I picked up this 44mm sunshade, a USOptics, from Will -

Now I have an ST-10, and it's like a 50mm objective.

This 44mm is right nice, lower profile.

I saw on their website that the new ST-10 is a 37mm objective....


They making the ST-10 smaller now?

It may be time to change out scopes!

Love to get a lower profile scope in fixed 10x..
 
Re: USO 44mm Objectives

OK Then I need to define the objective, my scope diameter at max poiint is 50mm (or 55, b ut bigger than this sunshade.

The inside diameter of the sunshade is 44mm...

The 37mm Objective is an option on the ST10 and SN-3 1.8-10X scopes. It looks like USO is updating info on their site, and there is still lots of info left blank. The specs on the front page of the <span style="font-weight: bold">ST-10 10X</span> are currently blank, so the only way to find-out about the 37mm Objective option is to go to the <span style="font-weight: bold">SN-3 1.8-10X</span>, click on <span style="font-weight: bold">"Options & Upgrades"</span>, click-on <span style="font-weight: bold">"Objective"</span>, then click-on the <span style="font-weight: bold">"Details"</span> button in the "Objective 37mm" box. There you will see:

<span style="font-weight: bold">Type: Objective
Name: 37mm
Price: 0.00
Description
The 37mm objective is optional on the SN-3 1.8-10X and ST10 models. The front of the objective is threaded for use with a sunshade, ARD or optical filter.</span>

Yes, Grasshopper, the <span style="font-weight: bold">Objective diameter refers to the lens diameter</span>, <span style="font-style: italic">not the diameter of the Objective Bell</span>.

Re: USO 44mm Objectives

Hey Arc,
I know what the difference is........your ST10 has the old style non-ERGO objective right (big adjustable objective with the numbering on the back of the assembly)? The shade you got is for the 44mm Ergo that is slimmer.
 
Re: USO 44mm Objectives

The 37mm are very, very nice they let you mount it lower and pull it back closer to you if need. I also love the look they remind me of a modern day MST100.

The CSGW ST10’s look awesome on your setups!

Here’s a photo of mine:

Re: USO 44mm Objectives

I'm sure they'd make you one with the old objective, but now they only offer the "low profile" when using their configuration tool.
Yours is a classic Arc!
