Does the filter work with galaxies and clusters?. I have a 80mm refractor. Will it block too much the light of the objects?

I have a DSLR, Canon 600D which is full spectrum modified. When I take astronomy images I get "bleeding stars" even with this UHC-S 2" filter. I use your UFC which is just perfect.
I take images with both 8" SCT and widefield 210 mm APO lens and in both setups I get this effect. It seems that I get too much of the red wavelengths.
What kind of filter solution do you recommend for astroimaging with a DSLR full spectrum modification?

1¼" and 2" Baader UHC-S DeepSky Filter

Planeoptically Polished

Baader UHC-S DeepSky - All Filters
All Baader UHC-S DeepSky Filter
1¼", 2", 50.4 mm, 50x50 mm

Planeoptically polished for the highest images quality. Produces a much brighter image with superb contrast than a conventional Nebula filter. Excellent for openings from 100mm.

Baader UHC-S Nebula Filter with highest transmission and realistic star colours!

A new class of LPR Nebula filters finally delivering the happy medium, with enough light for smaller telescope openings at the same time with the high contrast of classical UHC filter.

Light pollution from street lights is blocked carefully. The filter is the sensible addition to all previous deep sky and UHC filters. Both for visual as well as photographic use.

All filters produce a brighter image and are optically polished with ultra-hard dielectric coatings. They are absolutely scratch resistant and can be cleaned as often as needed, ideally with Baader Optical Wonder Cleaning Fluid.

Alternative zu den extrem teuren Filtern anderer Hersteller
Eigentlich war nur ein UV/IR Sperrfilter geplant. Der UHC Filter bietet dies gleich mit. Man sieht einen Kontrastgewinn bzw. der Hintergrund wirkt bei gleicher Belichtungszeit nicht mehr so rot bzw. grün. Vermutlich schluck er auch feine Details, aber bei meinem Lichtsumpf spielt das eine untergeordnete Rolle.
Fazit: Zu dem Preis kann man nicht viel falsch machen.

UHC - Filter
Ich bin sehr zufrieden, der Filter erfüllt umfänglich meine Erwartungen.
Meine Balkonsternwarte wird durch störende Straßenbeleuchtungen und Licht aus Fenster der Nachbarn beeinflusst. Außerdem ist der ganze Himmel im Wohngebiert aufgehellt.

Der Filter eliminiert das störende Fremdlicht wie erwartet und erhöht deutlich die Qualität der Aufnahmen von Nebeln.

As good as expected
I purchased the 2'' version of this filter. It seems to work simply excellent together with my modded DSLR and a 1000 mm Newtonian, together with a coma corrector. Pacman Nebula, stacked in APP. I'm very satisfied.
  • Quality, final images.
  • Difficult to find any?

I can at last do long exposure with less city light polution.
  • Packaging and the plastic box

Gewohnte Qualität
Wie auch bei meinen bisher von Baader Planetarium gekauften Filtern ist auch das L-Booster Filter von sehr hoher Qualität. Im Vergleich zu anderen Filtern dieser Art ist das "Farbverhalten" an meinen ZWO ASI OSC-Kameras neutraler und ausgeglichener. Signifikant ist die sehr geringe Streulichtneigung an hellen Sternen, was es für mich zum bevorzugten L-Kanal-Filter macht. Mechnisch und fertigungstechnisch bewegt sich das Filter auf gewohnt hohem Baader-Niveau.
