Alien Space Craft in NGC 1333 Region?


vdb

Recommended Posts

Around a week ago I started imaging NGC 1333 under very bad conditions, the first tonights where around 50 images of 5 minutes, the 3 night I added 61 subs, there is something strange in the upper left corner going on which I can only explain by a very fast moving Alien space craft ... anyway the explanation is probably less shocking but none the less I want to know, anyone? I've been using this scope for years and never saw a reflection and the 10 hours of RGB data last year with another camera shows no trace ...

 

First 2 nights:

It is actually real phenomena, here is crop from latest processing from Rodd's effort on this target

OW! That is interesting it was not there last year!

Who is Rodd and where can I see the full image?

29/11 very few frames,

4/12 , 5/12, 6/12 40 frames

6/12 - 7/12 61 frames

How did you make that crop, I do not see it on the images posted, did you stretch it?

I just opened Rodd's last stack / processing posted, this one here:

https://stargazerslounge.com/uploads/monthly_2018_12/1715782770_Lum-Red711a.jpg.8e33384706866d6a8395e40a9eea3b6f.jpg

From this post:

https://stargazerslounge.com/topic/326424-ngc-1333-lumdone/?page=4&tab=comments#comment-3558237

This image is his latest attempt on stacking and stretching consisting of original 400+ lum with added Red channel - additional ~300 subs.

Given artifact could be from either earlier stack or from this latest recording of red channel

It was visible in other photographs on the web taken as far back as 2015 I believe...

Can you point it out in the image you linked there? I'm not able to see it.

Just checked first images in the post I referred to - there is no anything in lum only - it looks like it came from R channel addition.

It is however located above (or below) your two trails - almost like they are continuation.

Here is screen shot with markings:

It looks like you took images on consecutive nights as motion of the body can be seen - equal steps - length of trail is indicative of speed of object - we can measure it and divide with total imaging time stacked to get speed in arcseconds per hour.

Speed can give us upper bound on distance of object (can't go faster than speed of light :D, and probably much less - we can say about 30Km/s max for solar system body).

We can also measure width of trail to get rough idea of size of object (or whatever is making trail in images - coma of comet?) - very rough indeed - best estimate that we can do is to place it certain distance from earth, within solar system of course, but this lower bound will give idea of minimum size of trail.

I've aligned your two images and did max stack on those to combine into one image - here is crop, like I said it does match:

image.png.0832a64cdd2207282197592b5f8145dd.png

I guess we need for Rodd to post his red channel only fits without stretching so we can do some sort of calculations on speed. Size will not work - trail appears wide because of sigma clip - both of you used that algorithm in PI or similar and that is why it looks wide - in your normal stack it looks like regular trail of some object.

As you see in the none Sigma it is indeed a solid trail and there is even one more, but weaker!

Sorry, not seeing double trail - just one solid split into 3 sections - first night, and two times second night (maybe meridian flip was enough to create small gap in trajectory).

he means another object - probably an asteroid- on the right of the picture.  I'll check which one, just a second.

Oh, I see - there is bunch of them :D It is whole invasion fleet!!!

@vdb

It would be cool if you made animated gif - main trail is certainly bright enough to show on individual exposures.

Also, plate solving so we can have pixel scale and orientation could help us identify objects - above table can be used for comparison as it lists motion speeds along RA and DEC axis which we can use for comparison.

It actually looks more like Semiramis.

Image is aligned so that RA is close to horizontal and strongest trail has about 45 degrees tilt in trajectory. Only object that has similar values in RA and DEC speed is this one - similar speeds in DEC and RA will produce 45 degrees tilted trajectory.

It is also the longest of all trails in image - and Semiramis has the greatest overall speed on that list.

It has a pixel scale of about 0.934 arctic/pixel the setup is an FSQ 106 with the ASI 183, here the results:

 

Center (RA, Dec):(52.289, 31.385)

Center (RA, hms):03h 29m 09.372s

Center (Dec, dms):+31° 23' 05.396"

Size:83.8 x 57.2 arcmin

Radius:0.846 deg

Pixel scale:0.934 arcsec/pixel

Orientation:Up is 1.63 degrees E of N
