Thanks for the reply and helpful suggestion; I should have thought about stating my location in my original post so folks like you and others didn't have to look at my profile and do some sleuthing to figure it out. I'm in central Pennsylvania (USA). Also, I realize the Canon 60D I am interesting in modifying is an older model DSLR with a limited sensor size and resolution, but the one I have is in mint condition.

I am looking to have my Canon 60D modified for astrophotography with the h-alpha conversion sensitivity boost using both lenses and telescopes. The most important facts: I want my camera to preserve focus to infinity with lenses after the modification for widefield Milky Way astrophotography A conversion with just h-alpha and sulfur II sensitivity increase but blocking infrared light to avoid out of focus halos around stars The Best companies offering this Astro Conversion service for a clean modification with even focus across the image I really appreciate your answers regarding this matter. Clear Skies Benjamin
