Canon 20Da

[Howellinone]

Downloaded the trial version and watched and the user video.....loving it! I have two cameras, the Canon 20Da and the Canon 60D. Here’s what I’m hoping for. The 60D connects flawlessly the 20Da as you can imagine does not. Seeings how the 20Da is modified there are certainly times I would love to use it....old camera but still does a great job. Here’s what I’ve done and gotten to try to make things work for the 20Da.

1) Purchased a Windows 7 32 bit laptop from eBay.

2) Purchased the DSUSB controller from Shoestring Astronomy.

When connected to Shoestrings DSUSB check app I am able to open and close the shutter and control other test parameters but BYE still won’t connect. Is there something I’m missing? I select the older camera option when prompted......any help appreciated!

Ill be using BYE either way!

You need to install the original Canon 20D drivers manually from the CD the camera came with, their drives are *not* included in Windows 7. This is required for Windows to see the camera.

You need both cable connected to the camera, the regular USB cable and the DSUSB cable. The DSUSB cable is *only* for BULB pictures, the regular cable is for connectivity and everything else.

Thanks for the quick response.....very much appreciated! I’ll search for the drivers but I seem to remember not having very much luck, Canon no longer provides them available.

Not sure what’s meant by “Both Cables” 
The three pin plugs into the camera from the control box, the control box plugs in the laptop USB....nothing else to plug in. Curious why I can control the camera shutter via the check app?
 

I must be missing something 🤔

both cables = the camera USB cable + DSUSB cable.

The check app (DSUSB cable) can only control the shutter, and nothing else. 

You need a regular USB cable connected from the camera to the computer in addition to the DSUSB cable.

I feel stupid.....The  N3  cable goes directly from the DSUSB box directly to the male N3 port on the camera body, the only vacant ports left are the video out and what’s labeled Digital.....no other available ports....I wanted to send a pic but exceeds the 500kb.
Im guessing it’s the DIGITAL port? 
Yikes........maybe more trouble than it’s worth.

Unfortunately, trying to use a Canon 20D for Astrophotography truly is "More Trouble Than It's Worth"...

1) Canon Drivers for the 20D are only available in the old WinXP 16/32-bit style which requires a TRUE 32-BIT Win7 or Win10 PC (not 32-bit Compatibility Mode in regular Win10 64-bit).

2) Canon Drivers for the 20D are NOT included in any supported Windows Deployment - you have to find the old Canon Utilities Disk

3) Canon 20D has no support for Live View - meaning best you can do is view short Snapshots for Framing and Focusing

 

If Time is Money, you'll likely Spend Less by picking up a decent Used Canon T3i or T5i (skip the T4i - Bad) and getting the Convenience of fully supported 64-bit Drivers INCLUDED in Win10 and Functional LiveView and single USB2 Cable control.
