| review: Satellite LNB Holder abused as Piggy Back Adapter (ATM) (appr. € 16,-) |
If your counter balance axis is turning with RA you can mount additional cameras to it.
This method is called piggybacking a camera.
Here is a cheap way to build an adapter out of a Satellite LNB holder:
The adapter shown is from conrad electronics but should be available in lots of other electronics stores.
At conrad reffer to:
SAT-MULTI-FEED-HALTER UNIVERSAL
Artikel-Nr.: 287938 - 62
The picture is showing two sets.
The front set shows the original intention of the manufacturer.
It's designed to hold two LNBs on one antenna.
The LNBs can either have 40 mm or 23 mm of diameter.
The rear set was reassembled to give a piggyback adapter for 40 mm axis diameter.
That is just perfect for my Fornax 50 mount.
If you assemble the two parts just the other way round you get an adapter for 23 mm axis diameter.
If the your axis is slightly bigger it should work without a problem.
If the axis is slightly smaller you could file or saw several millimeters from the two parts.
I recommend to connect the two adapters with a rigid alluminum plate instead of the included part to give more stability.
Additionally you could then drill the correct holes matching your camera or mounting bracket of the scope.
That's how it looks like when it is finished.
The lower part is carrying the mounting bracket of the Tak FS60C and to the upper part I screwed the piggy-back holder of the HX916.
The telephoto lens is directly mounted to the camera.
Note the little adjustment screw right underneath the camera.
It's used to adjust the camera coaxial with the other scopes.
I think this is a versatile and cheap alternative.
