Another reference image with the SW120 Esprit.. I really need to go back to PSD to mix in Ha with galaxies. My attempt to do so in PI is lacking. This was again at the native F/7.2 from a pretty bright suburban location. Almost can get into the faint clouds.. Thinking that next year the 6120 camera will make that a bit easier. Of course heading to a good dark location make sense too. Hard to leave the comforts of home.
