I just tried this on a fully processed OSC image that was imaged thru an L-eXtreme filter. It worked quite well, the best I've done so far. Thank you so much, Monty

[@Steve-br7wt]

Seriously good stuff. I can’t wait to try with some of my data. Thank you for this!

[@vishadow]

This is fantastic!! I'm now able to make some of the OIII data pop from my OSC camera using a dual-band filter.

[@rockymountainastro1239]

So glad to hear it helped!!

[@jacobtaylor7853]

I think the golden egg item in your processing videos is the Convelution step. That has been a complete game changer with my background and I can't thank you enough for that tip! I'll definitely be boosting my Oiii data as well when Nebula season is back!

[@rockymountainastro1239]

Awesome to hear! That was a game changer for me as well. I used it today! So glad I could be of some help

[@bowen2307]

Thanks a ton man!! So helpful. Great work with the tutorials

Youre welcome! and Thank YOU!

Wow amazing tips ✊🏻😊 Thank you Sir

[@DrewJEvans44]

So well done Teagan, and well explained as usual.

[@rockymountainastro1239]

Thank you, Drew! I'm glad to see that after this long, this still helps people.

[@jukkapaavilainen1973]

Thanks for the demonstration. Was easy to watch. I have always used the same method, but with LRGB noise reduction. I need to test using the convolution instead. Color mask's are also great to use with data like that. Nice looking image you have =)

[@pyo41364]

Thank you ... right when I needed this ...

[@rockymountainastro1239]

Fantastic! I hope it helped (:

[@eirikkittelsen9787]

Great informative video! I finally made my bi-color images look as I visualised and hoped for!! Thank you so much!! Best regards Eirik

[@rockymountainastro1239]

Very nice! Glad I was able to help. CS

[@uwedeutermann1163]

Nicely done!!

Teagan - I can't thank you enough for preparing this video and sharing the information. I used your approach with recent Ha and O3 data on the Heart nebula. My original processing produced a nice image, but, it had almost no Blue! I did a new processing of the data using your approach and came up with a Heart image filled with beautiful deep blue regions. It also enriched the reddish color in many areas. I was wondering how others came up with all the beautiful Blue and now I know. By the way, I found your explanations easy to understand and follow, well done! Thanks again and clear skies. Steve

[@rockymountainastro1239]

So glad to hear that I could help! Getting that blue color to pop is much easier to do when you are imaging with all three, Ha, Oiii and Sii. I have recently gotten a 3nm Sii filter and the differences are drastic. If you do not have, one I would highly recommend it! Thank you for the feedback! Clear Skies (:

[@steveking3611]

@@rockymountainastro1239 You're welcome Teagan. I remember following you on the other website (Astrophotography Forum?) when you were just getting started. You have certainly come a long way. I do have an Siii filter and just finished combining to form an SHO image. I used the RangeSelection approach to boost both the O3 and S2 images before combining with the Ha. I then used the blurring technique on the combined image before using LRGB with the Ha as the Luminance. It worked perfectly. Your suggestions are now part of my workflow! I posted the SHO image (Heart nebula) at this link: theskysearchers.com/viewtopic.php?f=66&t=14292 Cheers - Steve

[@jamesastro1134]

Excellent tutorial, thank you!

[@chazparvez4970]

Thank you. Very informative.

[@Andyportervt]

Hey Just wanted to say Thanks. That was an excellet tutorial. I quickly reprocessed some old data. The original was ha o111 and s11. the reprocessed data in ha and o111 looks better than my old stuff uing three filters. Would love to see more of the same. Obviously i have subscribed Cheers Andy

[@rockymountainastro1239]

Awesome! So glad to hear it! Thanks for the subscribe. Hopefully Ill be able to post some more videos here soon!

[@DamianVines]

Really great! Thank you!! I was struggling too :)

I was like this kid is on Adderall and then realized I had my time on x1.5 lmfao. This is 👏 amazing

[@abrahamshadbeh7223]

Ive stacked my Ha and Oiii data and was thinking of using your tutorial, some steps missing though, such as DBE? Im new to PI and have not really enjoyed processing as much as the data collection itself. I use a dual camera system with two telescopes everything identical. Is there anything missing from your tutorial that would make it a more complete one? Just FYI, you did go pretty fast but it was very complete and really helpful.

[@midnightlightning1]

Great video, I am just working through it with C49 data. One thing I'm confused about. You say to remove the OIII mask before using PixMath. But then after using PixMath you appear to remove the mask? Should the OIII mask be on when using Pixmath?

[@alecalden216]

Hi there, seriously good work. Certainly added to the blue but I am not there yet. Any ideas on why when I overlay the Ha image over at the end it tends to put a bright blue ring around the larger stars? Thanks for all your efforts, without which this would be an even more difficult hobby.

[@rockymountainastro1239]

Hi Alec, I am sorry that I did not see this. I noe starnett the stars out before combining and then add them in photoshop. I also have a tutorial on this using my Pelican Nebula SHO data.

[@mostafametwally1]

Have you always combined your images in the non linear state?

[@rockymountainastro1239]

Hi Mostafa ,I have only done this with Bicolor images as I never get a good result combining them in the linear state. With tri-color data, I absolutely combine in the linear state!
