Hi all..

 

I'm new to the world of Astronomy / AP.. But I think I saw something cool..

 

I have a Nexstar 8SE, with a f/6.3 focal reducer, and Nikon D5300.. 

 

 

And I was idly watching Betelgeuse last night, testing out the camera - when I saw big bursts on about 20 of my photos.. And then nothing in the next 128 subs I took..

 

Taken with exposure time of 1.5sec, and ISO 800..

 

 

Could someone tell me if I'm witnessing a huge electromagnetic burst of energy from a star about to go supernova.. Or just a peculiarity in the optics?

 

 

I've attached a little extra bit of the photo so you can see some other stars for comparison..

 

 

Thanks!

(a mystified) Carl

 

 

PS.. Lens flare or not.. It's still going on the wall!

Internal reflection in your scope

That's a reflection from the front corrector and the secondary holder. How much of this effect you have will depend upon the brightness of the star and its position within the field of the camera/scope.

Definitely a reflection from your equipment.  Betelguese is too far away to be able to see something like that.

This is the shape of reflections from stars that are near the edge of the rear baffle diameter.  It becomes more obvious visually with bright stars with 2" set ups or when reducer/correctors are employed.

Thankyou all for the clarification.. Shame really, I was just about to write to 'Nature' and tell them the supernova started..

If it were, it would be a loop prominamce and it would be epic considering the relative size to Big B, as I call it, cool looking none the less.
