Hey Everyone! In the video, we mentioned this filter being tested under Bortle 2 skies. This was a mistake on our part, and Diana confirmed that the testing of the filter and the final image were, in fact, shot under Bortle 5/6 skies during a partial moon phase. That said - these tests were done to show how well the L-Para controls halos on bright stars. The final result in such conditions however is a huge bonus and attests to the quality of the filter itself.
Beautiful images. I especially like the way it handles bright stars with no halo effect! From a marketing perspective, getting results from Bortle class 2 skies only makes 95% of us envious and left wondering "Gee I wonder how it works in my Bortle class 7 to 8 skies?". Just saying......
Thanks for the intro on the filter. However, why test it under Bortle 2 skies if it's aim is for urban settings? The bautiful data collected could easily be achievable without any filter in B2 skies. Am I missing something?
It has a wider band pass than the L-Extreme but narrower than the L-Enhance. So how is the L-Para better than either? Because of its better halo suppression? The other Optolong’s were pretty bad for OIII haloes. This one looks much better. Thanks for the introduction.
How does this filter directly compare to the L-Ultimate which I have now, would it be an upgrade to switch to the L-Para? Which of the two has the better ability to reduce halos around bright stars?
The L-Ultimate has an extremely narrow bandpass of 3nm, compared to the L-Para which is less narrow at 10nm. However, the ultra narrow bandpass of the L-Ultimate will only work well on telescopes with a focal ratio of f/4 or slower. The L-Para is more versatile and can be used with the fastest telescopes at f/2 and any slower telescopes as well. Both filters perform well in preventing harsh halos on bright stars!
Great question! The L-Para should be used with a color camera, so you'll get data in full color. This is because the L-Para is meant to enhance the natural colors of the nebula.

Bortle 2 not a great test for blocking light pollution. Rather see results from a bortle 7 to see quality of filter

For city environments... but, you tested in Bortle 2s...🤔
Arizona border 2 skies.You're pictures would come out magnificent with no filter
Awesome review!
How much. ???

Is there an attachment that will add color to nebulae on a telescope?
Great question! The L-Para should be used with a color camera, so you'll get data in full color. This is because the L-Para is meant to enhance the natural colors of the nebula.
@@highpointscientific Thanks!
What camera did Diana use for these images?
Great question! She used the ZWO ASI2600mc Air Smart Camera.
Which bortle zone was this filter used in ?
He says Bortle 2, so imo its not an accurate review. I need to know how it performs above bortle 6, 7...
Great filter! Will you all ever do a long term review of the Skywatcher CQ350?
nice
I don’t get the reasoning with testing this in bortle 2. You’d get fantastic results with just a uv/ir cut filter in these conditions
Yayy I got Celestron space telescope in christmas! Do that Optolong L-Para 2 Dual band filter works on Celestron telescopes too? If it works i'm in! 😊
Yes, the L-Para will work with Celestron telescopes! It's a standard 2" mounted filter.
@highpointscientific yayy thanks!
