Hi Doug,
my first clear night since my previous post was last night. It's all about patience these days isn't it? I used the triband filter with the Oak Astro attachment and hood last night on IC434 to compare to the internal filter in the Seestar. The moon was threatening to rise but didn't pop up during this stack.
It's not really like-for-like but I guess it's close enough. This one is the stack straight out of the Seestar with NoiseXterminator and darkened up a bit in Photoshop. It was about 30 seconds of post processing and not stacked externally in Siril etc. I'll do that over the weekend probably. It had about 30 minutes of acquisition according to the Seestar.
Interestingly, the stars don't look to be as blown out as my original post. I'm not sure if the colour is better or worse as I'm colourblind but the results seem good for what it is. I'm not sure that the results are THAT different from the original to warrant the Oak Astro kit to use my Triband. It's hard to say. Also, I didn't notice any vignetting to speak of, which was a surprise. See what you think anyway.
I'll need to give it a go on other objects to be sure. I'm thinking the Triband is going to help me with galaxies / clusters etc in my B6 skies.
