Bobs Knobs

[timelord]

Gooday I'm looking for a set of Bobs Knobs collimation screws to suit a C8 Celestron SCT scope Imperial threads.
Pm if you can help.
Thanx Al.

I believe Bintel sell them.

[timelord]

Yes they usually do but have been out of stock for over 2 months and cant say when they will receive new supplies.

[h0ughy]

shouldn't say this but just go to bobs web site (http://www.bobsknobs.com/) and order them - free world wide shipping and the Aussie dollar is pretty good.

however in saying that i will be a hypocrite and say support your local dealer and contact them again to see if they are due in soon:D

Scopestuff (http://www.scopestuff.com/) in the US is where I got mine, there's a lot of other useful stuff they sell, mine arrived in 10 days from order.:thumbsup:

[timelord]

Thanx guys I'll check them out.

I just got a set for the C9.25 but they were on back order for about 3 months. I think supply may have been low for a while there.

Just checked these guys out. Anyone know if these would suit a 10" GSO Dob? (I got there by clicking the GSO link but they're labelled as LightBridge items when you get there).
$51.00 - #CSK3 - LightBridge 10 & 12" Primary and Secondary Collimation Thumbscrew Sets and Primary Springs

Do Bintel's bob's knobs have primary, secondary and the springs for both? [edit: ok I'm thinking you don't need stiffer springs on the secondary...] It's hard to tell from their website. They're listed as only $29 on the Bintel site, so I'm wondering..

Seems some are plastic and some are steel?

Yes it's hard to support your local guy when they're out of stock for long periods.

Had a look at the Bobs site.. hard to tell which ones would suit my GSO dob, although I'm thinking the Orion ones? Also, they only seem to mention knobs for the secondary? Can you provide a link? Thanks. The free shipping got me.. just noticed that :D

Edit: never mind, found them. They're the LightBridge ones (duh).

[JethroB76]

Thats a great price they're doing on the lightbridge knob/spring set

[programmer]

I think they are $14 cheaper on the Scopestuff site, except... not sure how much postage would be (it's factored into the price on Bob's site) and are they the same, or at least equal quality?

[JethroB76]

It does look to be that way; once the shipping to Oz is factored in the total will probably be similar. I cant imagine quality being much different between the two.

I use common bolts, then glue wing nuts under the heads. Works fine
