:mad:Actually, it should be titled 'The Blind Eyeball in the Sky'....Yesterday I upgraded the standard focuser on my SW 10" Dob with a Revelation Two speed Crayford focuser. It was quite a scary thing for me because I'm not a mechanically minded guy, and because of that, I quite often can't see logical solutions to mechanical problems. That's what comes with spending half a life time as a 'people' worker..a detached youth worker actually. Anyway, after much dithering and thoughts of not doing it 'cos I didn't want to b***er it up, I removed the standard focuser and had a cup of tea to calm down...

As I followed the advice received from the good people of this forum, my fingers were trembling as I slowly screwed the new super duper focuser into place and gently packed the gaps round the baseplate with dark foam, presumably to stop spiders crawling in and dying on the mirror !!!. Well...Job done at last AND there was a clear night forecast for later.

Carried the Dob outside and as I waited for the cool down, I sat on a garden chair and marveled at the first clear sky in two months. Binos pressed to my eyes I observed the Orion Nebula in all it's glory and Pleides as well. Both VERY visible to the naked eye....I stole a quick look through the eyepiece (25mm Wide angle lens).....and OH!!! WHAT A DISAPPOINTMENT !!! :mad: The focuser would not focus!!! It wouldn't wind out enough and everything was a blur......anyway I calmed down after a while, the neighbourhood dogs stopped barking and the residents closed their curtains again. With a heavy heart I packed my equipment away and came and scoured the lounge for a solution...if there was one to be found. I'd got visions of screwing the old, clunky standard focuser back on and re selling the Crayford. It turns out, thanks to the knowledge of stargazers in the Lounge, that all I need is an extension tube to allow a bigger wind out in order to achieve focus,which I ordered from FLO not 10 mins ago...and guess what?....you'll never guess in a hundred years!!!...I looked at the long range weather forecast and they are saying ..:clouds2:"CLOUD FOR THE NEXT THREE WEEKS":clouds2:..AAAaaarrrggghhh!!!...I hope YOU have clear skies Mes amis...say a prayer for mine!!!
