What is this Blue Object??????

[Striker (Tony)]

Hi All...

Just wondering what this blue image is right beside the star Formalhaut out of focus.

I think this focus shot was taken 2 night ago.

[ballaratdragons (Ken)]

Looks like Neptune! I'll have to check Cartes Du Ciel.
If it is, it is a nice clear pic of it!!

[ving (David)]

nfi tony... looks like a planetary. have to check it out.

[ballaratdragons (Ken)]

According to Cartes Du Ciel it appears to be the Star 18 Epsilon PsA.

[PhotonCollector (Paul)]

I don't think Uranus would stray that far from the ecliptic.
It's looks like Fomalhaut's companion star that I use to get good focus.

What Field of View is the image ?

[ballaratdragons (Ken)]

Both Uranus & Neptune are nearby but not that close. It would have to be a very wide angle shot to get either of them in.

EDIT: My mistake, it is the Star HR 8740

[Striker (Tony)]

FOV...haha as if I would know.....lol

was taken with my C11 at 1900 Focal length with canon 20DA sct prime focus....

So what ever that adds up too...lol

This is an uncropped image so it show's the full FOV through the Canon

The thing is I took another shot last night before the clouds moved in again and it was much higher but in a northerly position instead of S/East as per the original image.

[ballaratdragons (Ken)]

Tony, if the Blue object has moved then it must be Neptune and the bright star is '23 Theta Capricornus'.

That's the best I can work out.

[Striker (Tony)]

But the planets dont go anywhere near Formalhaut...

Here is last night focus pics before the clouds come in.

On second thoughts, i think that it may be internal reflection of a very bright object caught by the camera. i take it the images that you took were of different lengths in seconds. the longer the exposure the brighter the object, and slightly offset from centre the greater the chance of getting it (maybe)

[Striker (Tony)]

Hmmmmm

Still not convinced.

I say I discovered something....but dont know what...lol...well I wish

[ving (David)]

is there a comet in the area?

Simple, take a few images tonight of the same area, and see if we can also take some pictures of it and all see what we get. (we have clouds and storms forcast tonight but I will see what I can do) Can anyone provide a picture of this area of sky?

[Striker (Tony)]

I will try but storms are predicted every night this week.

But if I get peak through some clouds I will take another picture.

[Xeelee (Chris)]

Mmmmmm, storms, good for rain and the odd cool day not much else unfortunately

[acropolite (Phil)]

Had a good look at SNP and the star pattern around both Neptune & Uranus isn't really recognisable on your image so maybe you have discovered something Tony, Too big an area to be hot pixels and in the wrong place as well. It's moving so it can't be a star. If you get a shot at it again can you post the RA and Dec so we can have a look.

[atalas]

Its got to be an Asteroid Tony ! check them for the nights you took the shots .

It's a space ship!
