Deep sky galaxies in Leo imaged on the 24th/25th March 2022:

NGC3599 (mag 12.02 spiral at 66 Mly), NGC3605 (mag 12.27 elliptical at 67 Mly) and IC2703 (mag 15.81 spiral at 51 Mly) were captured using an Altair 60EDF doublet refractor fitted with a 0.8 FR using an Atik 320e camera. Auto guiding was carried out with an SVBony SV165 guide scope fitted with a QHY5L-II-M mono camera, with auto focusing done via a Primalucelab Sesto Sensor 2 focuser. Some 47 x 2 min subs were captured in NINA giving a total exposure time of 1 hr 34 minutes. Images were stacked in DSS and processed in Adobe CS2.

Astronomy in the Mediterranean; Zoom talk

Martin Lunn MBE FRAS gave a spellbinding lecture of the development of Astronomy in the Mediterranean over thousands of years. The information and presentation was fascinating and informative. The contributions of various cultures from that part of the world to the understanding of Astronomy was explained as well as the very possible origins of certain Biblical stories such as the great flood. Altogether a surprising and thoroughly enjoyable lecture.





 

M51

M51 galaxy imaged with NINA on the morning of 24th March taken with an Altair 60EDF doublet refractor fitted with a 0.8 x FR. Image was derived from 30 x 4 min subs totalling two hours exposure.

The Sun in white light with a bridge camera

A Panasonic Lumix DMCFZ72, 60x optical zoom bridge camera, fitted with a Baader solar filter and mounted on a static tripod was used to capture 132 images of the Sun. The images were precisely cropped in Nicola's AstroCrop and the best 119 images were stacked and wavelet processed in Registax 6. The resulting image was post-processed in the Gimp 2.10.

Monochrome M42/43

An f/5.9, 66mm ED Apochromatic refractor was mounted on an iOptron CubePro AZ GOTO mount. An SVBONY SV305M Pro monochrome CMOS camera fitted with an LeNhance narrowband filter was placed at the focus and 60 x 20s exposures were captured of the Orion nebula with AstroDMx Capture.

55 of the exposures were stacked in Affinity Photo and Post processed in the Gimp 2.10, Fitswork and Neat Image.
