My last process of Carina for this year. Been sitting on this data for months, but it's taken me that long to find the time, and to get the confidence in my processing skillz to do it justice. A recent purchase was Astro Pixel Processor, which does an amazing job of pre-processing Ha data from a OSC camera. Yes, yes I know it's not the same as a true mono camera, but it has added a whole lot of structure and detail that I just wasn't pulling out of the colour data.

Mono cam is high on the shopping list for 2020, can't wait to have a crack at my favourite DSO armed with that!
