For what it’s worth I’d ask Dave Kriege what he puts on his UC line. I have his UC22. What he used looks similar to Ebony Star in both color and surface.?

All,

Found the Swan Nebula M17 in the gap of my trees over my neighbor's house.

My UC18 + DS10cTEC + LeNhance filter with ServoCAT tracking found M16 in the gap of my trees over the neighbor's house.


Richard

All,

Having fun with my:

UC18
LeNhance filter
DS10cTEC
ServoCAT

Need a tree guy to take out a few Oak trees to my south.

Ebony Stat was just the color. it was the '50' finish that made it work, and apparently, the -50 finish is not offered anymore. Read this...



... and this...



... and you may find your answer!

The UC18 + ServoCAT + DS10cTEC + LeNhance filter enables astrophotography.

Here is the Eastern Veil Nebula NGC 6962.



Richard

Don't do what I did and try to image near the zenith.? The ServoCAT tracking is a bit jerky near the zenith.? If you get 5 or so degrees away from the zenith the ServoCAT tracking really improves.

This image has wonky stars, but the nebula is awesome due to the way the Mallincam Sky software stacks.



Richard

UC18 + DS10cTEC + ServoCAT + LeNhance filter + 250 second exposure.

Hi Richard, nice picture and you got the diffraction spikes of JWST, classy :-) Frédéric

All,

The SunFlower galaxy is a fun target for the UC18 and DS10cTEC camera.



Gota love galaxy season.

Richard

Thank you for the replies.

I remember my eyebolts being bigger than 1/4". So I pulled the scope out of storage and measured them. For those interested in Obsession minutia, the eybolts on my classic 25" #236:

3/8-16. over all length 5", threaded 3"

McMaster carr has lots of eyebolts that match. For example: 3014T143

clear skies.

You should be able to find one at McMaster Carr.

I have a 2006 25” and replaced 2 of mine from Home Depot with eye bolts. ?I can’t remember but it may be this. It took a few tries. ?

Anyone know the thread pitch and diameter of the eyebolts used by the wheelbarrow handles on a classic 25" obsession?

Thanks very much for sharing. My new 15 UC just arrived and the digital copy of the manual is appreciated. Tom

Hi Richard, and everyone who made helpful suggestions.? First I increased the Alt axis limit from 60 to 80 and transferred this updated file in the configuration program to the scope. Then I've just performed some daylight "GOTO" tests using my mobile phone strapped to the central truss and with the Stellarium app running. After a virtual 2-star alignment (not a perfect score), I then performed some GOTO commands to various objects involving clockwise and anti-clockwise azimuth slews and up and down altitude slews. And bingo the problem now seems to be resolved, GOTO gets to where it is sent without the need to press the GOTO button repeatedly.? I noticed that the meter reached a maximum of around 2A on the power supply when the scope was at full GOTO speed.? I think before it never went much above 1A.?

I won't tinker any more for the moment and see how the scope works in a real night-time session.

Thanks again!

Cheers,
Mike
