Fantastic Full Color — Apertura 1.25″ UV/IR Astrophotography Filter
Protect your images from ultraviolet and infrared light with this dedicated
astrophotography filter from Apertura! This quality imaging option is designed
to offer high transmission of the visible light while cutting out the extreme
ends of the spectrum. If you’re looking to enhance your full-color imaging
experience, then the Apertura 1.25″ UV/IR Astrophotography Filter is sure to
give you a boost!
Full-spectrum imaging provides an excellent perspective on broadband targets
and engaging takes on even a variety of narrowband targets! When you want to
create these powerful images it may seem a completely unfiltered view is the
way to go, however this is not the case. One Shot Color and monochrome sensors
alike see much more of the light spectrum than we can, and this is
where the Apertura 1.25″ UV/IR Astrophotography Filter comes in. As the target
of telescope optics is focusing the light we can see, the imperceptible UV and
IR light is often less sharp (particularly with refractors). By blocking these
softer wavelengths from your sensitive camera sensor you can see an increase
in star and image sharpness, making your stellar full-color images even more
stunning! With a precision off-band coating and Schott B270 substrate,
Apertura has ensured your imaging system precisely cuts out the UV and IR
spectrum while providing an average max transmission of 98% of the light you’re
interested in – including the all important H-alpha band!
Ultraviolet and Infrared Filtering: A Closer Look
How can you tell if a filter’s filtering profile will work for your needs?
What should you be looking at when comparing one filter’s specifications to
another? It’s all in the chart! A filter’s transmission chart gives you an
in-depth at what wavelengths of light it is allowing through as well as how
much of the total information on that wavelength is actually reaching your
imaging sensor. While these graphs may seem a bit of an enigma at first, once
you learn what to look for, interpreting is easy! We’ve put together a helpful
guide that will quickly train your eye for these helpful graphs and have you
reading and comparing filter charts in no time. You can find
How to Read a Filter Transmission Chart and Choose a Filter

Precision Filtering, Premium Construction, and Broadly Compatible
The Apertura 1.25″ UV/IR Astrophotography Filter offers high-quality filtering
performance and construction in a form factor that will fit just about any
1.25″ filter solution on the market!
Superb Full Color Photos
Full color imaging is a
great approach for capturing a wide variety of targets, from broader band
objects like galaxies, planets, and stars, to more narrowband targets alike.
Whether you’re creating these images with a one shot color (OSC) camera or a
monochrome camera using RGB filters, leaving the UV and IR spectrums
unattenuated can impact the quality of your images. That’s where this filter
comes in! By blocking these problematic wavelengths while maintaining a very
high transmittance in the visible spectrum, the Apertura 1.25″ UV/IR
Astrophotography Filter ensures you get a performance boost with virtually
no impact on the signal you actually want!
Wide Compatibility
This filter is perfect for smaller
sensor cameras, and can be used with some excellent accessories designed
for those imaging systems! For monochrome imagers, this can be used as a
luminance filter in conjunction with RGB filters in an automated system like
the
ZWO EFW 8-position Filter Wheel for 1.25″ and 31 mm Filters . If one shot color imaging is more your style, then this can be used with
the popular
ZWO Gen 2 M42 x 0.75 Filter Drawer for 2″ Filters
in conjunction with the
ZWO 2″ to 1.25″ Filter Adapter Ring for Filter Wheels and Drawers , or other excellent options like the
Askar M54 Filter Drawer
and the
Apertura Camera Adapter System. Please note all accessories listed are sold separately.
High Quality Construction
This filter features high
quality components from the base to the coating! The core of the Apertura
1.25″ UV/IR Astrophotography Filter is a 1.85 mm thick Schott B270 substrate which is
known for its excellent transparency. This helps ensure that the
high-quality coating is the only thing getting in the way of the incoming
signal! Speaking of coatings, this accessory’s filtering layer is bonded
using an Ion Assisted Deposition process. This IAD technology gives the
coating enhanced durability to help keep this quality filter in your imaging
tool kit for years to come! This coating is designed with precision off-band
blocking, providing your imaging system with the exact filtering profile
you’re looking for. Couple all this with a λ/4 and 60/40 surface
flatness and quality respectively, and you’ve got an excellent upgrade for
your astrophotography setup! This is mounted in a 5 mm tall filter cell featuring and is
threaded for common 1.25″ filter cells, drawers, and wheels.
