Double Piggyback for Coronado PST
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

My ETX70 riding my Astro-3 mount : all it needed was a leftover piece of aluminium, 2 bolts, a scrap piece of threaded rod and a knob.

The focuser knob cannot be reached when the OTA is pointing upwards: it disappears between the forks.
I used a piece of flexible aquarium air tube [inner diameter 8.5mm], put one end of it in boiling water to soften it and forced it over the focuser knob.

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!

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.
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.
