Due to an unexpected upgrade I am (sadly) putting my much loved 10" dob on the market. This scope is barely 7 months old, purchased from Andrew's Communications in late March this year, first light was 1st of April. This OTA has a white enamel finish, and by all accounts has a superior quality and thickness with regards the paintjob on the tube, according to comments made directly to me by owners of other GSO dobs that were purchased prior to mine.

Included with this sale is a 32mm (2" barrel) eyepiece for wider angle views, plus one each of 15mm and 9mm Plossl ep's (1.25"), I'll include extra goodies as well, such as a laser collimation tool, and the custom fit foam dew shield that I made specifically to fit this scope.

But wait! There's more ...... :P (looking for steak knives....)

Being the Deluxe version it came with a Crayford focusser rather than the standard rack and pinion type, as well as a mirror cooling fan, and a right angle / correct image finder scope. I have upgraded the fan to a more efficient unit which I bought brand new, one that has more aggressively designed fan blades and so it pumps more air and cools faster than the original fan.

I have modified the finder scope with my own custom dew heater (and custom power plug), which is not really removable from the finder and I was therefore intending to keep the right angle finder and include an 8x 50mm "straight through" finderscope (silvery coloured) instead. If someone particularly wants the right angle finder we can possibly work something out.

This scope is in excellent condition, it lives in my lounge room when not outside observing, and it has always performed well for me. Most IIS'ers are aware of the reputation that the GSO mirrors have for great performance at such a reasonable price: I have easily differentiated the 5th and 6th stars in the Orion Trapezium from my very light polluted front driveway, likewise I have observed Neptune and Uranus (in fact every planet except Pluto - now a moot argument) from my back yard in the same suburban location. With dark skies and better seeing Pluto is also within grasp of this scope. With a 10" primary mirror it gathers approximately one and a half times as much light as an 8" reflector, and around two and 3/4 times as much light as a 6".

The dob base has a few nicks and scrapes in the black laminate material. The azimuth rotation mechanism has been modified with "milk bottle" washers to make it move more freely and smoothly. I had modified it with a lazy susan bearing but found that it moved too freely in that it would literally swing in the breeze, so I've de-modded it again in that respect.

Photo's will follow asap (I'm at work at present, the dob isn't) but I am listing this here now, and for the next couple of days to see if there are any takers - if not I'll probably list it on ebay this week.

I do have the box and packaging for the OTA and can send it all by courier - no idea of cost except it cost me $70 to have Andrew's send it up to me here, an hour north of Brisbane. We can arrange something for me to deliver it to within an hour or so of my location if required. Viewing demo's can be arranged if the clouds ever clear! :lol:

Asking price? $500, plus delivery / courier / whatever if required.

In the event of multiple prospective buyers the person with first posting to this thread wins, follow up with a pm to me if you like but post here first.

Cheers folks!

Glad you're interested Tj ... this IS priced to sell, and as much as I'd love to keep it (as would my brother, shame he can't afford it at present!) the truth is the money is already spent and it's time to pay the piper! Let me know asap re your finances Tj.

Anyone else who is seriously interested please get your name down now by posting a reply, in case the list grows fast you may want to be in early.

While I think of it the main mirror is made of BK7 glass, which is apparently pretty good for this kind of thing, and is rated at 1/12th wave accuracy - all I know is the view looks damn good at the business end! The OTA has focal length of 1250mm, making it an f5 scope - fast, but not too fast! The focusser is a 2" Crayford (much smoother and easier than a rack and pinion to reach and hold good focus) and comes with a 2" to 1.25" adaptor so between these you can use any standard sized eyepiece (most of you would already know that I guess).

Here's a quick pic of the dob taken out the back yard one night, also a pic of the moon I took through the eyepiece - let me tell you I am NOT an astrophotographer by any means, but the scope did itself proud I feel, being hampered by me at the camera! :lol:

With luck I'll post more pics later this afternoon of the ep's, etc .... I've just come home from work and I need a few hours sleep first.
:zzz:

I'd love it Steve, but I'd have to move the mirror forward ;)

Ok ... as promised more images .....

Scope from left and right, with and without my dewshield.

Also close up of focusser and finder.....

NOTE: the focusser pictured is my 10:1 fine focus Crayford, the scope will be sold with the original Crayford that it came with, ie it looks exactly the same except that it does not have the little black additional knob on the right hand side as seen here in this pic, also I am keeping my Telrad so the base here (black rectangle between focusser and finderscope) will be removed prior to sale.

There's alsp a pic of the original cooling fan (black), and the twin brother of the upgraded fan that I added, and that does come with the scope (orange blades).

This is on hold for 24 hours .... I had offered this to my brother in Alice Springs (WONDERFUL skies), initially logistics seemed to preclude the sale but I have just had 2 phone calls from him, things may have changed.

Consider this as on hold for a day, not sale pending ...... I'll let you know as soon as I do.

Tj is interested but had not yet committed ..... watch this space.

(24 hours later...)

:welcome:

Sorry folks I do apologise for the "delay" ...... family is family, and I had to give my brother Phil the opportunity to work some things out and see if he could afford it.

This is the situation: I would really love to keep this scope :screwy:, but it's hard to justify owning 2 dobs of similar size, and I do have a debt that I need to pay asap. My brother has offered to pay the scope off over 3 weeks, but he made me promise that if I can sell it for the fast one-off payment that I really want (need), to go ahead and sell it elsewhere.

So .... I'm looking for a firm committment here, price is $500 not negotiable, and I've had plenty of feedback as to how good a price that is, especially considering what's included in the sale. If I have no definite takers by 8pm Wednesday night (that's this week, the 8th) I'll go ahead and accept my brothers layby plan instead. :doh:

Any questions please pm me or post here, I'll try to respond asap.
:thumbsup:

Tj and Tigion are you "interested" or are you "buying"? As you guys did post your interest here you have 1st & 2nd opportunity, but I stress I do need an answer asap. Anyone else who is ready to commit to buying please post here right away, if they decline, or I don't hear from them soon, then the next firm offer gets the goodies.

I believe I'm being as fair as possible, and offering a great package at a very good price, so please excuse the fact that I seem to be rushing this sale. If I could easily afford to hold off a while, the truth is that I wouldn't be selling it at all. :P

I hope to see this go to someone who will gain as much pleasure from it as I have over the last 7 months. Someone ....... Anyone ....... please adopt my beloved scope!
