This is great stuff. I know from experience you can certainly get a lot more with the Ha with our set-ups. I aslo know from experience including an Ha-L in a colour image is not easy. So you have done well.
I don't know if you have tried it yet but do a series of say 8x15 mins in Ha in that area and you will be amazed.
That is one of my planned images soon with a decent amount of colour data.
BTW - Ashley at Precise is a top guy. I visited him a couple of times in Miami. By coincidence he had lived a few blocks, in São Paulo - Brazil, from where I was living at that time although he had left a few years earlier to move to Miami. Good chioce Astronomy equipment is much cheaper in the US.
He is a Swiss born American who worked in Engineering and now does this stuff on the side. He has some fantastic machining equipment. Ask him about the cap he does for the STL. I had one made because they don't come with one. He'll probably remember that he did one for me about 18 months ago.
He made my STL-FSQ adaptor and it works so well. He also made a Pentax 67 to STL adaptor too but through no fault of his, it didn't work, the lenses were not suitable for the rigours of AP work
