Hi All,
I have a quandary.....I'm hoping someone has seen before or can suggest something.
My normal capture laptop (Compaq NC6220C) is sick and keeps locking up with Stellarium running and randomly when capturing due to, I think, a stress crack in the motherboard which has to be kept under pressure by holding the case and pressing down.....
SO: I have put all my capture programs on to my work laptop (Hp EliteBook 8530P) with 128GB SSD Hard drive, Intel core 2 Duo, 4GB RAM Dual CPU....
BUT, when I capture from the DSLR, using the same cables, camera, powersupply, etc, I get monsterous amounts of USB or thermal
noise on the subs, even to the point of the bottom right hand corner looks like it has amp glow....??? Darks dont seem to be able to get rid of it either, which is quite strange....
I have tried every USB port for the DSLR connection, as well as removing the power jack and running on the Laptop's 10 hour extender battery and swapping cables etc, but its still there.
I suspect the laptop's USB2 ports are disgustingly noisy but dont know what I can do to alleviate the situation.
QUITE frustrating when you have a kick ass super speedy laptop thats stable, but makes your images look like a sunburned Englishman at Bondi on the first day of his holiday.....
I have posted a Fornax galaxy cluster sub (reduced to 200kb) as well as a single reduced 47TUC unguided 25 sec sub from the other night so you can see what I mean. Also, there is an Omega Cent sub (300secs at ISO800 at 13C, from the original Lappy, showing very little
noise.....)
Also, considering the ambient temp was only 7 deg C, the camera was hovering around 13-16C, maybe something else was causing the camera to heat up like a woman reading Fifty Shades of Grey?
Any ideas on what I can do? Quite frustrating, as I was loving seeing the Fornax cluster on the screen and took 15 x 3 mins shots at ISO 800, which are all quite rubbish now....
Cheers
