Excellent filter quality and useful for planetary imaging
I'm using the BAADER SLOAN r' and g' along with the Baader CMOS L filter with mono camera for planetary imaging luminance and mix them with Winjupos software. FOr colors, I just use the Baader CMOS L filter with another color camera and put the color on the luminance afterwards.
The SLOAN r' (= red + part of green) is the less sensitive to medium seeing and can help you catch some nice details especially on North & South pole of Jupiter for instance.
Using L CMOS filter requires good seeing.
And when the seeing is excellent, the SLOAN g' (blue + part of green) can give you the best resolution and make you compete with bigger apertures.
As Baader filters have the same thickness and as my Newtonian s perfecty corrected in blue (contrary to SC for instance because of spherochromatism) the focus point is not changing while I change from one filter to another. It makes things also a little easier.
I'm definitely happy with these filters!
