48 x 120s a Baader LRGB Filter

An H-beta filter was also manufactured in the same high quality and technology as the new Baader CMOS-optimized (Ultra) Narrowband and Highspeed Filters. 
Now I was allowed to test the new 5.5nm narrow filter. Due to the slightly wider design, this filter is intended for aperture ratios from f/2 to f/10. 
And I can now report that this new filter also works perfectly at f / 1.9.

As a test object I chose the Sadr region, which also emits significantly in H-beta.
The H-beta data were mapped to a deeper blue relative to the OIII data. 

My hope is that this new H-Beta filter will enrich the SHO Hubble palette.

In the GIF animation I show the following sequence of data:

- S2HaO3Hb starless
- S2 starless
- Ha starless
- O3 starless
