I managed another sketch this morning with the 24 F4.5 this time. Skies a bit claggy but the aperture compensated, similar overall view to Sunday morning with the 18. I suspect the coma was a bit larger than drawn but the clagg was preventing me seeing any more. 13mm Ethos again but x208 in the 24. Noticeable movement over the 45 min period of observation (see inserts). I defocused the star field to make magnitude estimates and put it similar to HD 111527 at mag 9.6. It was definitely fainter than HD 111383 at mag 8.8. Perhaps Im not seeing all of the coma but mag 9.6 looked about right to me.
