The Small Sagittarius Star Cloud (M24): Using a 3D printed star diffraction spike filter fitted to the objective lens of an Altair 60EDF refractor (see image), an additional 48 mins each of SHO and RGB data were taken (96 mins or 1.6 hrs total) which was then stacked and star aligned with the previous integration done on the 11th June which comprised 48 mins of RG/SHO data. This gave a combined integration time of 144mins (2.4 hrs) in total which was combined as an RGB/SHO composition with the brightest stars showing diffraction spikes from the filter.

The Coathanger: I captured a further 15 mins of RGB data taken with a star diffraction filter fitted to the objective lens of the scope, to combine with my previous integration of this target which comprised 68 mins integration time. This gave a combined integration time of 83 mins in tota, with the brightest stars showing diffraction spikes to enhance their appearance.
Noctilucent Clouds: During my imaging runs a fairly bright display of Noctilucent Clouds were observed low on the western horizon at about 11:30pm. Some 15 x 4s images were taken using a Sony ZV-E10 camera fitted with a 12mm F2 lens at ISO 500 to capture the clouds as they sank down towards the horizon with images being taken every minute. Using Adobe Photoshop's animation function, the images were then made into a gif to show the cloud movement over a quarter of an hour. A single jpeg image was also processed to show a static view.
