Suck or blow

Yeah, wooden roll off seem less dew laden. I was an occasional user of one thats 10 years old and only now showing need of TLC. I only once encountered water on the scope optics when opening up.

As it happens, I ordered an additional dewheater which arrived yesterday. I will try mounting that down by the mirror cell of my Newtonian and leave it on when not observing. I shall see what happens.

I will also start assembling the RPi bits for a longer term project.

Good to know about the RoR. One is under construction at Tacande, not that dew has been an issued there. (The scope has a dew heater band around the optical window but I have never used it.) My RoR has a steel frame holding white foam-filled plastic panels for their thermal properties.

Also collecting bits and pieces. I’ve a tatty old 250mm Meade, a camera with integrated filter wheel, OAG and Lodestar, RPi and Odroid SBCs so far but will need quite a bit more yet, including a UPS, WiFi access point and various bits of software.

When complete (late 2025 or spring 2026) it will be drivable over the interweb thingy. I will likely ask BAA members to act as alpha and beta testers in return for free imaging/photometry/astrometry of objects of their choice. No spectroscopy for some significant time, if ever.
