Dew control

As the humidity in Belgium is very high most of the time, I finally decided to buy a dew controller and a heater for the eyepieces, secondary mirror and the filter slide.  

Installing the Dew Controller

The Dew Controller I ordered is the Quad Channel Digital Dew Controller from Dew Control. The 2m long cable of the dew controller was too short to connect directly from the ServoCat power bar.  To fix this, a connector from the front of the lower cage to the power bar was installed on the telescope.

From the upper cage, I can easily attach the heater strip to the eyepieces.

Installing the filter slide with the Omega Dew Terminator

For the filters, I ordered a new filter slide, with the Astrocrumb Omega Dew Terminator.  The new filter slide has space for 4 filters: my Astronomik CLS filter, and my Lumicon UHC, O-III and H-beta filters. The fact that I will have space for 4 filters will already be a big improvement, as the H-beta filter is hardly used now.

Installing the secondary mirror heater

I ordered the Kendrick standard elliptical secondary mirror heater to keep the secondary mirror free of dew.  The filter is installed easily in the secondary mirror holder of the Obsession telescope.
