Last year, I traded for a classic scope, a 94mm f/16 achromat made by Negretti and Zambra, from the late 1800s with optics made by Broadhurst and Clarkson.  The scope had two support rods connected to the OTA that were designed to fit into an alt az mount.  Since the mount was not included with the scope, I needed some way to mount it on a GEM.

 

I contacted Mark Turner at Moonraker, who is an expert at restoration as well as making wild scopes.  Things started as reversibly removing the hardware, but that uncovered paint irregularities and required a new paint job.  The scope had no finder, no dew shield, no rings, counterweight, etc. so these were added.  The colors of the rings and other new accessories are not an exact match to the brass because of environmental regulations, but as time goes on the two colors will become more similar.

 

At the same time, Moonraker was partnering with Paul Cruickshank-Inns, a master craftsman to make a Delta Pod, a beautiful and wild looking tripod tall enough for many classic scopes.  They made the tripod match the scope, and added an adapter for an AP Mach1 GTO on top.  That will allow me to use other mounts through adapters.  An eyepiece tray is being commissioned for the middle of the tripod.

 

First light was tonight.  The tripod worked wonderfully.  The scope looks like it has great potential.  However, there is a substantial amount of astigmatism that did not fully respond to collimation, and therefore the lens elements may need to be adjusted.  Cruising the sky with a 32mm Brandon at 47x was quite nice.  Jupiter looked decent at 125x, but the combination of mediocre seeing plus the aberrations including astigmatism made for a decent but not outstanding image.  I look forward to getting the lens adjusted and trying other mounts and scopes on the tripod.  The focuser works "backwards" like many of the old scopes.  Mark generously gave me some old classic eyepieces that I want to try after the lens is fixed.

 

Moonraker threads are all about photos, which are attached below.  You can see more photos here:

On the site, you can see that Mark is restoring more vintage scopes like this one http://www.cloudynig...ping/?p=7126565 .  He is an amazing artisan and is delightful to work with.  If you need a classic design, look no further.  Thanks Mark!

More photos.  The tripod is better with less light (sorry about the clutter; the packing material is for selling enough things so I could afford this!).

So you are the owner of the Delta Pod Derek?!  Beautiful combination.   :cool:  :waytogo:   Looks like the 100+ years of difference between the scope, mount and tripod did not matter - they look made for each other.   :grin:

Congratulations, I am sure you will enjoy it.  Well done to Mark also - he's a true artist.  I enjoy a 94mm Brandon/Christen triplet turned Moonraker myself lots.

Hi Robert:

 

I know you have posted it somewhere, but can you link or post a photo of your Moonraker?

 

For Jeremy, I thought of anodizing the mount pieces instead of using brass, but it would be expensive and I don't think I want to have that in case I ever sell the mount.

Derek - A superb looking set-up.  I'm very curious about your scope for several reasons.

In the past, I've seen a couple  of these scopes that were simply re-badged 

T. Cooke telescopes.

 

The engraving on the draw tube pre-dates the Broadhurst Clarkson period, yet the engraving on the

lens cell is from a later period (if I'm looking at the correct for sale add for this scope) .

I wonder if your scope started out as one of the Cooke telescopes and then for what ever reason

it was fitted later on in life with a Broadhurst Clarkson lens and cell.

Elegant indeed. My first impression was that it was a telescope and mount belonging to Captain Nemo.

Hi Rutilus:

 

I am not familiar with the history of these scopes in the same way you are.  It is quite interesting what you say.  I can send you more info by PM if you need it.  I am not sure if I can get any more info on the scope.
