Re: [Utah-astronomy] Observing Report from the Gravel Pit
I did it with an OIII filter but I think that is cheating. Seeing has to be superb to get a clean split. Debbie
I have split Antares many times with a 5" Refractor (APO), 8.5" Ceravalo and 18" Starmaster. The key is to do it early in the evening before it gets too dark. You also need a good location with steady seeing. Wolf Creek would be great. Kim, are you still going to Wolf Creek Wednesday night. It looks like we have a much better chance for good weather Wed. night-Thurs. morning than we do for the weekend. Clear Skies Don Colton
I'm still planning on Wolf Creek Wednesday - hope to arrive before dark.

Not cheating at all, Debbie. Whatever works. Little known fact: Right after sundown there is often a period of excellent seeing, before the ground starts re-radiating heat absorbed during the day. Sometimes it lasts for about 40 minutes but 20 is more common. This phenomenon allowed me to get some incredibly sharp video of the SL-9 impacts with Jupiter. I was hoping to take advantage of this, plus a "bright" sky to suppress the primary. But last night it was not to be. I found Antares just east of the meridian and followed it through until well after dark and it began sinking. Seeing was terrible, turbulent. Most unsettled diffraction pattern I've ever seen. Next time. --- UTAHDEB@aol.com wrote:
