Long Exposure settings for SPC900NC??

[pritc]

Hi to all,

Help required please....

I have recently done the SC1 mod for one of my SPC900NC webcams but I need help on long exposure settings for Deep Sky captures.

I have been using Sharpcap and a unmodded SPC900NC for lunar and planetary images with great results.

As Sharpcap does not seem to have long exposure settings I have turned to Astrocapture for DS imaging.

I have wasted a lot of time trying to capture M13,without success:(

Can anyone help me the basic settings to get me started??

You need a different capture software as SharpCap doesn't support LX.

The best one is..... something I can't recall the name of but it begins with a W! On the mobile so can't check at the mo.

wxAstroCapture. Great program.

I've had a play with my SC1 modded webcam and wxAstroCapture, (had an LX signal problem but a kind forum member helped me out) but haven't tried any proper targets.

That's the baby!

Hopefully have my LX modded cam back in the next couple of days. Roll on clear nights!

Had a go at M57 tonight, still no joy....

How did you know you had a LX signal problem??

Was your parallel port not set up correctly??

With the help of another forum member, we located the problem. It was stupid really, I forgot to cut off two pins on the camera plug board... It was my second attempt at the SC1 mod (the first I stamped on with my DMs, as it wasn't going very well AT ALL!! )

The camera initially worked as the default webcam - but when switched to LX, there was no visible difference of the image brightening at intervals. Using wxAstrocapture, I tested this at 5fps.

When the camera was eventually correctly completed, the LX switch enabled the resulting image to brighten at intervals.

I will stick at doing planets at the moment, but there's a possiblity I will be acquiring an EQ mount at some time in the future.

You can always test by putting the camera in a shoe box with some print (newspaper, book etc) at the other end. Cover well to exclude light leaks and then focus until you can read the print clearly.
