I needed to gain some in-travel when using a Delos 14 on my Vixen SD103s that is fitted with a clicklock and WO 2 inch diagonal.
Every other eyepiece I have works fine but not this 14mm Delos
(or the 17.3mm Delos , which I did own but sold on when I upgraded to a 22 Nagler).

This low profile adapter gains nearly 10mm from the standard deep shoulder adapters and solves the problem.

Well made and with both the metal grub screw and 3 nylon lock screws round the circumference to mount full time to the eyepiece (I only need it for this one lens. )
Used this way remove the metal thumbscrew.
The pack included the hex key for the metal grub screw. No need to tighten these screws too high just enough to grip gently.

The adapter sits very firmly onto the eyepiece and resists twisting or lifting when adjusting the eyecup setting ring on the Delos

The included 2 inch end cover for the adapter is a nice addition.

I got the last of the old stock and see the price has jumped a fair bit now (the Brexit effect no doubt) but the quality is very high if you need this solution.

Purchased to fit onto my 1.25 diagonal as both by scopes have Baader steel track focusers. Really solid bit of kit and has the advantage of securing with a grub screw. Now here is the reason for 4 stars, the quality of the grub is rubbish, when tightening with little torque it rounded out and took ages to remove.

This is a perfect fit for the Morpheus eyepieces if you also happen to be using a Hyperion Aspheric 2" eyepiece as it makes the two eyepieces become parfocal. The Morpheus series unfortunately does not have any eyepieces longer than 17,5mm, so if you want a wide field eyepiece from Baader the Hyperion Aspheric 31mm or 36mm are the closest match. The Morpheus body is a two step fit with both 1,25" and 2" adapters, but the 2" sinks the eyepiece deep into the focuser, so you have to refocus quite a bit when changing from the Aspheric. Mount the Pushfix Adapter, as this adapter is really called in the Baader catalogue, permanently on the Morpheus and the two eyepieces becomes almost perfectly parfocal requiring only a minor adjustment on the focuser.

I love these adapters as you can fix them permanently to your 1.25" eyepiece barrel via a supplied grub screw. They also come with a 2" end cap so you dont need to worry about finding an end cap to put on when not in use. In the winter, when wearing gloves, I don't want to be messing with adapters and taking them on and off (risking dropping something), and these are the perfect solution! (Also note that the pictured thumb screw can be removed if using the grub screw as it is redundant). Highly recommended.
