The polar illuminator adapter...

This adapter compensates for a lack in the Star-Adventurer and Star-Adventurer Mini mounts.

Indeed, the illuminator provided with the mount is usable when no instrument is attached thereto.
The alignment is likely to be significantly affected when mounting the "L"-bracket + counter-weight + camera.
Unfortunately, once the "L" bracket mounted, it is not possible to put the polar illuminator in the axis of the polar scope.

This is why I designed and 3Dprinted this adapter that fits into the slot of the "L"-bracket and that is positioned in the center of the viewfinder.
The illuminator is then placed in the adapter. The cap can also be placed to close the adapter.

- 1 steel scew (grip blocking)

Polemaster and HEQ dovetail not included.

The adapter is available in glow-in-dark color (white at daylight).

Declination setting circle...

On one side : graduations sticked on the rotating-setting ring.
The disc is inserted on the Kodak screw of the declination ring with downward coordinates.
This new version is removable (the disc isn't sticked on the axis).
The overall thickness of the disc is around 2 mm.

When the disc is in place, you can rotate the coordinate ring. The ring is slightly tightened and stays in position.
Don't forget to stick the marker on the body of the declination axis, in front of the declination setting circle.

You can fix your telescope or telephoto lens to the declination axis, as you usually do.

The precision setting scale allows an accuracy of 0.5° (beyond if you have good eyes...).

 The kit includes :
- 1 declination settng circle, ready to insert on the DEC axis,
- 1 precision scale, ready to stick on the DEC axis's body.
The L-bracket isn't included

The declination setting circle rotates as you rotate the declination axis.
Once a refecence object is pointed, you can rotate the declination ring to set its declination coordinate.

The polarscope adapter for right angle viewfinder...

The adapter is constitued of one 3D-printed piece (material : PLA) and 3 nylon screws.

The metal latitude blocking lever...

If you own a Star-Adventurer mount, you may have encountered
tightening and latitude locking problems, due to the weakness of
the original plastic lever.
Here is the solution : a replacing metal lever.

Here, the metal replacing lever :
- the M6 nut is made of steel,
- the lever is made of aluminium.
 

dismounted replacing lever

Left : dismounted replacing lever.
Right : comparison between original and replacing levers.

The teeth of the original lever's nut offer few grip and already show wear signs from the first use.

The metal nut of the replacing lever is much more resistant. The teeth of the metal lever are more resistant as well.

4 washers are supplied with the metal lever. It may be necessary to place one or more washers between the lever and the mount for the tightening to be effective, depending on the version of your mount.
