Looking good Carole. You finally got some decent imaging time with the Esprit.

Thanks, but it you read the text, I "borrowed" some Oiii and Sii from an image in 2014 to add to the little I got with the Esprit as I ran out of clear skies.

Lovely image Carole and to me a good way of building up the integration time . I've decided to keep all my subs from my first year in astrophotography so I can build up the integration time on some of the targets later this year. Seems like a decent strategy given the poor weather for long periods.

Mainly taken with Esprit100 and 0.79 focal reducer/Atik460EX on HEQ5

However it was almost a full Moon and I didn't get a lot of Oiii and Sii and no clear skies forecast in the near future, so I utilised some Oiii and Sii from 2014 done with my WOZS71 and Atik383L, this increasing the Oiii from 40mins to 2 hours, and the Sii from 40mins to 1 1/2 hours.

Ha entirely from the Esprit/460

Ha 12 x 600 (2h)
Ha 8 x 900 (2h)
Ha 3 x 600 binned x 3 (error!! but decided to combine it). 30mins
Total Ha 4 1/2 hours.

Oiii with Esprit/460 8 x 300 binned 40mins
Oiii with WO/383 9 x 600
Total Oiii 2 hours

Sii Esprit/460 8 x 300 binned 40mins
Sii WO/383 5 x 600 50mins
Total Sii 1 1/2 hours

Total imaging time 8 hours

I like that. The colours are spot on.
