Subject: Re: [Astro_IIDC] First image light with 18" ultralite dob

Thanks Ron & Milton,

The whole setup is homemade .... just not entirely by me!  The previous owner/maker followed the Obsession ultralite design very closely and the price was so good that I couldn't have built it myself for the price.  Comes with Steve Swayze optics to boot.  I did, however, make the motorized base which allows me to track and fine motion control the dob necessary for planetary imaging.

regards,

Jim

Hi Jim;

Very nice looking big scope.

Did you make it or buy it?

And how much does it weight?

Thanks for sharing..

Well, actually second image light since I did try some monochrome imaging the night before and realized I needed to chop off four inches from the truss poles to create enough focus travel room for a filter wheel and powered focuser.

Here's Jupiter at around f/15 under medicore seeing:

Here's what the dob looks like this morning:

Can't wait for some real Spring weather and hopefully better skies!
