Just a quickie, I've moved and am relocating my steel pier. So, would postcrete do a decent job for the footing of my steel pier in conjunction with rebar and 14mm threaded bolts? I'd make the hole big enough to cater for the size of the pier base and threads, I'm just purely asking if it will be strong enough as it is designed to hold concrete fence posts up with fence panels in the wind. The alternative is to mix concrete but if postcrete in the right quantity will do the job satisfactorily I'd choose that for convenience.
Thoughts please 🙂
I am only a few weeks into astronomy and started off with a Celestron 9.25" Evo on the standard AZ mount. I guess with hindsight this wasn't the best place to start and also with hindsight I would have done better to have bought a GEM mount. Anyway, lesson learned and at 71 years old I have to speed up the learning process compared to younger enthusiasts I have 2 issues. 1/ Its a pain dragging the scope out into the garden and setting it up every time I think the fickled weather might be obliging. 2/ I now know that the mount I have is useless for long exposures and a wedge is fiddly to get polar aligned.
My question is, though I gather wedges are a PITA to setup etc is if I was to build or buy a pier for the backyard and use my existing mount + a wedge is this a reasonable way to go? Though it's fiddly to set the thing up once set I could leave the mount, wedge, etc covered up and would just need to drop the OTA on when I wanted to use it. Is this reasonable or am I missing something fundamental down near the bottom end of my learning curve
Any advice much appreciated and don't feel you have to spare my feelings
Hi everybody - I wanted to share my experience of designing and building my own observatory. It is a unique octagonal design and offers pros and cons to more common designs often utilised by the amateur community. If you are considering an observatory project, I hope it gives further inspiration and allows you to find a solution that works for your site, skills, budget and observing aspirations. The story is on my website, link here:
Tickets (free) are now available for the Birmingham University "Astronomy in the city" event on 6th March. Sounds like an interesting evening for newcomers like me.
The agenda includes
What to see in the sky this month,
A talk on super novae
Ask the experts
An observing season
And tea and biscuits!
