A close in 'still' shot to complement Ewalds's nice wide field moving image
~ 7.15 pm 5'th Feb Thames Valley U.K
Sharpcap gave me a nice comet stacked EEA image to admire while I was capturing 185x5s, 60x20s and 19x40s exposures using an ASI1294 MC PRO camera, VX12 300 mm F 4 Newtonian, aplanatic coma corrector etc on an Ioptron CEM70 mount. Short exposures because movement was fast and especially at f 1200mm.
Conditions not great - Bortle 7 - sky somewhat unsteady then deteriorating - but good enough. Processed in PixInsight - after some difficulty working out how to align everything and sort out noise and gradients etc --managed to extract a reasonable starless comet image and a separate stars only image near the NGC1798 cluster. Only about 50 min of data in total. Some sort of tail just about visible - but wrong place for the ion tail.

Great capture of this pair.
Kind of unique too since it will never be captured again, ever

Thanks Menno, yes indeed quite a contrast to so much else that we observe that is unchanging on our timescale. Glad that I managed to get a picture at all even though conditions not great. Tim
