For the record (my firm used to make four axis turrets that had to operate in high g and vibration environments), castings are the weakest form of metal work even if there are no flaws. Machining from forged billets is the best but costs a lot more. After that, machining from extruded billets like Losmandy does, then machining from cast billets. Last place in strength is machining of cast shapes (not billets).

The forging and extrusion pressures (and heat) makes the metal stronger, which of course means machining is slow and there is more of it. Weakest are castings. Poor quality control makes it worse, of course.

It all comes down to economics, but things like this cost the companies in both replacement costs and reputation, so I sure ES will do right by you.

Yep, ES has your back.  Some of the best customer relations and service I’ve seen.

They replaced an entire EXOS2GT mount for me about a year and a half ago after a motor/gear issue.

I thought I would share my recent attempt at the Flame Nebula, Horsehead Nebula and NGC 2023. You can see my last try about a year ago here.

Captured over 8 nights, from Oct 31 - Nov 8, with a total exposure of just under 20hrs and a waning full moon in Bortle 9+ white Houston skies.  I'm shooting to the exposure limit of the light pollution here in Houston, using the Optolong L-eNhance filter, which is acting as a narrowband h-alpha filter for the red channel of my unmodified EOS RP camera.

Focal length is 864mm and resolution of 1.37 arc-sec/pixel, with PHD2 guiding error between 0.6 - 1.2 and an average of 0.8 arc-sec error, where everything was run on my telescope mounted RPI4 connected to the PMC-Eight via WiFi.  Shot at ISO1250 and between 400 to 600 second exposures.

Hi all, 
      I think members are encouraged to post images taken with this mount.  Sorry if I am wrong.
This is not great but, taken near the centre of a town so a fair amount of light pollution to contend with and with only 40 minutes exposure, it is perhaps not too bad.  A half size image. Some details below if any are interested.  At least it shows what one might be able to be achieved from a dark sky location and longer exposure. (We are not allowed to travel at the moment.)
Cheers,
Ian

This mount, small refractor and camera make a wonderful, portable, imaging system for medium sized fields.

80 mm semi-apo refractor with Teleskop Service (German) 2 inch field flattener.

Sony A7S, 12 megapixel camera at ISO 2000,  15 second exposures to ensure the centre of the galaxy was not over exposed.  Long exposure noise reduction was not used.

Mount aligned with a laser pointer through the sighting tube but I was not wanting to be too precise so that the image would move slowly across the sensor during the total exposure time.  In fact 1.3 pixels movement in each exposure so there was no star trailing and a total of 104 pixels during the imaging period.  This should  remove what Tony Hallas calls 'Color Mottling' and the effects of any hot pixels - in fact none could be seen in the captured image..

Galaxies (M110, M32 as well as M31) and stars separated and processed individually and then recombined to give the final image.

Thanks a lot Wes. It's great to know ES has trust in its customers to assist them to correct known issues. For me, that is a first for mount vendors.

Kudos to ES and much appreciated 

Off to the garage to work on the mount and finish the setup.  I am sure I will have other questions 

Best
Don

Paul, As I mentioned, my Orion .8x FR looks identical to your FF. On my Nikon, I use 2 different T adapters, see attached pics. Both are just attachment adapters. No additional spacing. On the left threads are 42mm (std),,on the right is a “wide” thread 48mm. I use the wide one with the FR. The wider thread helps prevent vignetting. With the wide one I also need one 2 inch extension tube. The 42mm is used with no FR.

Since your T2 adapter has some extension  built in, perhaps a smaller additional extension is required, or a T ring (probably like my wide), with no extension, plus one 2 inch extension. Extension tube kits are available with multiple lengths,  The pic with the camera shows my setup. I would just screw the ext tube on to the telescope.

Hope this helps.  Harry

just to be sure, it is the larger ribbed knob that unscrews ? (before I apply too much force on something unmovable)
