Simple question here -- on the CP3 box I assume the 12V power accepts a 2.1x5.5 center positive 12 volt cable - correct? I would like to just use a Powerpole cable I have here vs the cig plug one.

That is really nice to hear.

Thanks,

Superb Rolando,the Mach2 is really made to relieve us of the guide.
I tested the 2nd evening for my Mach2 after a 35 point modeling of the 600 "poses on M109 ... with round stars as I had rarely succeeded with guide.

We have one more obscure bug to fix, and Liam and I have to finish the keypad instructions.

Excellent!

Looking forward to the release of the new keypad software.

Hi Rolando,
   That's an interesting technique. I usually use 5 min subs. I'll try it out the next time.

10 minute subs x 12

I like to expose until the central part of the galaxy is near saturation, but does not exceed it. That way the core is not blown out and no detail is lost there.

how long was each exposure?

Hi Astronuts,

I joined AstroBin and posted my first image. Hope the link works:

This is an image taken with the Mach2 and 160EDF refractor, unguided over a period of 2 hours. I modeled a path that the object would take with 3 data points and let MaximDL take a set of images until the scope ran out of room and stopped at the limit. I'm shooting in very light polluted skies, the Moon was up and bright, so i was pleased that i was able to record some very faint stuff.

No guide scope was used, no field flattener, just the 160 refractor straight to the 8300 chip. Larger chips would need a flattener of course.

De-Oxit can be purchased through Amazon or you can find it in local electronic supply stores.   I have been told that music stores that sell musical instruments stock it for bands.

Dean, tell me about DEoxit and where best to get it. I use an automotive terminal cleaner, not for battery cables that I’ve used in my dads auto shop years ago, may not be best for finer electronic boards. Tom

Yes, that was the problem.  Cleaned the blue board connector and pins with Deoxit and it boots right up.  Now to change the battery while I have the keypad open.

Hi George

Would you recommend using a dielectric grease on these connections to minimize / prevent corrosion ?

I have never seen any corrosion on my keypad or mount cables, but I have seen some corrosion on the USB cables that plug into my cameras.
