I would describe myself as a beginner-yet-lifelong enthusiast of the celestial, but have been known to pop what lensed devices I have in a big bag and cycle until the skies darken from Edinburgh's lights.
I fear the weather will make such expeditions foolhardy for some time, but now seems a good day to gauge interest in forming a group to cycle out to somewhere dark as a dark place and look at the Universe, after the new year.
I would guess that the slickest way of doing it would involve a trailer or similar cargo-ness, and many a vacuum flask of hot drinks. I can confirm that's it's possible to ride a bike with an 80mm reflector on your back, but it's a head-bumpy pain in the posterior.
