Hi Milton, 

The first link below(CGEM) is the best & I`ve bookmarked it to go in my Spaces window. I hope it stays current for a while a least. The NexStar HC extension cable also on the page is also interesting as trying to leave mine briefly on the accessory shelf is a recipe for mistakes.

I also have a F-C mount adapter in the mail to attach Nikon lenses to my CCD`s. Will perhaps post a picture from the garden taken with the Flea 2 when this arrives..

Thanks,

Mark.

Hi Milton,

Have you thought of providing more detailed drift alignment directions  

in Astro IIDC?

No. There a hundreds of links on how to do this online.

I realise you have "Analyse RA/DEC Tracking" which  

provides the reticle needed & Astro IIDC already has the ability to  

bin images so stars become more obvious. The proceedure of drift  

aligning is not clear however from the instructions I`ve seen in the  

Manual.

Actually, we do not describe how to do drift alignment in the manual. The only reference in the entire manual to "drift align" is on page 92 of the manual, as quoted below:

- The "Reticule Cross Hairs" and "RA/DEC Tracking…" features can also be used with Drift  Alignment to accurately polar align your equatorial mount. Their are numerous articles available  on line describing how to do drift alignment and you can find them with the keywords "drift  alignment" in basically any web search engine such as Google or Yahoo.

So use Google or Yahoo or whatever search engine and search with the phrase "drift align" and follow the instructions. I found 50+ in a few seconds.
