2" PRO UHC Filter

Omegon Pro UHC filter, for greater contrast in nebula observations
Sometimes we encounter celestial objects that we can't see clearly. They appear faintly in the eyepiece, halfway between the visible and the invisible. That's where the UHC filter comes in. With it, you'll see nebulae sharp and clear instantly. Magic? No, just technology.

Summary of the benefits:

• Universal: suitable for most nebulae
• Ideal for beginners in observation with filters
• For telescopes from 100 mm: increases contrast without darkening too much

The universal filter for your telescope
The UHC can be adjusted for visual exploration of emission nebulae, planetary nebulae, and supernova remnants, making it the perfect filter for deep-sky observers who don't yet have a filter. It's amazing how much detail suddenly emerges, not just with faint objects but also with brighter ones.
For example, the Orion Nebula is larger than you imagine, and with the UHC filter, you can discover even more clusters and structures. You could spend hours and hours observing it until you see it all...

Especially recommended for:

• Rosette Nebula NGC2237
• Eskimo Nebula NGC2392
• Lagoon Nebula M8
• Eagle Nebula M16
• Dumbbell Nebula M27
• North America Nebula NGC7000 and many more...

How does the filter achieve such a high contrast?

Or, in other words, why don't you need to travel to the Atacama Desert?
Interference filters like this one owe their excellent results to the fact that they block most wavelengths and only allow a few to pass through. Thus, the artificial lighting of urban centers is canceled out, while the light reflected by nebulae is free to pass through. Stars appear dimmer, and nebulae appear much sharper.

The Omegon UHC filter specifically allows the green light wavelengths (496 and 401 nm) to pass through, also known as OIII lines.

What telescopes is it suitable for?
The Omegon Pro UHC filter is essential for nebula observation. It can increase the contrast of almost any nebula. It's also compatible with small telescopes with apertures starting at 100mm, as it doesn't darken the image too much.
