L-Ultimate Filter 2"A 3nm dual band designed to drastically reduce the effect of light pollution, the 3nm isolates the nebulae's emissions into H Alpha (red) and OIII (green blue). It blocks light pollution, maximizes the signal from nebulae, and darkens the sky background. It also blocks artificial light from mercury vapor lamps, high and low pressure sodium vapor lights, and unwanted natural light caused by the emission of neutral oxygen in our atmosphere. Maximizes
A 3nm dual band designed to drastically reduce the effect of light pollution, the 3nm isolates the nebulae's emissions into H-Alpha (red) and OIII (green-blue). It blocks light pollution, maximizes the signal from nebulae, and darkens the sky background. It also blocks artificial light from mercury vapor lamps, high and low pressure sodium vapor lights, and unwanted natural light caused by the emission of neutral oxygen in our atmosphere. Maximizes the transmission of the main emission lines of the nebula in OIII (496nm and 500nm) and H-alpha (656nm). Used with DSLR, colour/MONO CMOS and CCD, however, this filter is not suitable for fast ratio systems.The advantage of L-Ultimate is that it only passes through the emission lines OIII(500.7nm) and Ha(656.3nm), in which case all other light pollution emission lines are eliminated so that only the emission and reflection signals of the nebula are captured during imaging. Therefore, the sky background of the image is darker, and the contrast between the nebulae and the signal-to-noise ratio are improved to the greatest extent. In heavy light pollution areas, the product can also selectively filter light pollution and clutter signals through the emission lines of nebulae, and finally avoid the impact of light pollution on astrophotography.
It is different from the series of dual-narrowband L-eNhance and L-eXtreme in that L-Ultimate is a dual-3nm bandwidth filter that only passes through Ha and OIII emission lines. You will get a darker sky background, more contrast of the image and the suppression on stars. L-Ultimate has also been optimised in terms of halo performance, so that there is no obvious halo when shooting on a bright star object.

Easy To Use
These work great for a really good price. I love using these when I'm making dishes that would be difficult to clean otherwise.

Value, Durability, Everyday Use
What I liked:
- Price-to-value is the standout. These were significantly better priced than similar packs I’ve bought from local grocery stores and big discount retailers.
- For everyday, disposable use—think casseroles, baked pasta, brownies, roasted veggies—the lighter weight is perfectly fine.
- They stack neatly and are easy to store, which matters when you’re buying in bulk.
What I didn’t like:
- They’re a bit flimsier and not as thick as the store-brand pans I’ve used before. You can feel the difference when you handle them.
- For heavier dishes (large lasagnas, big roasts, or anything dense with sauces), a single pan can flex more than I’d like.
How I used them:
- Over the past couple of weeks, I’ve used these for baking brownies, roasting chicken thighs with vegetables, and prepping freezer meals. When I expected more weight or lots of liquid, I doubled up the pans, which solved the flex issue and kept everything stable.
- I also tested bending one to compare sturdiness. In the accompanying video, you’ll see me gently flexing the pan to show the “give.” In the photo, I placed this pan next to a thicker pan I bought at a regular store so you can see the difference in gauge.
My takeaway:
- If you need heavy-duty pans for very weighty dishes, these aren’t a perfect one-for-one replacement for thicker, premium options. However, for routine baking, storage, and serving—especially when you plan to toss the pan afterward—the cost savings make a lot of sense.
- Doubling them for heavier recipes is a simple workaround that maintains stability while still keeping the overall cost lower than buying thicker single-use pans.
Verdict:
- I’ll be purchasing these again for everyday use and bulk meal prep. The value is strong, and the performance is solid when you match the pan to the job or double up as needed.
