I image from a surburban location approximately 10 miles SE of the centre of London. Light pollution is very bad (see image below looking South taken from the loft window on a typical winters night) and at best on a good night mag 3.75 stars are just visible. To determine my Naked Eye Limiting Magnitude (NELM) I try and count the number of stars I can see within the Great Square of Pegasus (see table below). From my home I ocassionally kid myself that I can see 1 star. My local horizons are also poor due to trees and roofs so most of my imaging tends to be NE to E at higher than 30degs from the horizon. I image using a portable setup from the end of my garden. Once in a while I will join a group of fellow imagers for a weekend camp at darker sites - typically within a 50mile radius of London. The equipment that I use to image is fairly basic consisting of a couple of inexpensive refractors, a modified webcam (self modded) for guiding, an entry level cooled CCD camera for imaging with a set of LRGB & Ha filters on a manual filter wheel and an EQ6 computerized goto mount. Pictures of my current imaging setup can be seen below.

The images below show my current imaging setup. When I started astrophotography my first scope was a Russian built Tal-2m 6-inch, F8 reflector on a pedastal mount with RA drive only. I imaged using a Toucam Webcam. I then modified this myself for long exposure photography and subsequently upgraded the CCD chip to a much more sensitive Black and White sony chip. (I actually still use this camera as my guider camera). My next acquisition was a EQ6-Pro German Equatorial Mount with ED80 and ZS66 (mounted side-by-side on a dual mount bar). I also purchased a 2nd hand Atik16ic CCD camera & set of LRGB filters.
