Indigo Filter Wheel offers a range of cutting-edge features to enhance your astrophotography and astronomical observations.
This compact and efficient device boasts seamless filter switching, ensuring precise and effortless transitions between filters for minimal image disruption. With its robust build quality and compatibility with 7 position 2inch mounted or 50mm unmounted filters, the Indigo Filter Wheel provides versatility and convenience.
Its integrated stepper motor technology and optical encoders allows for precise filter positioning, and it’s designed to work seamlessly with popular astrophotography software for remote operation.
Both sides of the filter wheel have M54 openings. The screw slide adapter allows you to properly align the orientation of your camera or telescope side. Just untie the screws and rotate the adapter to the desired orientation.
The carousel has seven (7) slots and accepts 2-inch mounted or 50mm unmounted filters. (Max filter diameter should be 50.8mm)
Filter Wheel rotates clock or counterclockwise direction for filter selection. A combination of a direct drive stepper motor and optical encoders ensures that your filter selection is precise, and deadly accurate on every filter location.
The wheel employs a shortest-path algorithm, ensuring the most efficient and optimal filter changes with minimal movement.
The body of the Indigo filter wheel is aluminum CNC milled. High-quality aluminum alloy allowed to design the filter wheel as thin as possible.
(19.0mm, 19.6mm with adapters installed on both sides).
Camera connection: The camera side allows direct connection with astronomical cameras that follow:
- 6 x hole pattern (62mm diameter pattern) – can accept M3 or M2.5 screws.
- 4 x hole pattern for PlayerOne cameras.
- M42 male / 0.75mm pitch.
LRGB filter set - for astrophotography using monochrome CCD cameras
Four filters for a colour image - The LRGB filter set is used to photograph the sky in colour using a monochrome chip camera. Monochrome CCD cameras used for astrophotography provide a bright image of deep sky objects at very high resolution as all the pixels on the chip work together to produce the image. However, the resolution is minimized with cameras using colour CCD chips, as about ⅓ of the pixels have colour filters.
Only an LRGB filter set with a monochrome camera makes use of the entire chip and can hence generate a high-resolution colour image.
L - the luminance filter
The luminance filter passes the entire visible light spectrum but blocks near UV and IR light - so this filter collects all the useful object information.
RGB - each filter has a special task
These three letters stand for the three different RGB colour filters from which you finally create your colour photograph. The colours that we perceive consist of the three primary colours - red, green and blue. Combined, these give all the colours that we can see. Our eyes too mix all the colours of our world from internal RGB receptors (or filters).
The four images from LRGB channels are combined in the image processing procedure and basically create the final colour photograph.
Tip: Using the Omegon Filter Wheel with the LRGB filter set for your astrophotography lets you change filters in just seconds.
The advantages in a nutshell:
- LRGB filter set for colour photography with CCD monochrome cameras
- full chip resolution via four different external filters
- durable - scratch-resistant coating
- neutral colours for deep sky objects and planets
