.

    Going to have to figure out my own calibration of that one by comparing it with known focal lengths against the moon.

    I also got to handle a couple of three inch EPs that he used to use on the 16.5" main scope - don't think I'm going to get them to fit my little Sky-Watcher somehow!
    Scope: Sky-Watcher Explorer 200P (200mm f/5 Newt GEM)

    Nice report Mark. I'm a fan of doubles too. I'll take my maple syrup on pancakes though.
