Something moved during my night sky shot

Bigshot
Apprentice

Hello,

 

Screen Shot 2020-07-24 at 10.02.25 AM.pngI recently want to learn night photography of the sky. I had my first experience but the results were disappointing. I have a Canon 5D Mark IV with 24-105mm 4L Canon lens. Here are the settings for my photo. Manual mode, exposure 25 s, aperture F4.0, ISO Auto. When I examine my photo (below), I found that something was moving during this long exposure but I have no clue where to look and correct. Can someone help me out? Thanks in advance.

I noticed... I dropped the links and replaced them with uploads.  Which is just as well... I noticed some wonky JPEG compression artifacts on my comet photo when I view it on Flickr.  I don't see that on my local copy (but that may be the fault of my Lightroom export settings... I suppose I should double-check those.)

Looks pretty OK to me. Here is something to remember although it is night time and dark where you are, it is daytime on the places like the Moon and Jupiter and Saturn.

You can try a double exposure.  One for the stars and one for the 'whatever'. Then stack them in post.


Thank you.

Yes, it is daytime, but like the Moon, planets go through the same phases, it just takes longer. That is why it is important to shoot at "opposition" while the planets are full. The Moon on the other hand is sometimes better photo material when it isn't full. You get better crater detail near the terminator. And to catch the Moon during the day is even a bigger treat, at least to me. The moon with a blue sky background... Amazing! When I post full Moon images on various forums, I have throuble convinving people, mostly people new to it, that long exposures are not the way to go. I shoot it between 1/1000th and 1/2000th sec., depenting on how far the Moon is from the Earth, usually at ISO 400. Sure, you can go slower by adjusting your aperture, but I get great results with these two settings, so I don't even look at the aperture while shooting, but it's usually f/10ish in post.

 

As for stacking, I don't do it enough to warrant the $$ involved in getting a dedicated astrophotography stacking program or PS for that matter. My subjects and shooting style rarely require anything more powerful than DPP 4. I do have other RAW and image editors, but they are mostly for special effects and repair of a surprise "one shot only" gone bad, ususally happens when I have to instanly swing from the dark forest canopy to a bright open area and forget to adjust settings. Sometimes it happens so fast that I just don't have time to adjust, so I depend on post to rescue Smiley Happy

 

I've included some moon shots from the last "Super Moon" phases in May, 2020. All using the EOS 5D mark IV and EF 100-400mm L II, hand held, and heavily cropped. Please keep in mind that these are 1280 by xxx JPeG, so they look and print better as RAW. I know, sometimes I state the obvious Smiley LOL

This one has a story. I was laying on my back shooting circling Swallow-tailed Kites and waiting for one to fly in front of the Moon. Well, the Kites never did but I got this instead.

I've looked at several, but you have to convert to TIFF for the free versions. I just don't do it enough to bother with it. I've also found some that will use an AVI. The bottom line for me is you really need a tracking device or the time to align your images in PS or some other stacker, like Sequator. I've tried the "autoalign" feature in some, and it was marginal at best. Not owning PS, I can't comment, so just on the freeware.

Thank you, Sir! The right place at the right time, which is basically the story of my life. But I never tell anyone that... Ooops Smiley Surprised

 

This is what I was shooting. They have about a 4' wingspan and are just spectacular to watch. They migrate through and to our area in the spring and fall from South America. Late evening, so the lighting was tough to deal with, but that is why we do this Smiley Happy

Come to my house.  There's a Delta jet overhead about twice per minute (I live below the approach for the center runway for the main airport.). <sigh>

 

If there is *any* upside to this pandemic... it's that fewer planes are landing and departing and I can actually have a converstion on my back patio without being drowned out by the jets overhead every 20 seconds.

Smiley LOL I hear that! Fortunately, I live about 20 miles from Jacksonville International but still get low traffic to and from Miami and Orlando. Then to the west about 5 miles there is the Naval Air Station, but I am about 2 miles north of their normal flight path. Still we occasionally get fighters roaring over, helos, and the huge transports like the C-130 Hercules. I shoot them when I get a chance.

Most folks complain about airport noise. Funny thing about airports, and not to minimise your noisy conditions, but most time in today's airport construction they choose a place far away from populated areas. People than complain that the airport is too far or long of a drive to get to. Then housing construction and urban sprawl fills in around them. Then folks start to again complain about airport noise.
