Hello all
With the howling wind of a front coming through, using the 10 inch was impossible and seeing would have been awful anyway so wide field imaging it is.
Used the 300mm f2.8 lens, at f3.5, UV/Ir and LPS filters, modded 350C and 7x15 minutes, ISO 400.
Full res. version here http://www.users.on.net/~josiah/catsp7x15minsiso400lps300mmf3.5mod3 50d2.jpg
No matter how strong the wind gusted, the old sampson mount tracked perfectly with such a small, light load, just the lens and guidescope. manually guided as usual.
