Soul Nebula (IC 1848) - Stellarvue 130mm @ f/5 - 2600MC - Antlia Triband RGB Ultra Filter - 7 hours  Robert Moses State Park Long Island 10/23/23

2600MC -  Gain=100  -  Exposure=300" With Antlia Triband RGB Ultra Filter. Guiding was great .25 - .45 all night... Rarely went above .5 arc/sec

This was a difficult process to get the color contrast between the Ha and OIII in photoshop. Another thing was I could juuuust barely squeeze this nebula onto my 2600MC chip at 670mm. Almost no cropping here.

Thoughts from this night:
I wanted to give the Antlia Triband RGB Ultra Filter its day in court. I dont get many nights out so I was wary of losing a night to test a filter. Ultimately I decided I wanted to use this filter because it has a more broadband profile, but is still quite narrow overall. This would allow me to capture SII and NII and Hb and both OIII signals I wouldnt get with my ALP-T. 



I was able to get 7 hours of usable data by the end of the night.

My thoughts on the Triband... For this type of emission nebula that have numerous narrowband wavelengths OIII, SII, NII, HA, Hb. I think this filter will shine. This target was one of these types I  believe and I am happy with the results. I believe I can see the other subtle wavelengths that the Antlia ALP-T would not have captured in this image. The Triband also has the advantage that the stars have correct color which I like a lot since this filter passes blue light. Just to clarify, I think the ALP-T is the best dual narrowband filter out there for Ha OIII targets. On the other hand the Antlia Triband is being marketed as a filter that can capture broadband objects as well. This filter has a much broader bandpass. Does it live up to that claim?

The next night after I imaged the Soul, I took 5 hours of data on a broadband target (M45) using this filter. I will be processing this one next and posting when completed. At that point I can provide some thougts on the Triband RGB Ultra on a broadband target. 

As for the Soul, I think this filter did a great job and captured a lot of the subtler wavelengths of light a dual-band would not have, while filtering much of the other wavelengths that would not be desired. Another advantage is RGB stars and better color balance. I think this was a good choice for this type of target. I'll see how it does when I process M45...

Please tell me any thoughts or improvements I can make if you have a moment. It's appreciated.
