webcam doubles

[nytecam]

Did some wide doubles last week via a National Geographic magazine cam/webcam that came free with a sub awhile back. I removed the cam lens and just Bluetacked a EP adapter to couple it to my scope. Supplied USB lead couples cam to laptop for some avi vids or snapshots as here in Albireo, beta Lyr, alpha Her on Double-Double pic. Scope current efl ~1200mm so scale too small for later pairs eg unresolved but elongated. Faintest star recorded = mag 9.4 in frame rate/ exp ~0.2sec.

Took a little time to rotate/ orientate cam so E-W was horizontal in pics so PA measureable but not sorted image scale for 'separation'. Anyone tried this approach?

Florent Losse's program is very good!

Yes Ken - I contributed to that discussion too and many [harware] issues therein remained unanswered. My NatGeoCam conversion proved the simplest yet and may get more into imaging. What are your thoughts of dealing with a webcam's aggressive contrast with single small object [planet/star] against dark fov and fooling the AGC by fogging fov with weak LED[?] illumination ?

Hmmm

Could an IR source be used?

This could maintain a reasonable SNR in the visual??

...or maybe ask your council to install more Na D lighting so you get an orange background to fool the AGC....
