9:30 a.m. — Using PixInsight in photo processing


Pixinsight has a reputation for being complicated, but you don’t have to master hundreds of pages of technical mumbo jumbo to use it to process your first astrophoto.  In this talk, Kevin will demonstrate everything you need to know to turn your raw images into a finished picture.  First we’ll walk through each of the basic steps:  calibration, stacking, and stretching.  We’ll use the remaining time to discuss some more advanced techniques like noise reduction, sharpening and masks.  This is intended to be a hands-on practical demonstration rather than a lecture.  We’ll post the data Kevin will be working on in advance so you can download it.  Bring your laptop and follow along as we process the image together.  And if you have any data of your own that you want help processing, be sure to bring that as well.


Kevin got sucked into digital astrophotography when he held his 5-year old’s Barbie camera (0.02 megapixels!) up to his C8, and it’s been a long road from there.  After hurricanes and chainsaws devoured all of his neighbor’s trees, he built an observatory in his back yard.  He warns everyone that he doesn’t really know what he’s doing, yet he still gets some very pretty pictures.  And what one fool can do, another can.

Kevin is also the organizer of NOVAC’s astrophoto processing SIG, which meets every few months at Fairfac County’s Providence Rec Center. Meetings are announced on the NOVAC web site.
