COMET C/2022/ E3 (ZTF) - UPDATE

[Elp]

The one listed on sirils website is easy enough to follow. Helps if you know beforehand about doing your calibration to your images.

Also I found Adam Block's video on YT very good, he uses PI to process but he doesn't go through it as a full tutorial, just the theory step by step. If you're going to stack, at some point depending on how long you've imaged, most of the work will come from your post processing manual skills as you'll likely have to perform some sort of subtraction to the comet image to remove star trails, layer masking etc.

It was certainly an experience doing this. If you're just editing one image or a handful it's much easier.

Wonderful image Nigella!

I hoped to get a quick peek at it this morning before work, had the binoculars ready, but it was too cloudy!

Heavens Above is stay right on it with its position. 

It is really moving along now, or as we say it out in the country, "it's really scooting a boot!"!

Or hauling A##e as some US folks say.

Thanks, my first stacked comet image. Another stacked image from C/2022E3

DSS comet stacking does do strange things it used to work really well. SIRIL has comet stacking which is what I ended up using on neowise

Just been reading a post on gilthub and I will next DSS comet stack do the following, mark the comet on just 3 frames. Mark the first and last frame and which ever frame is chosen as the reference frame.

Is the comet visible with the moon being what it is at the moment? Or are all these sightings after moonset.

You can still see it with bins or telescope. It with naked eye unless bortle 1/2 I hear.

Brightest I’ve seen it tonight in the 15 x 70 bins, and although I might be imagining it I’m sure it had a green tinge to it. A nice bright nucleus showing but still a diffuse spherical shell rather than a tail. I’d say the mag was somewhere between 5-5.5 currently.

I got the 20x80 bins on it last night, I would have rolled the obsy roof back but it was blowing a gale. I must say it's incredibly well placed for Northern observers.

Yesterday evening Heavens Above had it listed as Mag 4.8.

Of course, this morning was fogged in for me.

Just saw the comet with my new 7x35 binoculars, even with the strong moon glow and hazy conditions, as good  as I have seen it. No colour or tail, but nice to have a view on closest approach to today.

[GrumpiusMaximus]

Had a bit of a mare yesterday night looking for it through my 20x80 bins.  Eventually I got clear skies after a day of heavy cloud.  I have no idea why but I had trouble finding it, which feels utterly ridiculous to say but it was at what felt a much higher inclination than the charts suggested.  The charts were right, of course and it was my complete lack of recent practice that was the issue!  In a 'typical me' situation I ended up getting there by first finding M81/82 - but I'm strange like that.

When I actually found it, it was great and I was somewhat embarrassed that it had taken as long as it had given how obvious it is.

 I just took an image with my iPhone, enlarged area. The bright smudge in the centre of image is the comet, and the star just above it HIP 29997 is magnitude 4.75 for reference.

How did you do that in Siril Kat? I assume manual preprocessing.. do you have a link to an idiots guide? 

Yes, manual preprocessing. It was the first time for me to do manual preprocessing, so a bit of a noob, but it worked out fine! https://siril.org/tutorials/comet/

It has been a pleasure following Comet c/2022/E3 (ztf) the past couple of weeks. Amazing how much of the sky it has crossed in such a short time. Not managed to see any hint of colour through my binoculars yet.

[Muc]

Got my first view last night since I last saw it I  early Dec. January was a near total cloudy month. It wasn't amazing visually with the moon and light pollution. But seeing it's movement at x60 and above among nearby stars over 10-15 mins was amazing.

Thanks Jeremy, much appreciated. Hope it's clear this weekend to try again.

What type of tracking mount did you use HEQ5? 

And how do you get the starburst effect on the orange star is it Software?

Excuse my questions but I only have basic equipment with a static tripod and DSLR
