In my post https://roslistonastronomy.uk/m31-on-the-cheap, Rob commented
“I am now looking forward to your results from the Bird Table Observatory (fits in small spaces), the Chimney Observatory (excellent horizons) and the Picnic Rug Observatory (good on holiday with you)!”
Well, as it happens – – – !
3 or 4 years ago we, and the window-sill observatory had some holidays in the West Country (see http://www.thornett.net/Rosliston/Astrophotography/html/dsos_1-10-16.html and http://www.thornett.net/Rosliston/Astrophotography/html/deep_sky_objects_from_the_west_country_8-10-2015.html)
and in 2016, here are a couple of images of NGC 1499, the California nebula, and M45 from a “bird table observatory”! Admittedly this bird-table was a sawn-off tree trunk converted into a bird-table. Incidentally, a sawn-off tree trunk makes a really good very stable well-damped scope pier, it just takes a while to get to the end product! I also took the opportunity to do a bit of reprocessing.
The previous year we were in Cornwall and here are a couple from the “Picnic Rug Observatory” Again admittedly the rug was spread on a patio table. Anyway here is M33 and M45 again, with a scope this time.
No “Chimney Observatory” as yet though!
