We had an unexpectedly good night in southern New England last night, and I split my first binary with my AT6Rc and Canon T1i.

I also got lucky last night and was able to split Rigel. The seeing was much better than anticipated.

You ready for this -

The other night I DREAMT I split Rigel with my reflector. Hit Betelgeuse.
Every once in a while I get an astronomy dream.

Optics are always collimated!

I have just been getting into double stars and such due to light pollution and the natural exploration of space. It's pretty neat seeing such a bright star with a very dim neighbor.

Rigel was always fun to split with refractors & reflectors of all sizes with various powers. In my 4" f/9.8 refractor at 125x Rigel splits very nicely.

Nice image, clear and crisp. For some reason I have always been able to split Rigel with slightly lower magnification. Perhaps it's due to the glare from the primary.

yes, me too. I found it to be an easy split last month at 88x. I looked at Rigel and it's faint companion to get a feel for how far the Pup would be from Siris, right now they are about the same distance apart. Rigel and companion were far and away much easier to see than the Pup and Siris. There is much less difference in the magnitude Rigel and it's companion.

Great image...thanks for sharing! I have been unsucessful splitting Rigel over my neighbor's house it with my 102mm refractor. But it was an easy split with the SCT.

There may be some heat convection over the house, a spot of poor seeing. I was able to see both components of this pair at 88x with my TV102. The companion to Rigel is very faint and can be easily overlooked or hid by convection curents.

Ack! Tonight I couldn't even get a hint of Rigel's companion in my 14", the seeing is so nasty. Sometimes, they show up as painfully sharp pinpoints with lots of space between them; tonight, zilch - one big hairy blob.

That's a nice image. I'm sure glad somebody is getting good seeing!

That's what I think too. I've been observing in the early evening lately, when Orion is still fairly low. I believe I would be able to split it if it was closer to the zenith, and not over their house.

Doesn't Rigel have 2 minor campanions?

I think I have an image I took several years ago with my 6"f/15..but I'm sure it has 2 companions. One extremely closer then the other. I could be wrong?

When I went to look it up, two different articles said that Rigel B was actually its own binary system, but was too close to be split visually by any telescope. Maybe the other one you saw was a background star, and not actually part of the system?

Rigel has 3 stars AB 0.13-10.4 9" , BC 10.4 10.4 0.1" and AD 0.13 15.3 43"

We will have to wait ions for BC :foreheadslap:

This is the image I took back in 06....

I might be wrong but I'm sure there are 3 stars in this system. I cropped the image to improve the image scale.

Would you be so kind as to label the A, B and C components in this system on your photograph, keeping in mind there Position Angle and seperations. If I assume that the closest star is B, then D isn't in the picture.

Checked 3 other references that indicate Rigel has only one visual companion. Recent observations seem to discount the early on observations of "B" being viewed as a tight .1" double.

You didnt image the 0.1" . Field star fill ins.

Itd be amazing to even a see an elongation. Nice shot though. Revealing.

AFTER further analysis..I concluded I posted the wrong image of Rigel...SORRY. I'm sure I caused confusion(I'm confused).

I'll search my images for it.

There are 3 stars, but Rigel B is far too close to split. If you're seeing more than that in your image, then one of them is a foreground or background star, and not part of the system.
