Hi Folks With clear sky a rarity in the UK I’ve only just had chance to chase the comet C-2022 E3 ZTF. I caught it on 6th Feb under a full moon, bortle 7/8 sky, light high cloud and in front of a very crowded star field all of which is making it tricky to process and I’m hoping for some advice please. I use Astro Pixel Processor, Affinity Photo 2 and StarNet v2. Although I know it’s very powerful I know I’m not going to get PixInsight - waaay to complicated for me. I followed the basic procedure in this video: My efforts are in the attached photo sequence. I’ve done little additional processing to it beyond removing light pollution. My main issue is to find a way to minimise the ghost star trails on the comet plate (4). I used APP’s LNC MAD rejection set to 8 and 1.5 as suggested in the video, but honestly I’m not even certain what that means… Any suggestions which might help me improve this image? Thanks 😊

As far as I know, this is the very first image of a comet I have ever taken. It is of the famous 29P Schwassman-Wachmann which undergoes outbursts every so often. Very bight nucleus and extensive coma. 930 seconds unfiltered through a 0.4m Dilworth. Taken 2023 Jan 14 - 23:30 From Tacande Observatory.

Hallo, These days I try to get some photos of the comet ZTF C/2022 E3. Soon it starts to move faster relative the stars and there is a need to change the motor speed in the mount. How much the comet's or astroid's speed (dRA, dDEC) are you can get from NASA or CdC (Skychart) but the information is in wrong format. I did a complement to my calculater of angles with a relative speed calculator. From degrees/hour to arcsec/sec: http://www.astrofriend.eu/astronomy/astronomy-calculations/angle-conversions/angle-conversions.html I haven't got a clear sky after I finished this calculator and haven't a chance to test it so maybe something wrong, but looks to do the right calculation. Let me know if you have a clear sky somewhere and can test on a comet. /Lars -
Hi all, hope you are doing well.. So i did a test run on imaging the comet from my B garden in Greater London last night. Sadly, the clouds arrived as soon as id set up, very thin but definitely present. Lit by the very big moon low behind the house i was pointing at. Because of the clouds, i only managed to get 24 subs, no calibration files. The calibration files were my middle aged brain failing me again and not telling me to take them before i packed up and went upstairs. I got a little nice extra though with M10 in the image. SO, yes...disappointing, but im trying again in a few days and will be better prepared. Canon 4000D stock 70-300mm f/5.6 Canon at 300mm 1600 iso Star Adventurer 2i 24x120s lights Debayered in Pixinsight and stacked in DSS. Edited in PI and PS. As you can see, i also had a very dirty sensor...thats now been cleaned. LOL I'm not fishing for positive comments, just thought i would share with you all for fun. I will make sure to update this thread on Thu after my second attempt. Have a great day . Cheers

Hi, my name is Jay Peacock and on January 3rd, 2022. I was observing Comet Leonard through my Celestron 9.25in SCT Evolution for the 3rd day with only a day or so in between observations due to bad weather here in FL. (mainly clouds and light rain). But on the night of January 3rd, 2022. I noticed there was two objects in my eyepiece, one being easy to identify as Comet Leonard from observations the nights before, and the other I assumed was just a background star. Upon inserting my Celestron Skyris236C eyepiece camera and refocusing my telescope from my eye to the camera, what I found was shocking. Both objects were comets, one being the known Comet Leonard A/2021 and the other I have yet to be able to identify. I have not been able to locate anyone that has more information on this conjunction of comets, but I do believe it could either be a piece of Comet Leonard that broke apart during A/2021's closest approach to the Sun, which also occurred on January 3rd, 2022, or this is a newly discovered comet possibly, and strangely enough, I would be the person that discovered it 😮 ! I was able to capture 3 or 4 videos of the comet conjunction at which I was able to process and stack the images to get a still photo, not sure the videos will post but I will attach one of the stacked images I processed or two for those of you interested in seeing a possible once in a lifetime comet conjunction. I will try to add a video also if possible. And thanks for those who stop by and comment, also if anyone else has any further information on this conjunction, I am very eager to hear more. (Really hoping I discovered something new ) 17_52_52.avi

From the album: Imaging Challenge #17 - Through the Eyepiece
I just tried to see the moving of this object. I made 20 frames with my Huawei P10 smartphone, with the monochrome camera. My star tracking is not so sharp, I have alt-az mount, I used only 10 sec expositions at ISO 1600. The shots was taken in every 10-12 minutes in this time intervall: 00:16-03:53am 2018. 08.16. Celestron Nexstar 8 SE, 25mm plössl eyepiece (magnification 80x). Of course I used a good adapter too. Frames has added with Gif maker pro mobile application.© smisy

Taken Saturday night 9 April17. I set PHD2 to follow the comet which it did while I images 12 x 600 seconds. But then, if you look closely you can see, the Comet passed a star and PHD2 could not decide which bright object to follow. So crashed . Needless to say, I managed to create a GIF out of it. :) -

Was really chuffed to catch this comet, especially with the two tails. This i believe is the 5th comet i've caught 'on film' as it were. Along with Panstarrs - ISON - Jacques, and Lovejoy (forgot the numerical names). Equipment: ED80 - / 350D -/ EQ6 -/ CLS clip -

Comet C/2014 Q2 (Lovejoy) taken on 01/02/02. Single 30s frame captured using Lodestar Live & Lodestar-C with INED70 and F6.3 reducer. -
From the album: Others
Equipment: Canon 7D2, ISO1600, Sigma 150mm f/2.8 macro at f/2.8, Astronomik CLS CCD filter, 161 x 30s exposures. Took more but rejected a load due to cloud. Tracking background stars unguided with lousy polar alignment. Processing: Starting with PixInsight, flats, star align, comet align, stack, stretch, DBE, curves, photoshop. Above is only a comet aligned stack. I've tried to optimise viewing for the tail in this image. -

95 x 4 second livestack in Sharpcap using a 14¨ Dobson. This was a session of mixed emotions. From despondent to elated. After battling clouds high winds and bad flats, I finally managed to get this 6 minute stack at 6.55 am while the comet was at about 48 degrees Alt. This was shortly before sunrise as the comet rose into a clear area of the sky. It was much brighter than I expected. I could even see the head of the comet, with the scope, when it was visibly light outside at 7.16 am. Expecting this comet to brighten several fold in the next week or so. In this image you an clearly see the reddish dust trail and the bluish ion tail/cloud. There is also some good detail towards the head This image is a slightly cropped direct output of a livestack using Sharpcap. No other postprocessing or enhancement This was the best of multiple 5-10 minute stacks I made between 6 and 7 am. The detail in the head always showed up within the first couple of minutes of stacking. More details at Comet Leonard C/2021 A1 AT 6.50 AM December 5th (EAA) ( Mike Dobres ) - AstroBin

Comet C/2019 Y4 (ATLAS), currently 160 million kilometers away from the earth and motoring along quite nicely. This short timelapse consists of 100 x 60 second images taken over 150 minutes with a ASI533MC-Pro camera and William Optics Zenithstar 61 refractor captured with APT and post processed using PixInsight Blink for the animation. The bright star lower right is Althiba IV Comet C2019 Y4 ATLAS.mp4 -
Hi, I and my girlfriend are now drawing plans to catch the comet C/2019 Y4 Atlas on photo. It's just a few weeks until it reach it's maxima for us living in the Northern hemisphere. We belive there are a lot of others that plan to do the same. We use my travel mount Star Adventurer and two cameras with telephoto lenses, a bit overloaded but easy to bring to a dark place. I have updated my comet page with examples that belong to this comet. Maybe could be interesting or of some help for you ? UK isn't far away from Sweden and the circumstances not to different from ours in Sweden. http://www.astrofriend.eu/astronomy/tutorials/tutorial-comet-photography-planning/tutorial-comet-photography-planning.html I have also this comet related page that I wrote long time ago: http://www.astrofriend.eu/astronomy/tutorials/tutorial-find-comets/tutorial-find-comets.html We wish all of you a clear sky and that you get nice photos of the comet ! Lars and Gunilla

Hi all! I've been out of the game for some time now but nice to see familiar faces on SGL! I hope everyone is well and keeping sane and safe! Lots seems to have changed! New cameras, new software, new lots of things! It's hard to get back up to speed after a few years. My Dad (Mick J) keeps me updated. The general image standard is now so high it seems! I have a bit of a natural break in work and life things so enjoying some time in Crete with other half's family currently. First time using portable set-up for me and to be honest a lucky capture with the comet in the frame mostly by accident! Approx 55 minutes total of 30s frames and some 10s frames for M42 core, ISO 400. Modded Canon 450D, Samyang 135mm F2. Skywatcher StarAdventurer. Similar version of lockdown here so taken from city location and passing cloud but happy to just have some time to enjoy a bit of hobby time! Processing gradients wise was tricky!

So, ATLAS has disintegrated, and it won't provide us a great show in May. But there's another comet that could reach naked-eye visibility in the same time that ATLAS' debris reach perihelion. It's C/2020 F8 (SWAN). It's had an outburst recently and it could reach 3rd or even 2nd mag. And it's looking pretty good from the southern hemisphere! Here, in the north, we'll be the only ones that will see the perihelion of the comet. So let's see if we're lucky this time... No one knows what could happen, but I have hope. It was only discovered on March 25th, so there's still time to see how this comet reacts.
