I'm curious why you are jumping into this discussion from the perspective of "I won't look at the information you are offering, and instead will rely exclusively on my own experience to claim that you are wrong"? If you haven't experience it, that's awesome, I'm genuinely happy for you. However others have had problems, and we are sharing our experiences, and even evidence of the problems (the above image I shared is from the L-Pro and this comparison I did a while back is the L-eXtreme) so coming in here to claim we must be making it up or seeing phantoms isn't particularly helpful.

The OP is about IDAS D3 vs. Optolong L-Pro not about complaining about halos with the L-eXtreme or whatever. Besides, there is no offering here but a guy making money out of his YT channel and as far as I'm concerned unless is written it doesn't exist. I'm sorry the Optolongs didn't work for you but it did for me so I'm feeling entitled to share this side too and also suggest that the law of the averages applies.

I shared an image of a halo produced with the L-Pro, which is why I switched to the LPS-D3, which is why that is relevant, and the conversation expanded into the issue of halos being a recurring theme across the Optolong product line. None of that has anything to do with YouTube, but the YT video was another data point. And what does being written have at all to do with veracity and accuracy? Like I said, I'm glad it work for you, and I'm glad you shared that. My issue is with your implication that *because it worked for you* all other opinions and experiences are invalid.

Weird all these people complaining about the L-Extreme causing these "terrible" halos (what are they and what would be a "terrible" halo look like, btw?) with me not seening any in the 2 f/4 system I have. Again, go figure...
There’s a guy on YouTube who’s done videos testing multiple of the same model optolong filters with a calibrated spectrometer & has illustrated how inconsistent their quality is with the same filter. The L-extreme is one he’s focused on particularly. You might have just lucked out & got a one from a good batch. Mine is not one of those & I think my experience is kind of typical.
That's Cuiv the lazy geek. This is his most recent video on the topic, from only 12-days ago.
I spectro-analyzed my SUBSCRIBER'S FILTER... and it wasn't good  - YouTube
I own the L-Pro, the L-eNhance, and the L-eXtreme, all purchased based on recommendations from various Astrophotography "influencers". I've been fairly disappointed with all them. I've since replaced the L-Pro with an IDAS LPS-D3, and the L-eXtreme (which itself was a replacement the L-eNhance) with an IDAS NBZ in my EdgeHD, the IDAS USH NBZ in my RASA, and the Antlia ALP-T in my RedCat 51.
yes sir, that’s exactly who I was referring to & I have seen that video you linked & others cuiv has done analyzing filters.
I also got the L-Pro & L-Extreme filters based on stuff I’d seen from multiple “influencers” on their channels in the past, like you. I think there are a number of those “influencers”, whom I won’t name specifically but you probably know who I’m referring to when I describe quite a few as more salespeople on their channels at this stage than they are really about accurate content. Cuiv definitely isn’t one of those, I’m referring to others who I think do not give totally honest reviews of gear & filters they’re sent to evaluate by various manufacturers & vendors, because said “influencers” are more interest in getting their small residuals from it & want to keep getting sent more free stuff to get to use personally for a while. There’s one guy in particular who has turned into little more than a sales guy who’s real content hasn’t evolved at all in years. Seems his only goal at all is just to pile up new subscribers so he can sell ads. I quit watching that particular channel some time ago.
the Antila ALP-T duo narrowband 5nm filter is what I just got to replace my L-Extreme. Curious why you’re only using it with the small redcat & not also with your SCT?
I have a somewhat similar combo of scopes, a 610mm F4 Newtonian & an 8” edgeHD SCT & do plan to use that filter with both. I did that with the L-Extreme also & never had any issues at all platesolving through it with my SCT.

Cuiv is a solid contributor to the community, he even authored some of the early code in NINA. I trust his content because he's given me no reason not to.
So, the reason I have the Antila on my RedCat and not on my EdgeHD is because I put a filter wheel on my EdgeHD so that I could easily, and remotely, swap between clear for planets, broadband for galaxies, and dual narrowband for nebula. And now that it's dialed-in, I dread tearing it apart to put the Antlia in there ;-) So I'm debating if I give Optolong one more try with the L-Ultimate, or buy a second Antlia for EdgeHD so that when I do eventually tear it down to open up the filter wheel I only have to do it once. I should mention my setup is on a permanent pier in a SkyShed POD, so I'm optimized for never having to touch it.

I live in a Bortle 5 zone. I recently acquired data on M33 with a dual setup. 6hrs with a Skywatcher Esprit 100 / ASI183MC and 6hrs a ponybacked AT65EDQ / ASI183MC. I used an L-Pro with one setup and a standard UV/IR filter on the other. Can you tell me which one was the L-Pro?
I'm convinced that there is no visible benefit using a LP filter, in my zone at least.
Both of these are unprocessed....registered, linear fit, DBE, and STF stretch.

There definitely is a benefit, I’m in Bortle 5 as well and I won’t image without a filter anymore. Looking at your images I’d guess the one on the right, with the SW100, was with the L-Pro. There is less flaring around the brightest stars making them appear less bloated.

You're perfectly right. I'm ditching using the L-Pro on anything above 70 deg of altitude even in my Bortle 6-7 skies. There is no real benefit except for a somewhat darker background if the skies are dark enough. Broadband targets, obviously.

Hi Jason,
The one with the L-Pro is actually the AT65EDQ/183MC, the one on the left. The AT65EDQ has somewhat of a signature in how it renders stars, and that's why it looks a little bloated on that stretch.

Nice setup. Sounds like we have been on a similar journey, though I’m not yet in a position to build a permanent observatory. Couldn’t really do it from my house, though there is room for one, because I’m in bortle 7, bordering on bortle 8 within the city limits of Charlotte, NC. Any observatory for me would have to be somewhere else that I could remote into from home. That changed the thought process.

U need idas P3, not the D3.
It woul be correct L-Pro vs IDAS P3, not L-Pro vs IDAS D3.
D3 is suitable for observe.

Never mind, looked it up myself. The P3 is only available for Canon EOS DSLR and mirrorless cameras. The D3 has those versions as well in addition to the 2” (M48) mounted version for telescopes. So for what we are talking about here the P3 is not an option.

If you are looking for a 2” filter for astrophotography, then the correct version from IDAS is the IDAS LPS-D3. That is the part. Not a P3.

That one was what I've bought, and I'm very happy with it for astrophotography. Unhappily weather hadn't let me do many astrophotography sessions, but you can see some results published in Astrobin in my profile. For example: NGC7000 and Andromeda Galaxy.

From the link it says the P3 is no longer available, but the transmission curve chart shown is exactly identical to the LPS-D3, so I think the P3 may be an old part number for the same thing.

IDAS, Astronomik etc seem to have better coatings / less halos than the Optolong. It works ok on my f/7.8 refractor but not well at all with fast optics. Hyperstar = v bad halos on bright stars with the Optolong. I have a L-Pro for sale if anyone wants it

I have the IDAS-LPS-P3 similar to the D3 with an unfiltered Nikon Z7. And I find that it looks very good with a nice color balance and no artefact on the stars.

I have 1 L-Pro, 2 L-eNhance and 1 L-Extreme and none of them produces those halos. I cannot suffer YT reviews so I'll pass it but from the few frames it seems complaining about the bandpass shift which might or might not an issue (and certainly isn't for both L-Pro and L-Enhance since they have a very wide bandpass). So either I'm lucky 4 times over or is it that I'm average and you the unlucky ones? With a proper statistic nothing can be said with any certainity, is it not?
Ciao Andrea. My experience is excellent with an L-eNhance (clip version on a modified Canon DSLR).
Conversely I have to confirm that the L-eXtreme that I used a lot with an ASI 2600MC-Pro, produces huge halos around the biggest stars. I resolved now to buy an ALP-T, but I do not have yet used it, therefore I cannot make a comparison yet.

she is the first person I’ve heard of who has not experienced the bad halos with the L-Extreme. I had that issue with mine & ultimately switched to the antlia variant.

Apparently not the only one. Maybe there is an issue with early releases? Also the type of optics used plays a signficant role in producing halos, with or without filters.
BTW, I am not a "she".

Sorry, no insult intended. Where I came from Andrea is normally a female name.
perhaps you just got lucky with a good batch of the L-extreme. Halos were/are an issue with those over a long period. Mine was not an early release. I have gotten the same halos through 3 different telescopes & using 2 different cameras. The effect has been consistent. Optolong has been known to be inconsistent with the quality of their coatings.
how old is your L-extreme filter? They may have finally fixed their issue.
