2 in 3 days only 3 degrees apart seems unusual to me, how far in real terms would 3 degrees be?

Here is an animation of Berts pics showing the faint Nova appearing. It isn't visible in the july 2006 pic (purplish one). Nova appears under the red dot, then dissappears in the earlier purplish image.

Ron, your field of view in your 20x80s will be between 3 and 4 degrees if that helps. To calculate more exactly, read off the bins - ???ft at 1000 yards (??? somewhere around 200?) and do some trigonometry. Orion's belt is a good real test - see how much of the belt you get into your field of view and look up the spacings.

Perhaps you meant, how far (in light years) between the two nova. That is a question for the professional astronomers!

I'll try that tonight if I get a hole in the clouds

Hehehehehe I'm glad you took the time to answer, it doesn't mater that your answer was to a different question

Just getting back to the original point, in astronomical terms, what seems close to us, may in fact be a very long distance apart if one of the Nova is close (in the foreground) and the other is larger (further back in the background), if we are seeing them head on, we sense them as close but they may be a very long way apart.

The angular distance may be only a few degrees, but the distance from one to the other could be enormous. One could be close to us and the other could be faaaarrrrr from us, making them not even close to each other.

EDIT: Oops, sorry Ron, you just said that!

Spotters Map

G'Day All

UPDATE: I messed up the location of V1280 on the maps. This time I did the right thing by adding the novae location via SkyMaps quick catalog feature.

I've made a replacement spotters map (roughly the field of view of 10x50 binoculars) which you can download from
http://photos1.blogger.com/x/blogger...t_26-02-07.jpg
I've attached a reduced size version of the correct chart to this message. Latest reports put the new nova at around magnitude 6, up from around 8 before. It may brighten more or just fade away, but I'll have a look this morning.

Updated 26/02/07 It is back down to magnitude 9.0.

The first image is both novae in Scorpio taken 26-02-2007 at 4AM+. Second image is from the 18-02-07 at 4AM. Third is the same field from image one. As Max would say, missed by that much!

Here is an image with both novae marked with a line below them.

The images look great! I got up at 4:30 to have a look with binoculars, saw nothing down to magnitude 8. I feel a lot btter now knowing someone imaged it successfully.

It's been raining in Sydney for the last couple of days, but hopefully soon I might get the chance to take a peek. This latest image pretty well says it all, as far as I am concerned, they are almost next door neighbours

Here is a higher resolution image of both novae. The FOV is 6.8x4.6 degrees.
