New Obs Floor

After installing a Pulsar observatory last November I had a lot of problems with condensation and water getting onto the concrete floor. After months of drying out and checking where the water comes from and where it goes I have finally installed the plastic layer and the floor matting this weekend - Easy to install the pre-cut flooring.

Just fitted WRGB LED light strip under the dome rim in my Pulsar observatory. When installed under the dome rim the LEDs cannot be seen directly (except if you sit on the floor) so night vision is not affected. With the hand set any colour can be used and there is a dimmer function as well. So full white light illumination is great for setting up then red for aligning and very dim red or off completely for image acquisition.

Are you using a dehumidifier in the winter months?
This should help with the condensation. I use one on mine, generally from late september to around March and never have a problem with condensation.

Hi Carole
That is good advice. I have installed a dehumidifier. I found that condensation was a big problem initially. It would form on the dome then run down and pool on the shelf which runs 360 degrees around the observatory. Then it would drip down onto the floor and pool there. As you say, adding a dehumidifier stops that problem. I didn't need it during the summer, but I guess when the cold nights arrive later in the month I will need to run it.
The dehumidifier that I am using is on loan from a neighbour so I will need to replace it. Which unit do you use Carole ?

I use this one, DIO, it is a desiccant DH so it will go down to low temperatures, you can also fit a drain to it so the water it collects goes outside, In my case as I have decking it goes directly under the decking, but you would have to find a way to get it outside with a concrete floor. It also has a collection tank but you need to go out and empty it regularly as the DH stops once it is full.

The guy that sells it is an Astronomer and gives good customer service.

I second what Carole says. I've had one for a few years and no problems with it or condensation.
