Last night presented some imaging opportunities through somewhat hazy skies, I set up the F/4 newt and the DS 2.3+ (with UHC filter) and set to work. I decided to capture my darks with a 30-second integration at gain 30. This combination offered a general dark set that could be used for most of the imaging session, offering also good control of amp glow that can appear in stacked images with histogram stretches.
Here is a full-frame image of M1. The integration time was 30 seconds, and this is a stack of 12 exposures (the best of the 20 or so I captured). Detail on the image is quite good and the skyglow and amp glow are well controlled. All in all, I'm pretty happy with this pic, which gives a good idea of the capabilities of the Newt/DS 2.3+ combination.
