Actually it's not new; this has been done for some years now with great success. The only caveat is that since throughput is so low, the total exposure times run rather high for a given final image. You spend a lot more time on a given object. On 11/9/10, Canopus56 <canopus56@yahoo.com> wrote:
The Dec 2010 issue of ST at 72-75 by N. Fleming suggests that useble imaging can be done from an urban location by using narrow band OIII, Ha and SII filters. The article includes, on page 73, an excellent image taken from "the suburbs of Boston, Massachusetts."
I was wondering if anyone locally had done any "urban imaging" using this technique and what they thought of the idea.
