Homemade Filterslide Heater

Above you can see my Astrocrumb Filterslide. You can see my Ultrablock filter (top), Variable Polarizing filter (middle), and OIII filter (bottom). My homemade heater consists of three resistor sections combining to produce approx 12W of heat. It works flawlessly and looks fantastic.

The filter slide and heater is stored in a custom made pouch in an aluminum case.
