Ballard Loc: Grass Valley, California
 
This is one of the 30 second luminance subframes I took the other night. In this 30 second period there where 16 objects moving through the field of view. Virtually every subframe that I took contained a few of these intruders. In general, these objects are fairly easy to filter out, except for the really bright ones that may need some hand correction after stacking. This particular subframe stood out due to the variety and number of objects flying though the field of view (With the 500mm lens the field of view is 4 degrees 7 minutes wide and 2 degrees 45 minutes high). ~All the objects have circles showing where they are. In a few cases there where several in close formation. Double download will be necessary to see the separate trails. The brightest one appears to have some type of trail behind it, so it probably was a very very high flying aircraft of some type (note: blinking running lights would not normally leave a solid trail so this was probably reflected sunlight which would have to have been extremely high up at the time of this photo at 9:22 PM PST on Nov28 > 4 hours after sunset).

Seems like I'm living under a flight path of some sorts, but you must be at the end of the runway. The weird trail might be somebody opened the black tank over you. I'd inspect my lenses and mirrors for undesirable coatings...🥸🥸🥸

Hi alberio

Thanks for the comment. It seems that Orion is in the path of many satellites, I guess it makes sense since it is close to the celestial equator. Fortunately, no undesirable coatings where found. (A few birds have tried to purchase the telescope cover as they left deposits on it).

And they want to put more up there!
Trouble is, we are a very small minority who are bothered by these working and dead space garbage.
Orion has a 5 satellite squadron crossing it.
I'm convinced they put them up to scare away the UFO's.

Hi SonnyE
They are a pain in the butt to clean out of deep sky photos. Supposedly the new ones that they will be sending up are less reflective but that won't help with the garbage that is already there.

I do think they do dwell among us. Just look at all the space cadets we have here on the hog.....

Hi Hal81
Thanks for the comment. Sometimes I feel like one of the space cadets.

All of the airplanes I've recorded leave very distinctive trails with red, green, and white marker lights.
The satellite's, just white streaks because they are reflection the Sun off their surfaces.
My theory on the dotted lines are satellite's that are rotating so they appear to be blinking. All I know for sure is they are a blinking pain in the rear.
It's not enough we have the atmosphere throwing clouds at us, but now all these satellites too.

Yall might think they're all satellites but, after watching a barrage of streaks in my subs {I think we're being watched}. It's peculiar that the sightings have increased.

Could be. In the early evening in 1981 I watched a satellite coming out of the earth’s terminator (going from east to the west), at the same time I saw another one going from the west to the east at about the same brightness and velocity. As they crossed by each other the one going from the west to the east did an abrupt U turn and got behind the one going from the east to the west. This U turn was.completed in 1 second or less. In low earth orbit they would have a velocity on 17500 mph. To make a U turn would require a velocity change of 35000mph. To do this in 1 second would require an acceleration of ~1600 G’s.

It never amazes me , I can't go into detail. I will say it's coming Ballard and we can't stop it.

Stellarium Web is a fun observing derivative of Stellarium.

https://stellarium-web.org/p/observations

I was trying to make the satellites show better and found if you scroll in (zoom in) on the view (I use my mouse wheel) the satellites pop out of the background.
I know of no way to remove them effectively from our images. But I expect some enterprising geek will develop a way for the more popular processing software.

Personally, I ignore them or if I have some truly obnoxious streaks, or airplanes, I just delete the image before stacking.
There are trains of them running around, too. Satellites.

My currant settings are to collect 300 second exposures (5 minutes) X 20 each. I'm doing LRGB one night, then HA, SII, and OIII the next on a particular object.
I've finally gotten my meridian flips to work! Last night I was about at zero time and trying to watch without sticking my fingers in it. I woke up about 25-30 minutes later and couldn't tell.
So I finally went out back and sure enough, the entire meridian flip had done, and the telescope was ready to finish the night. It was done, centered, guiding, and collecting images.
Pleased, I headed for bed. When I looked out this morning, the telescope was parked, and I had my subject completed.
I slept through the flip, and slept through the rest of the collecting.
I think I've arrived. I just don't know at what station....

Hi SonnyE
With pixinsight you can remove satellites from the image while stacking. My understanding is that the code compares each image and if the some of pixels in one frame show a big difference from the mean of the other images, it won't use those pixels from that image, but still uses the rest of the image. You can adjust the high and low filters that do this to remove all but the brightest satellites.

The included image is an example of what the high rejection filter removed from the stack of images using this method.
