Eyepiece/filter case and table

Storing my eyepieces and filters

To store my eyepieces and filters I bought an aluminum camera case with a layer of die-cut foam in the base. These cases are widely available not only from the photographer's shop but also from department stores. I first laid out my eyepieces and filters on the layer of foam, and then started to tear out the pieces of the die-cut foam where I wanted my eyepieces and filters to fit. After that I took a piece of silk cloth, and draped it over the layer do foam. This will prevent small particles of the remaining foam getting onto the eyepieces and filters. I always store the eyepieces with both caps on and keep the filters in their storage boxes. This prevents dust from getting onto the surface of the lenses and filters. I always transport my eyepieces and astro-filters in this case (shockproof). (foto(s) koffer)

Using the eyepieces and filters on the observing location

When I started observing I always had a small garden table with me, to put my eyepieces, filters, books etc onto. During almost every observing session I managed to knock over the table and have my eyepieces and filters lying scattered through the garden. That's why I constructed this small table for my eyepieces, filters, and glasses.

The block that holds the eyepieces is constructed of several layers of plywood glued together. Through this block I drilled 32mm holes using a 32mm wood spade drill bit. After drilling the holes I took a piece of anti-slip mat used in bathrooms. I glued this underneath the plywood block, to serve as a buffer between the eyepieces and the table surface. Finally, the block was bolted to the table.

The box that holds the filters is a small portable tool organizer, available from every D.I.Y. store. I took a block of foam rubber and cut some pieces to the right size and height, using a snap-off blade knife. I then put them into the compartments. Next I cut the aircushion out of a self-seal bubble envelope and cut it into pieces that fitted into the compartments (on top of the foam rubber), the bubble's facing down and the even side facing up. They serve as a buffer between the filters and the foam rubber. Then I put the filters on top of the pieces of aircushion. When I close the lid of the box, the filters are pushed into the foam rubber slightly, so that they can't move anywhere during transport. I still am thinking about gluing a big rectangular piece of the aircushion into the lid of the box.

Tip on cutting foam rubber:
If you want to cut the foam rubber into a specific form, first drench it in water, squeeze out some of the water and quickly put it into the freezer. Get it out of the freezer after some time. Before it starts to de-frost, you can cut it in whatever form you like, using a snap-off blade knife. After that, let it defrost and dry.
I have been using this table for more than a year now. While observing I always put back every single eyepiece or filter that I'm using, before taking a new one from the table. The "eyepiece-block" and the "filter-box" have served me well. I managed to run into the table more than once in the dark. There was no eyepiece or filter that ended up somewhere on the ground. Everything stayed into place. A very good investment!
