Indigo Filter Wheel
Our new high quality Indigo Filter Wheel has a 7 position carousel and can house 2inch mounted or 50mm unmounted filters.
One cable operation
Filter Wheel requires a USB2 (TypeB) cable only. This simplifies the connectivity as it does not require a separate power supply when used with USB control.
Accurate Filter Selection
Carousel has seven (7) slots and accepts 2-inch mounted or 50mm unmounted filters.
We strongly suggest our photographic 2-inch filters (included) in combination with the Indigo Filter Wheel.
Filter Wheel rotates clock or counter clockwise direction for filter selection. A combination of a direct drive stepper motor and optical encoders ensure that your filter selection is precise, dead accurate on every filter location.
Thin Design
The body of the Indigo filter wheel is aluminium CNC milled. High quality aluminium alloy allowed us to design the filter wheel as thin as possible (19.0mm, 19.6mm with adapters installed on both sides).
Orientation on both adapters
Both sides of the filter wheel have M54 openings. The screw slide adapter (image below) allows you to properly allign the orientation of your camera or telescope side. Just untie the screws and rotate the adapter to the desired orientation.
Camera Connection
The 6 screw holes on the camera side allows direct connection with astronomical cameras that follow the same 6 x hole pattern (62mm diameter pattern). A neat feature allowing you to reduce the total backfocus instead of placing adapters.
Mechanical Design
LRGB Filter Set
We are glad to announce the availability of 2 inch mounted deep space photographic filters for broadband and narrowband usage.
Parfocal LRGB Filters
Broadband filters are parfocal which ensures that you will not have to refocus when you quickly switch filters to capture images.
Anti-Reflection Coatings
Multi-layers anti-reflection coating ensure no halos, ghosting or reflections. Filters are resistant to scratches and do not get affected by temperature change.
Equal weight on RGB filters
RGB color combine weights are 1:1:1
Limit Sodium Light Polution
A gap between green and red filters blocks out the primary Sodium light pollution line at 589nm and improves color balance and separation.
Max transmission
Filters have been designed to allow max transmission for true original, natural color imaging.
Luminance (UV/IR Cut)
The Luminance UV/IR Cut filter is designed for ultraviolet and infrared wavelength blocking to improve sharpness of the image and reduce halos on lens optical systems.
It can be used on a CMOS and CCD cameras which do not have an IR protection filter toward an image sensor or were remodeled (DSLR, Mirrorless).
This type is required to unfiltered CCD and CMOS sensors as they are extremely susceptible to UV and IR rays just outside the visible spectrum can have a very negative impact on image quality.
