Astrophotography

I do not know what is was, it did not move, the flashes were in the same position both times, very strange...
Both pictures were 30 second exposures, don't know if there are any stationary satellites in that area.

Iridium flares look like that:

yup exactly, often difficult to tell the difference to a meteor

Unless it is a bright one (this one was "only" magnitude -7.7) when it looks more like this:

What I caught did not move, any ideas of what it was?

Could be anything slow moving, a blimp, helicopter, high orbit satellite (depending on where you live even a geosynchronous satellite), etc.

If you know the date, time and location you can do a search here. Limit the search to say 10 degrees around RA 9h 32m, Dec +63deg40min and increase the magnitude cut-off as far as it will let you.

Thanks, I think it was the Chandra X-Ray Observatory that I seen.

Yes I am really happy I got it...my power supply to my laptop and mount was starting to drop so I got right at the end of the imaging session.

There was an Annular Solar eclipse path across part of Australia this morning ( Oz time)
I didnt travel for this one... I knew this one was coming up but kinda snuck up on me didnt realise it was going to be today till I heard a news item on the radio.

Fortunately I always carry my camera in the car ... tho I didnt have my big telephoto lens and I had to hurriedly make a solar filter out of one of those silver mylar survival blankets.

From my home area of Sydney City, SE coast of Australia, there was a reasonable chunk bitten out of the sun much like the Apple logo ;) of a partial eclipse.
Started at the upper left side of the sun and went anticlockwise around to the lower right of the sun where the moon finally left the solar disc.

I will post some pics when I get home tonite

As promised , a couple of pix :)

Pentax, K5, 55mm f/l, F10, 100 ISO, 2 layers of silver mylar across the front of the lens
The pix were ~ 20 - 30 minutes apart






now had i travelled to Queensland state, ~ 1400km to the nth of me I would have seen the sun looking like this....



This is a pic of an annular eclipse I took in Jan, 1991 from the city of Blenheim, at the top end of the South Island of New Zealand

cheers
