Hi all,
I am now the proud owner of a nearly new deluxe 12" GSO Dob pre-owned by darkplague (Mark).
He has done some major enhancements to the scope and mount and could have a future in retrofitting 10 and 12" Dobs for profit!!
Bad weather overhead of course.
Hope to post a mini review when skies clear.
Very happy,Jan!
Cheers
Doug
Hi ving,
enhancements are:
Tube completely flocked!!(in a nice way)
Good quality handle added to aid motion of tube.
GSO finder replaced with Lumicon RA finder.
Mount completely braced.
All joints sealed.
Cheap bolts and bushes replaced with real chunky stuff!
Suffice to say it's built like a brick you-know-what.
Now if only I could get to look through it...
take a look at the pics.
And darplague, if I've missed anything out let me know.
Cheers
Doug
to the big scope club Doug, I have a 12" LB we both share the same optics and all I can say is WOW!!!
The mods look terrific and certainly add to the scopes performance.
I'm looking forward to your first light report. Cheers, John

Thanks to all of you for the comments.
SA is having some really bad weather, so I've still not had it out under dark skies. It looks like there will be a full moon too by the time things clear up.
Oh well, at least I've got it to play with I suppose
Cheers all

Slight break in the clouds tonight.
The waxing gibbous moon buggered things up a lot.
But, the small break in the clouds gave me an insight into the potential of this scope.
I'll keep you posted.
Cheers
Doug
Still peeing down here in SA (heavy rain since saturday).
Gave me the opportunity to try and smooth out the dob base motion.
In the brief few mins I've had with the scope under the stars,I've found the motion quite sticky and abrasive - especially noticeable with a cheap 6.5mm Andrews EP!!! Darkplague used a TV Panoptic and a couple of Pentax EPs so the dob's motion might not have been as critical with their wide FOVs. But jerking this thing around with the cheapo EPs is no fun.
So I decided to do Iceman's Dob mod. http://www.iceinspace.com.au/index.p...19,116,0,0,1,0
Removed the old white teflon squares and replaced them with the same superslider discs(x6) from Mitre 10 ($11) and 4 milkbottle washers in the above link - darkplague already had a teflon bush installed so not as many milkbottle washers needed.
What a difference
Motion is now silky smooth - I hope this will be evident at the eyepiece when this bloody rain stops!!!
Cheers all
Doug
Hey astronut (john),
Your 12" LB looks like a monster in your avatar picture!!
Is it similar in size to the GSO dobs?
...or did you shrink the suburb!!?
Cheers - hope you're getting better weather than me!
Doug
Hi Doug, A friend in the astro club I belong to has a G.S.O. 12" and side by side they are the same size, though the LB "looks" bigger. Probably because its all white My avatar is actually of someone elses LB. I liked it because of the shroud and background Skies have been clear here, but that big searchlight in the sky has been a pain Can't wait for new moon and point this baby to the planets and D.S.O's again.!!
Guang Shen optics rule
