Sun in White light and Ha montage: Two images of the Sun taken on the 16th October; the white light one was taken through partial cloud with a Sony ZV E-10 milc camera using a 350mm lens protected by a Baader OD5 filter with 20% of 49 frames stacked in Autostakkert!4, wavelet processed in Registax and post processed in Pixinsight Solar Toolbox and Adobe Lightroom. The Ha one was taken using Astro DMx Capture with a Player One Apollo-M-Mini camera attached to a Lunt 50 Ha scope, with some 20% of a 4,400 frame SER stacked in Autostakkert!4, wavelet processed in Registax and post processed in Pixinsight Solar Toolbox and Adobe Lightroom. 

LDN 1355 (The Helping Hand nebula): 16 hours of LRGB data taken over the nights of the 17th and 18th October using an ASI 533MM camera attached to an Altair 60EDF refractor fitted with a 0.8 x FR. Data integration and processing were done in Pixinsight, with final adjustments made in Adobe Lightroom.

Comet C/2025 A6 Lemmon with Orionid meteors: 23mm and 70mm lenses were attached to a Sony ZV E-10 milc camera mounted on an MSM tracker to take some time-lapse images of the comet rising in the dawn sky. On both runs two bright Orionid meteors were captured in the same field of view in two single frames from each of the runs. The 23mm Sigma lens image was taken at F2, ISO 800 with a10s exposure and the 70mm one at F4.5, ISO 100 and 10s exposure. Processing was done using Adobe Lightroom.

Comet C/2025 R2 Swan near M16 & M17: A wide field image of the green comet passing close to the red Eagle and Omega nebulae in Sagittarius on the evening of the 17th October taken with a Sony ZV EV-10 camera mounted on an MSM tracker using a 23mm Sigma lens at F2 and ISO 800. This is a stack of 59 x 15s exposures, giving ~ 15 mins total exposure time. The Sony ARW's were stacked in Adobe Photoshop 2025 with final processing done in Pixinsight and Adobe Lightroom.

Moon (18th October): 20% of a 6,125 frame SER of the slender decrescent moon taken on the morning of the 18th October with an ASI 533MM camera attached to an Altair 60EDF refractor fitted with a 0.8 x FR following a deep sky imaging run. Data were stacked in Autostakkert!4, wavelet processed in Registax and post processed in Adobe Lightroom.
