A colour inverted close up of AR11376 taken with the double-stacked PST and b/w webcam:

That is /great/. I love how three-dimensional it looks.

That's a cracker!! absolutely fantastic detail imagine what you will be able to achieve under perfect conditions. From what I am learning I think every etalon is very different in it's tuning, you look like you have a perfect match! your PST and this SM40 were made for each other.

Just pouring with rain here on top of all the snow so we have cold wet sludge instead

Snow showers here too. They started last night, just after I'd got all set up and was preparing to image Jupiter and the Io transit. Isn't astronomy fun? lol

As far as the double stack - yes, I'm dead chuffed with it. I also had a chance to try out the SM40 with the BF5, but the PST double stack easily wins. The SM40 on its own seems little different to a single stacked PST.

Great shots! Glad that double stack is working for you!

Thanks Mark. BTW I didn't need a reducing ring after all - the SM40 screwed on no bother. I used the two rings I had though to make an adapter for use with the ST102 and BF5. Judging by the results of the double stack PST though I doubt very much whether I will use that combo.
