BAADER 2" L-RGB CCD 111 Filters set - PRICE REDUCED
FOR SALE
My little used Baader 2” CCD L-RGB filters set in near new condition
$500 posted
The filters (in case of a filter set: each individual filter) comes in a Baader Filterbox, stackable on all sides
Baader has partnered with the world's leading thin film coating company to produce transmission curves that border on the ideal.
The Baader Blue filter passes virtually all of the H-Beta and O-III lines, while the Green filter is able to capture all of the O-III line, without encroaching into the H-Beta line.
In addition, the Green and Red filter passbands nearly touch, leaving only a sharp notch to block out the primary Mercury/Sodium light pollution line at 580nm. The high transmission everywhere else delivers the shortest combined exposures possible.
Please PM for purchase and postal details
