A very moody photo. Unfortunately - in my case, the moon also scrubs its belly on the horizon near this phase...

Moonkiller also does DSO occasionally.

 

This was only 37 minutes of integration at the wrong exposure. Still a cool galaxy:

M27. 4.3 hours at the right exposure this time, although it was pretty windy.

From few minutes ago. Wss imaging M12 and captured an interesting meteor in one of the frames.  This is cropped and reduced by 50 percent from original.  No darks or flats (with noise on this hot humid evening in Joshua Tree, CA.  A simple brightness applied, which shows the vignetting at the corners of the Panasonic Lumix full frame chip.  Taken with a Televue Renaissance 102mm f/8 brass refractor.  30 seconds at ISO 6400

Very interesting trail!! Does that mean it had an asymmetrical heterogeneous composition and was tumbling? Or was it "skipping" on the upper atmosphere? Or was it an orbiting satellite that was rotating? Or was it an incompetent UFO pilot executing a poor landing?

 

Hmmmm.  Can't wait to hear what Terra says about this one! As a Geologist I am sure she will have some insight.

Well, I'm a geologist, too!  But I've had a similar thought:  What if it's a tumbling satellite?  But it seems it would have to be tumbling rather rapidly for it to change brightness that radically.  But who knows?

I will note that last month, while I was looking for Neptunian satellites just before dawn, I must have had 4 or 5 satellites cross the narrow field while watching the live view.  Starlink, I suspect, as they were faint (but annoying).

I see a few trails in my astrophotos as well. Most are obvious and easy to explain; not like this one. I throw away about 1/4 of my exposures for one reason or another; many due to periodic error in my mount. One of the great advantages of our modern stacking technology is that such problems do not completely ruin our shots. In the bad old days of film, such a meteor track would be fatal to a half hour or longer exposure. Nowadays, it's just a little irritation... or an interesting conversation piece.

Even worse, from the film days, is guiding a 1/60th second exposure for an hour.  I've done that!

That’s a pretty typical satellite track for an object that is tumbling, usually a spent upper stage. Very cool. :)

I was at the Texas Star Party in the 1980's and shot an entire "roll" of exposures with no film in the camera. Those would have been world-class publishable shots!! I can laugh about it now after all these years. :-)

I had to laugh.....I have done that too!!!   Back in the film days we did not have auto guiders so it was much labor lost. )^8

 

I have also shot 4 hours of subs before I noticed I did not click the auto save button !   8^P

Here's an image of tonight's Moon taken with my Tasco 8V, Zwo asi224mc and Svbony 685nm Pass Filter all on a Celestron SE Mount.

22,000 images captured, best 10% used.

 

Clear skies

22,000 images... WOW! How long does it take to collect such huge amount of frames, and how long does it take to process them? I usually collect some 1,500 frames for the Moon - and it seems a huge challenge to my computer, especially if I try do apply 1,5x drizzle while stacking...

Hi, the video was 14 minutes long, 31Gb, 25k frames, 22k useable frames.

 

It actually didn't take too long to process, I had made Autostekkert AP boxes' size to 104 and no drizzle. In the summer, I generally do the stacking as I continue to do visual and can do the sharpening / post-processing after coming in

Te way that the brightness seems to smoothly modulate along the path, I would guess it’s a tumbling satellite.

Moonkiller. Click for Astrobin. Had to reduce by 50% because of some sensor tilt I have to tune out.
