I am pleased to have got round to processing this. I have the luxury of still being on holiday at the moment, thanks to the 'quarantine' measures - we got back before they came into play, by 15 minutes, i.e. 3.45 a.m. - so I have some time to do this sort of thing. I would still like to be in France... : )

This is a Ha-OIII-RGB image made with the 12.5inch F/9 Ritchey Chretien from RC Optical Systems. It is an amazing set up, it really is, and was so pleased with the eagle data from the other day. Every sub was 10 minutes long, and from the data I used 17 blues, 12 greens, 11 reds, 30 OIIIs and 11 [size=100]Has. The integration time was thus 810 minutes, 13.5 hours.

Thanks everyone - take care...

Great Scott! That should be Great Simon of course. Had I somehow gone into hibernation for a few days or something. Last time I visited none of these were here. Had you perhaps been holding them back and then made a major release all at once.

There is so much detail in there, but given the integration time I suppose I shouldn't be surprised. But you've really successfully managed those surrounding stars extremely well, nice pin points that don't distract at all. Very pleasing.

Cheers,
Ray
