The Wizard: Unveiling Nebulous Wonders with the L-Enhance Filter
Sometimes, a celestial target just clicks. For me, the opportunity to image the "Wizard" nebula presented itself with a chance to put a new piece of gear through its paces – the L-Enhance filter. And let me tell you, once you see it, you can’t unsee it.
Navigating Suburban Skies
This particular imaging session took place under Bortle 6/7 suburban skies. A familiar challenge for many budding astrophotographers, these light-polluted conditions can often wash out the delicate details of nebulae. However, the L-Enhance filter proved its worth. The typical "grey" sky background, which often requires extensive stretching in post-processing, was significantly reduced. This meant more of the faint nebulosity and stellar detail could be brought forth without fighting the pervasive light pollution.
The Guiding Challenge
While the filter excelled at enhancing the nebula’s signal, it did present a slight hurdle: locating a suitable guide star. To acquire a stable guiding lock, I had to increase the exposure interval times to 3 seconds. Surprisingly, this didn't negatively impact the guiding performance. My RMS guiding error consistently stayed within a respectable 0.32 - 0.56 arc seconds, which is excellent for maintaining sharp stars during long exposures.
Battling the Dew
As the night progressed towards 5 AM, the dreaded dew began to settle. Despite my initial concerns that dew might become an issue, I was relieved to find that not a single sub-exposure was lost due to it. This is a testament to either good fortune or perhaps the subtle benefits of the filter housing itself, though further testing would be needed to confirm.
Imaging Details:

- Telescope: Celestron Edge 8 w/ 0.7 Reducer (f/7)
- Camera: ASI2600 Air
- Guiding: Onboard guiding
- Mount: EQ6R Pro
The Final Image
Here's the culmination of the night's work, showcasing the stunning details of "The Wizard" nebula, made possible with the aid of the L-Enhance filter:
This experiment has certainly solidified the L-Enhance filter as a valuable tool for imaging under less-than-ideal skies. The ability to cut through light pollution while revealing such intricate details is truly a game-changer.
