APT

[Fay]

I am wondering if i did not bother with APT because it supports DSUSB & I have GPUSB. Anyone know if i am wrong?

Thanks

[Fay]

ok put wrong answer in here, so still need a any advice

[Mike]

What is your camera?

[Fay]

Canon 350D, and using GPUSB.

What is the difference between GPUSB & DSUSB?

[Mike]

As far as I know GPUSB is a mount guiding cable and DSUSB is a camera shutter control cable.

[Fay]

oh, ok Mike, so wonder if you have to have both?

Fay how many cables go to your camera ?

I have a micro USB plug that is for downloading the images and another small plug that goes in a round hole marked something like cable release.

You might actually have a DSUSB (or similar) because I don't think you can do long exposures without one

[Fay]

2, one for downloading pictures, the other serial to usb for shutter control

[mickw]

Sounds like you have the right cable whatever it's called  It's the shutter control one that APT needs for long exposures

You can download APT for free and give everything a try - It won't have all the bells and whistles but good enough for a test

normally fay there is a setting within the camera to change the camera from usb storage to computer interface.

if its set to mass storage you can download all your images as the camera appears as a hard disk (99%) of people normally use this setting
in the other setting you can control your camera remotly via the same usb cable.

the small 5mm hole is for a remote release.

when you press the remote release your camera will take a photo, if your speed is set to B then
the shutter will stay open for as long at you have the button pressed.

i am taking everything you are saying on board, thanks Mac

With APT you can control everything, after it's all plugged in the only time you touch the camera is when you do flats - you change camera back from "manual" to "auto"
