Double Piggyback for Coronado PST Coronado PST and LX200 are in full operation.
Home With my PST riding high on my LX200 and when the sun is low during the colder period of the year I cannot see the finder window on top of the PST, unless I climb a small ladder.
So on a cloudy day I made this Solar Finder

Two Way spirit Level for Coronado PST on Acuter Merlin Mount The setup procedure of my Acuter Merlin Mount demands that my Coronado PST is perfectly horizontal.
In a caravan shop I bought this nice 2-way spirit level and glued it with double-sided tape on the PST.
My Coronado PST is in full operation.
I use this Jump Start to power my Acuter Merlin Mount.
As the cigarette lighter connector [out of sight on the right] is highly unreliable I installed a new connector [just left of the reflector] and also an ON/OFF switch.
Of course I also provided the Merlin with the same type of connector; I also installed a 12V red LED in the power cord so that I can see that the 12V is actually there.
The problem with the unreliable cigarette lighter connector is that unexpectedly the 12V power to the Acuter Merlin Mount is interrupted due to a bad contact and then the Merlin stops tracking of course.
After that the whole setup procedure for the Merlin has to be redone, which is highly irritating especially when the Sun gets close to trees/buildings and/or clouds are arriving.

This is the dew shield I made for my William Optics Zenithstar 80 ED II APO.
Please note the metal pins in the dew shield: they create diffration spikes, which are great for focusing and also look nice in the image.

This is the diffraction spikes mask I made for my William Optics Zenithstar 80 ED II APO.
In the plumbing department of my local DIY shop I bought a plastic ring which nicely fits in the dew shield I already made for my ED80.
To generate the diffraction spikes I used thin fishing line which gives more delicate spikes than the metal pins I used before.

Flexible USB light
I bought this gadget for almost next to nothing, went to the electronics shop for a red 5 Volt LED and replaced the existing white LED.
Next I installed an ON/OFF switch in the cable and now I have an illuminated keyboard!
This gadget is frequently used in The FIRMAMENT Observatory
Flexible USB light in operation
The flexible USB light with red LED in operation: I used the flash of my Nikon Coolpix 995 for this pic, but I assure you that the red light illuminates the keyboard very nicely!

External WIFI antenna for better reception
I had problems with the internet connection between my backyard observatory and the wireless access point in my home; this connection is vital for my WLAN Remote Controlled Imaging operation.
I bought a wireless USB adapter [Euro 30] and mounted it in a kitchen sieve [bought at Ikea for Euro 1,50].
The reception has vastly improved and it also works fine on campings !
To protect the USB adapter against rain I mounted it in a plastic medicine bottle so now it looks a bit like a lamp.
This connection is essential for remote controlled imaging
