I'm getting ready to send my K5iis in for an astro conversion. First I'm not sure about which filter to get, full spectrum or visible + Ha. I know full spectrum is the most common but does it render the camera unusable for terrestrial use?
The second thing is the dust reduction system... It's it worth an extra $50 US the have it reinstalled after the conversion?
Finally, I was thinking of sending it to Spencer's but is there another service that I should consider, and why?
