    Just a plug to observe this comet, as it is now very conveniently placed in the sky for those in the northern hemisphere. Changes night to night.

    It certainly is. I measured it at mag 5.6 this morning with lots of detail visible in images.

    Sleeker ion tail when imaged last night. The comet’s hood lends it the appearance of a speeding bullet.

    Gideon van Buitenen has produced a really nice simulation of the comet’s appearance which you can find here:

    It shows the PA of the ion tail swinging around very rapidly over the next few days.

    Not much luck with clouds on the Kent coast but I can’t remember the last time when a *bright* comet was circumpolar (from UK). Must be unusual timing and orbital geometry. Hoping for a favourable break in weather over next few days before full moon!

    I was lucky last night

    Canon 77D with 250 mm . Exp. 10.sec. ISO 3200.

    Used Slooh Canary 2 on the night of 27 Jan at 0052 to take this image. Subsequent processing with Affinity PLus.

    This Comet is just visible in 10×50 binos here in eastern Scotland.

    Captured this eve (midpoint) 2023-01-28T19:12. Lovely ion tail.

    Development of ion tail into at least three streamers.
    MIDPOINT = ‘2023-01-29T20:59:22’ /UT of midpoint of exposure

    David. Yes the ion tail is very active again. Your images are excellent. Your fast RASA is ideal for this.

    Finally had some clear skies tonight and I just made this observation. Using HR3082 as a comparison star, I estimate a Mv~ 5.5

    You guys up in the frozen north have it lucky.

    I find it very frustrating that Polaris is only 28 degrees above the horizon from here. Even worse, my fork mount won’t allow pointing at anything above a Declination of 75N or the camera hits the mount. Guess where C/2022 E3 is tonight …

    With luck it will be far south enough to give me a chance in a few days but, of course, the moon will then be very near full.

    Life, don’t talk to me about life.

    P.S. now the ****ing filter wheel has just packed up and I must go back to the dome to see what needs to be kicked into submission. Almost always a Windoze/USB failure.

    Paul – That is why I have never liked fork mounts although the price I pay is meridian flips. The comet was really nice tonight despite the bright moonlight. I get it to be 5th mag now. Here is a picture of my telescope effortlessly pointing near to the pole taken while it was taking the picture in the inset. I don’t get many chances to take a picture like this!

    Yes, we win some and we lose some. I don’t actually lose very much useful sky as Dec +75 reaches a maximum altitude of 43 degrees and a minimum of 13 degrees from here and I don’t much like doing photometry below 30 degrees altitude unless it is really necessary. I have always really loathed meridian flips.

    HL CMa was nice and high in the sky here (just to make you jealous 🙂 — there are advantages to having a low celestial pole — until cloud stopped play. 1 made it V=12.33 tonight.

    In my experience I would have fork mount any day over a GEM. The problem with cameras and ancillary equipment fouling the mount in the fork design is not a problem for Newtonian or Nasmyth designs or indeed prime focus SC’s like the Celestron RASA . Meridian flips in a GEM are amongst the most common irritations I have with my SC on a GEM. Image attached of my last large Newtonian, oh how I miss it!
