About this image

Tried for Comet Leonard in the evening sky this evening, but just too low in the murk to catch it. The comet lay just below the two faint stars nearest the horizon which are 60 Sag and Omega Sag.

David, Could you let me have the raw image files please? I have ways of processing which may reveal something. I'd be interested to try anyway.

David. Thanks for the files. It's a shame that they are JPEGs and not raws since I think you were very close to getting it. This image is a stack of 5 of your JPEGs with median background removal. The JPEG compression leads to banding and various artefacts but you can see 62 and 59 Sgr which are about the same altitude as the comet (both around 4.5). The comet should be in the middle of the box but probably too much murk since there is no sign of it. Good try though.

Thanks for trying! It was worth the effort, a lot of people stopped by for a chat, mainly about the Moon and Venus, but were intrigued to hear about the comet. I was imaging from the SW coast path on Salcombe Hill with a clear sea horizon.
