    Integration time:
    * SII 38 x 300s (190m)
    * Ha 50 x 300s (465m)
    * OIII 134 x 300s (670m)
    * Total: 1325m/22h05m

Notes

9th August 2022 Gathered more Ha data to take total integratime time over 20 hours. Only two dropped frames on a night of varying transprency where I nearly closed the observatory prior to imaging because of the amount of approaching cloud. I decided to let it run and let NINA handle re-centring etc should it be required. Now ready for processing.

NGC7822

The new wide field target for the current period of good weather is NGC7822 / SH2-171, an HII region in Cepheus.

From latitude 52° North this target is at it optimum altitude now and will continue to be available for several hours per evening well into the darker nights of autumn.

2nd July 2022 I ran the 200PDS on the Cave Nebula in narrowband and the Askar on the Cygnius Loop in OSC. Amazingly my tweaks to the AZ-GTI mount seem to have made the guiding work and although the guiding standard deviation was horrible the result was very tight round stars on the Askar. The guiding on the Newtonian was awful too and I think that the extreme humidity was affecting the seeing quite badly.
