    Never actually seen one of these scopes. Will be interesting to see what you think of it. 🤔

    So far, it's a bit terrifying haha. Managed to get the light pollution filter fitted yesterday. The original clear glass filter was jammed in solid :o

    But don't get me wrong Stace, it's still stunning images, and definately the best images I've seen with the AA triband filter! But spending money on a filter, you really want to find the one that matches what one is looking for

    Of course, you have to make sure you get it right first time. No point in spending money twice. 

    All I can say is I've imaged in a 53% moon and severe light pollution, I'm in bortle 6-8 depending on what direction I'm imaging. The AA triband (and I assume other triband filters would too) handled it very well. There was minimal moon glow/light pollution in my stack. In fact it was some of the easiest data I have ever processed. Coupled with the increase in productivity and efficiency , well with my osc I won't go back to seperate filters now.

  3. @Matzi a valid argument :) personally and this is my experience alone...I've had more fun and got better images since switching to the triband filter from two separate filters (a baader 7nm ha, 8.5nm oiii). It also depends on how you process the data. I've found the best results don't come from doing an integrated stack of all channels , but more like treating the data as though it is is from two narrowband filters. In astropixel this extract and extra stack doesn't take a lot of effort or time and yields great (in my opinion) results. 

    But yeah it all comes down to personal preference...but the not having to switch out filters, re focus etc has got me sold. It's so easy .

    Waiting to get my hands on a triband filter but need to wait until stock arrives!  Could anyone who has a bit more knowledge on these triband filters tell me if there is much difference in the specs between these two:

    Cheers!

    I haven't used the idas version, but I imagine they are very similar. The Altair offering is slightly cheaper at £215 for a 2 inch filter. It would have been nice for the band passes of the idas filter to be published on the product page too .

    I'm starting to wonder if I use my Baader 7nm Ha, and 8.5 nm OIII, if that will yield better results, than a duo/tri filter...

    Give it a go :) personally I've found better results with the triad filter :)

     

    this is a work in progress, but 10x240s (40 mins) on the eagle neb. Extracted the Ha and oiii data seperately using astropixel processor. I'd say these filters work really well :)

    Hi StaceStar!

    I did see your image here on the AA FB page just an hour ago, and I must admit it is the most promising image I've seen there yet! There were also one done with the quad filter, on the Cresent nebula, but that really didn't impress me. I don't know if it was due to some sort of problems, or bad processing. But I'd really like to know the nanometer values on each narrowband wavelengths (I know this probably don't matter much, it's the images the filters help produce in the end) But I always like to compare stuff on papers, and then the images they produce afterwards.

     

    I'm really looking forward to see your final results on your image with the triad filter! :)

    Hiya! Thank you for the kind words about my image, its still a work in progress but im very hopeful. A bit about where i image from, I live in Birmingham and my skies vary from bortle 6-8 depending on direction, I also have LED streetlights, the moon was up a bit last night and very bright....plus finally it didnt really get that dark at all last night. So in short i think this filter is brilliant.  I too saw the crescent image and i'm not entirely sure what has gone on there, but for me this filter has made quite the impact :)

    Hi Stacey, please could you post an unprocessed(unstretched too) single frame? Just to look at what the data looks like right out of the camera.

    hi! here are those files you asked for, all single 240s frames just converted to JPEG. 

    First is a single frame unstretched, second is a single frame with a medium stretch but background not neutralized, third is a single frame with the same stretch but the back ground neutralised. 

    None are dark corrected so thats why there is the typical 183 sensor glow on the right side.

    @StaceStar has recently acquired an Altair Astro triband filter but I cant for the life of me find a link?!?!

    Mine is a pre production one, they made about 10 of the quad and 10 of the tri...so sold out very quickly. However if you keep an eye on the site they will be making more soon :)

     

    Also incidentally got first light last night, this is only 14x 240s. (with 3 darks and 0 flats)...will be adding more data tonight. Yes i'm a glutton for punishment imaging on the shortest nights of the year hahah. Either way i am massively impressed.

    Looking forward to your findings, i have the STC Duo witch is awesome, so i'm intrigued 😊

    I'm excited to try it out for sure! Brilliant price too 😄 I think it'll compliment my l-pro max filter very well!! 😄
