Yes, where I am in suburban Eltham it is almost impossible to get decent seeing due to light pollution and heat pollution from neighbouring roofs except close to the zenith. But at low magnification with lenses can get by for imaging with appropriate filters.
When I get everything working well and I have got up to speed myself will try some serious imaging from a dark sky site. I am still learning.

The Canon 85mm F1.8 for its price is almost as good as an 'L'. All pics shot at F2.0 if I had closed down to F2.8 there would be no CA around the bright stars.

You are right Striker but all I wanted was to see how much red (H alpha) I could get out of F2.0, even at 85mm.

I hope the next time it is with the Hutech modded 5D and just the LPR filter as reflection blue is almost all lost in the nebula filter as it really only passes OIII and H beta.
