No, but I use a 1/2" chromed ball bearing (amazon) in direct sunlight OR lit by a green laser pointer frequently.
And the Hubble Artificial Star device.
When I find where I put it I also use the excellent Hubble Optics 5 'star' (different apertures / intensities) Artificial Star with equal success. The astrozap-artificial-star never made the buy list once I got the excellent Hubble unit, and the chromed bearing also has been great.
Back stopping any artificial star with black paper eases things.if anyone tries the bearing, I found a cheap garden hose shutoff valve standing on end makes a perfect holder/stand.
Note that you cannot star test, Ala Suiter, unless you have a substantial distance with SCTs (false SA indications)but collimation has proven to be distance insensitive.
How close? I once got a very weird astigmatism on one side of focus while daytime collimating, and figured out I had accidentally set up at the near focus limit, distorting the primary as I went on the near side limit stressing the internal arm.
I no longer worry about collimating the SCTs at short distances.
I do check at night on Polaris but normally collimation is still good. Conditions permitting, and they often don't.
Tri Bahtinov and Duncan masks do well for coarser adjustments with artificial stars, too.
EDIT I was typing, and late to the thread as the OP ordered.You will like the freedom of artificial stars, and the Astrozap-artificial-star is a very good one.
