102mm achro for cheap
Posted 02 July 2013 - 06:25 PM
102mm NexStar GT $119 shipped!
Holy smokes, Batman! This is one good deal. I don't need a 4" achro right now, thank you, and F/9.8 is a little too long for my preference, but how often does a fellow see a brand new, shipped to your door, 4" refractor with Celestron warranty for $120? We live in interesting times, amigos. Now it comes with almost nothing. There's an attachable dovetail, so not even tube rings, but it is a Vixen style, so pretty universal to mount. You'll need a mount, diagonal(s), eyepieces ... but, if you have those things and want a second scope to putz around with, or have been out of things for a while and need something to play with, without arousing the wife's financial ire, this is the ticket!

Free shipping from Ca. Amazing. My old Burgess 127 is kinda big to set up for short sessions, so I will try the 102. I used to have a 90mm F10 scope and regretted selling it. Frankly I have not been viewing for a while, so maybe the new toy will motivate me. Thanks for posting this great deal on the forum. About as good as the recent 90mm frenzy. :jump:

I put a 2" diagonal in mine for more viewing options.
Now if the clouds.......

In my instance I intend to set this up as a loaner. I have a spare low end 2" diagonal and a 6x30 finder ( I think its an orion). I also have a low end 2" 30mm widefield that will give 33x with over a 2 degree afov and then can sprinkle in 3 plossls,9mm,12.5mm and 17mm. Throw in a 2x barlow and this scope will be able to provide a wide range of viewing options. I'll mount this ota on a cg5 with dual drives. Before loaning out we will have to give whoever a fair amount of basic instruction on using a gem. Bottom line,this will be a great learning scope for someone with a moderate interest level.BTW,if I was'nt using this as a loaner I would still use the same basic arrangement as described,buying what I needed used on either cnights or amart.You can find used 1.25" diagonals often in the 20-30 dollar range. A used finder 30-50mm,with mounting shoe (use a orion/celestron),30-45 bucks and then a wide variety of used eyepieces as cheap as say 20 bucks apiece( meade 4000 chinese plossls,orion sirius plossls,etc) if your patient.

Continuing my education--
What hardware would you suggest as a mount for a Porta II, and what hardware would you suggest to mount the ota on a cg5? A link to a product helps--I'm a visual learner :-)

I've never had or used a porta 11 and cant answer in that regard.However this ota comes with a vixen dovetail which would mount directly to a cg5 or current version of a cg4.

I'm really very pleased with mine. Rings, dovetail, diagonal and finder all from CN classifieds.
My friend, if I'm understanding right, the scope comes with the dovetail but is in need of rings--no? Also, what is that mount in the picture.

The short dovetail that is screwed onto the 102 GT tube is of little use.
Rings and a new longer dovetail attached to the rings let you balance heavier eyepieces and a finder.
The sale scope would need:
+ rings and longer dovetail
+ you already said you need mid-high power eyepieces for lunar viewing
I got a pair of Orion 100mm tube rings and 8-inch dovetail. It's OK on my Porta (original) but sits higher off the ground on an old pier-mounted equatorial mount. Being able to use a 2-inch diagonal and widest field eyepiece (for over 2 degree field of view) makes the scope pretty versatile.

I concur that the built-in dovetail is the pits, and only barely acceptable if you will be using the lightest eyepieces combined with a small plastic-fantastic red dot finder such as is provided in some of these scope packages, and not much more.
I already have a 13" vixen-type dovetail here waiting to be used from a previous order from Agena Astro. But the Orion accessory sale makes these dovetails intriguingly priced: (I was slightly tempted to get an extra one or two but didn't. You already know to factor in shipping, and tax if you are in CA) http://www.telescope...Orion-Doveta... (no affiliation with Orion except for several successful purchases from them over the years)
