2 more great shots Marc.. That setup is really showing some promise! How did you find the resulting colour balance after using the UHC-S? What are the benefits of using a UHC filter at a dark site? improved contrast between the nebulosity and the sky background? Does this at all interfere with the dimmer nebulosity or is that simply a matter of more exposure?
Does it in any way tighten stars up a bit like an NB filter would?
Sorry for the myriad of questions.. Just trying to figure it all out !
