A couple of the better non-Perseids from the other night:

 

This one doesn't look like a Perseid, nor is it in the right direction.  Closest radiant showing in Stellarium is June Scutids, however, I think the radiant is closer to Vega so a bit North of that.

This one has that green look but the radiant is well away further South from the Perseid radiant.

Hoping to get better at IDing meteors, but just going through these and processing them is taking plenty of time in this busy time of year. smile.gif

I managed to capture a couple good ones this morning, despite my neighbor turning on lights outside after midnight that remained on all night.  I cannot wait to move away from those people!  I have been looking for a new place away from stupidity since November.

 

This one was with my Canon T4i and 15mm lens.  It must have been a really good one.  My other camera with the 28mm only caught the very bottom of it and the rest was out of frame.

Camera: Canon Rebel T4i (modified)

Lens: 15mm f/2.8 sigma

Exposure: 15sec at f/3.2 and ISO 1600

 

This one was with my Canon T8i and 28mm lens.  To me it has the appearance that it started in the lower right and made its way to the upper left.  However, if it was in fact opposite of that direction then it would be almost certainly a Perseid.

What is your process like when you capture video?  Do you just capture a long video and go through it faster or something like that?  Since I mostly capture images I typically just cycle through them with xviewer (default photo viewing app in CentOS).  It takes me about 1/2 second per image until I stop on one with a meteor and note the frame number.

For going through many stills I've always used C1P. I can flick between images and see if anything has moved/changed from one image to the next.

 

For footage, I used to just play through at normal speed. Very time consuming, and easy to fall behind with more than a few clear nights close together, meaning I was always buying new HDDs.

 

Basically my process now is:

1 - Make notes of start times/ISO and anything else relevant while recording.

2 - Monitor the "meteors live" page here throughout the night, noting the corresponding clip/time of any events of interest that one of my cameras may have captured. With over 200 cameras in the UK it's rare for anything to be missed unless there's a lot of cloud around, in which case I'm likely to be clouded out as well.

3 - Check the footage.

 

I record 20 or 30 min long clips depending on camera, and stagger the start/stop times since I have one camera upstairs (pointing out of the window in our spare room), and two downstairs/outside, so I have time to go between them.  It used to be 10 and 30 min clips but last year I hit stop/start on a 10 min clip just as a fireball exploded so I started using 20 min clips instead. Even with 20 min clips, last night I managed the same feat with this bright July Pegasid - I didn't bother saving the clip.

 

As far as PI vs. Photoshop, I might not be the best to answer your question.  I suspect there are a fair amount of things one can do that the other can't and that goes both ways with some overlap.  Though I can't say I've used any form of photoshop for many years and I also can't say I am familiar with everything PI does as it has a huge number of processes and scripts even at the default level without any add-ins.  PI has a huge learning curve.  It took me months to start feeling comfortable with it and I still occasionally come upon a very useful feature that I wish I knew about long before.

It does sound like a useful tool to have in the kit. I'll have to give it a try sometime.

 

Now that I've spent some time looking at my captures from 2 nights ago I got a really nice indication that things are picking up.  That is at least 4 of them I suspect are Perseids.

 

These are 3 of the suspected Perseids.  I'm skipping the best one as it was mostly off frame, of course! wink.gif

One of my cameras caught a small kappa Perseid fireball a few nights back (still have not got round to uploading a few recent clips including that one), and I've observed a few July Pegasids here, but so far no PERs.

I have on occasion used layers and a screenshot of Stellarium to try to work out potential radiants, but it is quite time consuming. Like you say, not enough time for everything!

I keep missing everything lately, but there has been an outburst of alpha Capricornid fireballs on the night of the 25-26. That night was semi-clear over here, but must have been too early as none of the cameras caught anything significant.

 

Hope others have been having better luck!

I wasn't able to set up that night but I did set up just one camera last night around 11pm.  Got a couple bright ones. 

 

27 meteors in 3559 frames.  About 5.46 meteors per hour using 28mm lens.  Best rate I have seen in a while.

Good catches, and nice to hear rates are climbing.

 

We have some clear skies tonight, and cameras are running here so just a quick note. Looks like there are still fireballs about tonight. UKMON cameras caught this one earlier.

I set up just one camera at about 2am this morning.  Caught a few nice ones this morning.  Not quite the bolide I am after but I feel like I am on the right track.

 

Also I watched the sky for about 50 minutes last night standing outside with some friends.  I counted 7 meteors in about 50 minutes despite the bright moonlight.

 

These 2 are likely Perseids.

This one definitely was not a Perseid.  It lines up with at least four radiants so I don't think I'll know which one it could be if it's not just a sporadic.

Not bad going Eric. Good to see you had some clear nights there.

 

What little clear weather we've had here  recently has yielded only little meteors, but I finally got round to uploading a few slightly larger events that the cameras caught earlier on in July.

 

First one is this small fireball in the distance - somewhere over SW UK:

https://vimeo.com/851062415

 

This bright sporadic was a little closer, and was reported:

https://vimeo.com/851066104

 

The upward facing camera caught this double flaring phi Piscid meteor:

https://vimeo.com/851067049

 

And lastly here is that small kappa Perseid fireball:

https://vimeo.com/851067920

 

Looking into the future I see some possibly clear nights coming up towards the end of the weekly forecasts, so hopefully I should be able to catch some pre-peak Perseids at least - there have been a couple already, but very dim!

Nice catches Leo.  Good luck with the weather. 

 

I just got my 2nd Canon T8i back from being modified so next time I set up I can roll with 2 T8Is. 

 

Did you happen to see the video of the bright fireball that is up on spaceweather.com?  5 times brighter than the full moon.  Must have been quite an experience seeing that.  Archive link: https://spaceweather...th=08&year=2023

 

Clear skies,
Eric

Thanks Eric.

 

Having that second camera running should make all the difference, and in time for the run up to Perseid max.

 

Yep. Saw that video on spaceweather.com. Quite an impressive event. Not often they get significantly above full Moon brightness.

 

Fingers crossed there will be a few more in the nights ahead, and fingers crossed for clear skies, preferably coinciding with the fireballs!

Two good nights in a row now. Caught a sporadic fireball and a handful of bright Perseids on Saturday night. Sunday night was even busier, with numerous negative magnitude Perseids. I visually observed two small Perseid fireballs, but the cameras managed to miss anything significant.

 

Have barely had a chance to get my breath back, let alone work on clips, and it's looking like we have another few clear nights starting tonight, but I'll get back here when I can, although it might be a bit of wait for clips!

 

Hope you and everyone else are having some luck with the clouds!

Glad you got some clear nights.  Had some clouds and rain here but not bad timing for me as my methods favor a moonless sky. 

 

It is clearing tonight.  I am planning to set up and maybe watch on and off for about an hour until moon rise.  I normally get up really early so it's going to be harder than it sounds to stay up past 11:30.  lol.gif

 

Luckily I am on vacation for a while starting Thursday specifically for the meteor shower.  Planning to venture out into darker skies for the peak.

 

Good luck and clear skies,

Eric

I am planning for the gemini shower later this year. is a tracker useful for meteor shots? I was thinking about stacking a few shots together for a more dramatic photo.

Trackers are very useful if you want to combine numerous meteor images into one image. 

 

There is a thread here with some great info you might find useful: https://www.cloudyni...er/?hl=+perseid

 

Also don't forget that you might have a good opportunity to do some testing over the next several nights as the Perseid meteor shower is currently active and is predicted to peak on Sunday morning.  I am hoping to use my tracker with one of my cameras to make a composite on peak night.  It depends on what the sky conditions are like if I will try that.

100% agree with Eric.

 

The trouble with having a static camera, is that as the sky in your initial FOV rotates out of the FOV, so meteors outside the initial FOV can't be used in a composite image if you want to be technically accurate/true to life. Tracking means you keep the same area of sky in the FOV, solving the problem.

 

One other thing I'd add is you could take a few longer exposures (stopped down if needed) once sky conditions are good/dark enough for the back ground image, but I'd suggest relatively short exposures the rest of the time (perhaps 15 or 20s if you can keep the time in between shots to less than 1.5 seconds or so, otherwise a bit longer would be better), with wide open aperture of course.

 

Definitely a good idea to do a practice run in the nights before peak if you can.

I finally managed to get time to sort out some clips of recent event the cameras caught. This first clip is of a sporadic with bright terminal flash that the camera caught through thinish cloud. Then a couple of nights back the cameras caught one with two bright bursts. Plenty of small negative magnitude Perseids also captured in recent nights but nothing that stands out.

 

Cloudy tonight and not looking great for the next week or so, but hopefully there will at least be a few gaps in the cloud around the peak nights.

Thanks, it just so happen, I am about to go on a trip near bortle 2-3 sky, definitely go to try this weekend. I had a look on Stellarium and stumbled upon a problem. There are going to be a lot of cursed starlink satellites coursing around the radiant point, I know they can be remove for DSO stacking but it doesn't work with meteor photos right? is there some way to remove/avoid them pre or post-process? do you just pick the photo where they are not in it?

Even without starlinks you are bound to catch a lot of satellite trails when trying for meteors.

 

For combing meteors into one image typically people will use a stacking method that will reject things like satellites (and meteors!) that only exist temporally.  Then will take the frames that do have meteors and add them back into the stacked image using a mask to only add the meteor.  It's typically a tedious manual process. 

 

My plan, which I haven't tested myself until I get data this weekend, is to use PixInsight to register and stack my frames.  Then I will identify any frames with meteors by manually reviewing them, and add them back in to my main stack using an inverted mask around the meteor and pixelmath.  I won't really know how well that works until I try. 

 

I will also likely be doing a lot more non-tracked individual exposures, which will result in usually just one meteor per image.  I like both kinds of images but this one is far simpler to process as you can imagine.

 

Good luck and clear skies,
Eric

It was a tough peak here once again. Very cloudy, but I did try running the cameras for a few hours although I don't think they caught anything significant.

 

Friday (night before predicted peak) was supposed to be almost completely clouded out, but turned out fairly clear in the end so I was able to run the cameras for most of the night. One camera did catch a bright Perseid: https://vimeo.com/854133211

 

Sunday night was of course also clouded out, and would have been another strong night, but I did run the cameras last night. Missed one nice fireball as I was setting up, and then the rest of the night seemed quiet... till I packed the cameras away (a little before light), and then of course the bright ones started to turn up again!

 

Still have a tonne of footage to check through in case I missed anything, but that may take some time. It's also looking clear tonight, so the cameras will be rolling again shortly.

Great catch, Leo.

 

Not sure if you saw, I started a thread here for the Perseid meteor shower: https://www.cloudyni...k-this-weekend/

 

I posted a number of meteor pics on page 3 of it.

 

I didn't catch my brilliant fireball directly with my camera but I did see an amazing one and was able to time-lapse a persistent train from it.

 

I have a video here on my youtube channel with that and other time-lapses and also slideshows of some of the better meteors I captured here:

 

https://youtu.be/Wp9WqeNj_4Q

 

If you look closely at the time-lapse at about 1:40 in the video you can see the sky light up from the fireball that caused the persistent train.

 

Clear skies,

Eric

I was out on Sunday and Monday evening, and saw quite a few, really chuffed with that. However, I only captured one on camera. I was tracking with my 24 f2.8 on a full-frame Nikon D3, aiming at the Perseus and Cassiopeia region but all the meteor seems to be appearing outside of my framefrown.gif . Any advice on framing? or was I just plain unlucky.

What settings were you using?  f/2.8 is kind of slow for meteors so it will only pick up the brighter ones.  I usually run my 28mm at f/1.4 and ISO 3200 with continuous 6 second exposures.

 

Framing is a bit of luck.  There are some optimal angles discussed earlier in this thread.  See this informative post from LeoUK: https://www.cloudyni...2#entry12700656
