Canon EOS 750D - modified for astronomy.
ISO - 640
Lens Aperture 4.50
640 x 15 second subs
Cmos Temp seemed to stay at 15*c until the end although a lot colder outside.
Used APT and have paid for it as its brilliant.
Need help with the lines and dots
Roger
That's brilliant Roger, if there is nothing worth imaging DSO wise, why not do a star trail.
Good focus (presume you now have the Bahtinov mask) and good colour in the stars.
The dots top right are a plane's flashing light passing through the FOV.
Centre is a shooting star I think.
Bottom right a satellite probably coming in at the end of your imaging session, or going out at the beginning.
Good processing too, what did you use?
Carole
Actually correction, bottom right is another plane as you can see intermittent flashing lights there as well.
Carole
Thanks Carole,
Yes i thought they might be , but is that vertical splash of light under Polaris an Iridium Flare or is it a tad too long?
I just ran all 640 pictures through DSS on the settings Duncan recommended.
Roger
It could be an iridium flare.
Carole
Great first attempt Roger.
I'd definitely say and Iridium flare rather than a shooting star.
