Free 3 month upgrade to the first person who can correctly answer all of this... *Congrats Dr. Acula!*

4-arm Spider diffraction and possible apodization.

what the thing the telescope is pointed at... i have no clue.

And so many stars.. they appear to be lines of similar star images, almost as if someone took a few exposures while kicking the tripod.

oh heavens no... you'll prolly beat me lol lol

i've learned some things in any measure

Strehl ratio degradation caused be a spider diffraction!

im not saying thats right?! but....
find the plate number! lol lol

I need a break. I'm reading way too much stuff using terms I'm not familiar with at all. Getting a headache, but I'm not giving up.

yesh yesh take a break... take all the time you need away


muhwahahahahaha

lol

:watdafuk:

Wow...AC you are correct!! Good job!! Just need to figure out the #??

The Attacking Space Spider. This is one of many internal reflections caused by a nearby bright star. It’s a silhouette of the outline of the diagonal mirror and its holder (called a ‘spider’) inside the telescope.

looks like we have our WINNER AC 33011729


and ya know what's weird i thought for a moment that looked familiar to what i've noticed in a telescope....but that was a good.....ANOTHER ANOTHER!!!!

Where's the Doc?

ASTRO!!! come hither!

Allow me to clarify, there is a proper name for the thing that is causing it. Not just a name for the phenomenon in general, that's just what it is, but additionally there is a proper name for the thing that is causing it to happen in this specific case. Ideally you should have to find and refer to the original source material to confirm that part of the answer.

LOL!! I'm glad somebody solved it. I can now stop researching!!

She has half the answer. I'm still waiting for the other half for a completely correct answer. What is specifically causing it in this case, the proper name. The spider vane is just what it is, but the presence of the spider vane alone does not cause it nor is it necessary for this kind reflection to occur (my telescope lacks a spider vane and still experiences these kinds of reflections). What is causing it in this specific case, and yes, I'm looking for a proper and specific name. It requires knowing where this image is pointed.

Tell you what, I'll go ahead and give the big hint now. This will very easily lead to the answer of the specific name of what is causing this reflection, so I want all three parts and I will give 3 months of upgrade. You have the first part, it's a reflection of the telescope's optical train with the spider vane prominently visible in the reflection. What is the proper name of the thing causing it to happen, and what is the identifier of the film plate?

As difficult as that sounds, it's actually fairly easy with this hint:

You might find that link handy...

For some reason I can't see the actual images. Photoshop or picture viewer doesn't recognize the format...

These are plate numbers from the right time though.

damn :)

A) I want to learn.
B) If we match the image, then it's truth.
C) Same as B.

3rd dimension twilight zone

the moon is causing it!!!

Well, this is where to find it... Right near canis major

Center (RA, Dec): (105.947, -19.568)
Center (RA, hms): 07h 03m 47.386s
Center (Dec, dms): -19° 34' 03.932"
Size: 59.9 x 60 arcmin
Radius: 0.707 deg
Pixel scale: 3.52 arcsec/pixel
Orientation: Up is 180 degrees E of N

Lets all get 'serious' about this!

This has been a lot of fun even though I'm not good at guessing it.
