"Narrowband Imaging Considerations..." on Oct. 15th

[Richard Bell]

The Kalamazoo Astronomical Society, the oldest and largest astronomy club in Michigan, invites you to attend its next Astrophotography SIG meeting on Friday, October 15th at 8:00 pm EDT. This gathering will be held on Zoom and is free to attend.  Here's a preview of the feature presentation:

Narrowband Imaging Considerations & Lessons Learned from Southern Michigan
presented by Jonathan Young

During this talk Jonathan will share several examples of the lessons learned from his narrowband-imaging and processing experience. First, an example of how to balance sensor and equipment limitations using a few test images in order to maximize practical SNR. Then, strategies to improve acquisition efficiency and image quality under changing local sky conditions including examples on managing the impact of smoke, moon, low altitude haze, and light pollution gradients. Next, how to determine practical calibration limits including the power of dithering. Then a quick tutorial using Siril including a powerful tool for gradient correction prior to stacking. Result comparisons of several stretching techniques such as boosted tone mapping, Ha-SHO combinations and weighted luminescence using Startools. Examples of color balancing results including Hubble pallet, artistic weightings and CEILab. Finally, the importance of proper monitor calibration and adjustments needed for different publication mediums including online, metal, canvass and acrylic.
