Description

After an hour of collimating the 9.25 SCT using Vega (thru my slit of sky between counter-arching trees in the backyard)...the scope took 100 30s subs of the Trifid without a filter, the first time I've ever foregone even a UV/IR cut filter. The result was surprising after the data was stretched - and I've regretted not trying this sooner, now. I had always assumed Dallas, Texas - and Bortle 9 - would be a waste of time without light pollution filters. M20 seemed to prove that wrong.
