Album: Deep Sky & Wide Field

The Leo triplet area, done with

- Camera: Pentax Kp APS-C DSLR
- "Telescope": SMC Pentax-D FA 100mm F2.8 Macro WR (at full aperture, so effectively a 35mm telescope)
- Mount: Tripod w/ Vixen POLARIE tracker
- Date: 2023:03:22, 01:13:18 to 02:05:55
- Sky: Bortle 1, clear condition, Moon down
- Frames: 288*9.06 sec @ 1600ISO, in-cam processing suppressed as much as possible (about 85% used, rest discarded due to windshake affecting PSF)
- Processing: Siril (1.0.2, because it still has a DSLR-raw converter module), no calibration frames!, just register, stack, bg removal, some color balancing and noise reduction.
- Crop & few final adjustements w/ gimp.
