4th April 2025 – Friday night observing

For the first time in a while, we were able to open on Friday 4th April.

Mark had the SeeStar S50 and Chris was using the RASA 8. Despite the quarter-Moon and fairly poor seeing, decent images were made.

Mark’s shot of the Moon was a single imageand without processing.

Chris had the Rasa 8 telescope with an Apc Imx571 colour camera. He took 109 30-second images and processed them with different filters to bring out the Ha and Oiii wavelengths.

The third image is a composite with the addition of 20 120-second images taken with an NBZ uhs filter, specifically designed to enhance the contrast of Ha and Oiii emission nebulae.
