Description

Acquired over different nights. 2 hrs with an old Leitz 135mm @ f/5.6 lens while at RTMC in Big Bear, CA and another 2 hrs with a Mamiya 645 150mm @ f/4 from Joshua Tree NP - Cottonwood Campground a couple months later. No calibration frames! All done on an iOptron SkyTracker doing 3 min subs and throwing away about 10-15% of the images due to bad tracking especially with the much heavier Mamiya lens.
