I knew I may've made a mistake with the O111 data. I didn't register it early on and I think I relied on Photoshop's auto align feature which is not that great.

OK fixed it now, same link. Thanks for spotting it, I did not look at it critically enough.
A new setup so feeling it out for optimum settings and procedures.

lovely vista Greg.
This short focal length imaging makes for easier data capture than the close up stuff hey!

Ok maybe I have missed it ...but what scope/lens took this?

The colour version is ok too but I quite like the Ha only version.

Pentax 645 300mm EDIF F4. Its got 2 ED elements. At one stage in the past they were worth US$4500, not now of course.

I quite like it but it does seem prone to reflections/flare. A poormans FSQ with reducer. I also have a 1.4X extender which will give F5.6 and 420mm focal length. I haven't tried that yet. Some objects lend themselves to extreme wide looks. It holds focus all night it seems so its very user friendly.

We're holding out for that SHO version. Judging by the H-alpha only, it is going to be gorgeous.
