That's good news that it works well with a fast telescope such as the RASA 8; I was a bit hesitant to jump on it, as I wasn't sure how well it would have worked with the hyperstar.
Good vid! I live under a Bortle 8 sky and for a while, I had been using this Quad filter as a dual NB solution for shooting nebulas, while resorting to the L-pro for shooting galaxies. However, I recently turned the Quad onto galaxy imaging, just to see, and realized -as you pointed out- that it works even more nicely than the L-pro! I have now decided to use the Quad on all galaxies and, depending on the seeing and Mag, I will either continue to use the Quad on certain nebulas or the L-enhance or the L-extreme for others.
I purchased this filter about 10 months ago after watching.a review in the Dark Rangers youTube channel. I use a C8 (non HD) and ASI071MC Pro OSC with OAG and I've only been imaging for about a year. I noticed when I purchased it from AstroAgena a warning on the description page that halos were not a defect on the filter and a return wouldn't be allowed. I purchased anyway. Bright stars do have halos but yours seemed better than my C8 but I'm shooting at 1400 mm and bright stars will show a pronounced a halo because they show up bigger. I notice when using a bright star to check focus at lower exposures the halo diminishes. Even without the filter bright stars have some halo on my C8. When I say bright star it's a major star like Alnitak or the bright star in the Western Veil nebula or one of the major stars of Cassiopeia near the Ghost of Cassiopeia. Most of the time for galaxies and nebulas like Pac Man, Dumbell, Iris, Elephant Trunk the filter brings works well. But I also have read that other manufacturers filters will have halos around bright stars. I have no experience using other manufacturers light pollution filters. I'm now in a Bortle 7 area and I'm shooting the Wizard Nebula and I'll be able to compare these new frames from a Bortle 4 area a week or two ago. Thanks
Thanks for sharing! Antlia has this warning on all of their filters are I really like that. They are not overselling their products but are very transparent about what it can do and what not.
What color camera did you use? Did it have an AR window or an UV/IR cut window? That quad band filter becomes a tri-band filter if your camera has an UV/IR cut window since the 4th band 760nm - 800nm is blocked.
From a light pollution filter point of view, there is nothing better. It will not make your pics perfect, but it will make the light pollution manageable. What I would recommend for you is definitely to go as narrow as you can when you shoot narrowband. There is a new Antlia ALP-T 3nm filter out there - I would very much recommend that one.
A great review Sascha! I would be interested to see how this filter performs under a full moon? I currently use a very mild light pollution filter, the Baader Neodymium, but anything more than a half moon and I don't do any imaging. I'm in a bortle 4 area.
I’ve been using the Baader Neodimium too under my Bortle 6-8 skies (my city of 130,000 people is given as Bortle 8 in the Dark Sky maps,but a fine grained one give my house’s location as 6). After seeing Sascha’s review, though, I think I will look into this filter.
I won this filter in the optolong contest and I have to say it mirrors your examples, perfect for where I live in bortle 6 skies when there is no moon.
@@viewintospace The ASI2600MC Air comes with a IR cut coating for this OSC camera. The 4th near IR band is filtered out so this filter is only a tri band with this camera.
Best Sascha All the information you always bring is very instructive, but there is something wrong with the images, the background is perfectly sharp, but your own image is not sharp.
Yep, will have to look into that. Given that it's green screen the background is a pic, so no wonder it is sharp, but looks my cam has issues focussing..... Thanks for making me aware
Great review Sascha!👍 That's my default filter now too. Really liked its perfomance on the RASA 8 from my light polluted city

That’s really great to hear - thanks for sharing your experience!
I used this filter on my Crescent Nebula and it did a super job. It is my go-to filter.
Just used this on M45 too, but with much trepidation. I was not sure about the band pass for a reflection nebula but the result was very pleasing!
This matches my experiences. Always an improvement over IR/UV in Bortle 4/5

So the ASI533 would be a good match for this filter. I'm wondering about star bloat. Any idea if that's a concern?
Not really - I did measure in one comparison the PSF has it is practically the same
I have the ASI2600MC Air, so yes, that part is blocked
Hi, I'm under a Bortle 9 sky, Would you still recommend this filter for me? If not, which filter do you think I should use? Great video, Thank you.

@@viewintospace Thank you so much.
Good video thanks, what was the target with the star in the middle and red nebula?
That was the Butterfy nebula in the Sadr region
I recently compared this filter with the Optolong Quad-L enhance and I think this one is marginally better...
Thanks - great to know!
@@viewintospace I think it does a better job of colour "passthru" ... than the Optolong... just fyi I can also recommend their tri-band also!

It would be interesting to see how it does with the PINWHEEL galaxy, in my bortle 9? M45's nebulosity eludes me in this LP😢
Should've done a comparison between the L-Pro and the quadband also.
Yep, would have been great! But I sold the L-Pro some time ago....

@nikaxstrophotography you won Antlia filter on Optolong contest??
@@FirstofHisName-c1h optolong quad band very similar to the antlia
(3rd place)
@@nikaxstrophotography Wow! Congrats! Yes, these filters are somewhat similar, but different nonetheless.
What camera were you using? On their website it says to use a camera without a uv/ir cut built in for this filter. Just wondering about star bloat.
I used the ASI2600MC Air.
@@viewintospace The ASI2600MC Air comes with a IR cut coating for this OSC camera. The 4th near IR band is filtered out so this filter is only a tri band with this camera.
I think someone stole your furniture
No money for furniture - all spent on telescopes 😉
How about a broadband target comparison with quad and without quad?
Andromeda is a broadband target….
