    Default Couple more Comets



    Clear Sky Chart was a little behind last night, but it finally cleared off. Well, except for the muddy sky that has been an issue to the South. Darn 46P/Wirtanen has got me seeking out other unique stuff in the night sky. Found this site which is a real help in finding things, https://theskylive.com/ .

    Captured 46P again, the data isn't any better than what I already have so off to a couple new (to me) Comets. Captured both 64P/Swift-Gehrels and 38P/Stephan-Oterma. Data was less than 5 minutes for each image.

    38P/Stephan-Oterma
    121238PSWQIRC 2 RS by Brent Secord, on Flickr

    Both were processed (over) in the dark, late at night with RS6. Looked much better that way! ROFL Will take another run at them later....

    The above link also was Asteroid information. I either suck at spotting them, or have to change how I look for them.... ideas are welcome!

    Find reference sources for unique things is directly proportional to strength of your Google search abilities! LOL My search techniques suck. I am looking for something like Astrometry.net that will show Asteroids. I'll have to do a bit more research to find out if a paid license in SkyTools will do what I want.

    Thus far I've gotten away with using freeware stuff. It may show!!!

    The seeing was fantastic after the clouds took off, transparency was not so hot, The best FWHM I could get ranged from 4.5-5.0 and higher. The focus was done on a decent star, but the atmosphere messes with the FWHM, kind of like being out of focus. Bloated Stars are one of the indicators too. I'm no expert, and have a huge amount to learn. Nothing worse than seeing those stars twinkling away and you get a less than ideal image. (That's my excuse and I'm sticking to it, always blame the sky!!!!)

    Last night was a first for me too, had my very first wire snag!!! Probably had something to do with the wind at 25km/hr. The embarassing thing was the snag happened as I was doing my star alignment. I'm in the dark!

    "Hard to get", not especially. Normal 2 star alignment with 3 calibration stars. Pulled up the RA and Dec from the site mentioned above (in the tracking section) and went into the HC Utilities GoTo, plunked in the numbers and the scope slewed putting the Comet very close to the middle of the screen.

    I was just using the scope tracking, and these two are far enough away they don't trail as much as 46P. If I can catch 'em anyone can....

    Nice! Everyone should try to grab an image of 46P while they still can.

    Great captures, Brent. I can’t get over that you’re capturing these images with your Atik Infinity. Wonderful camera.
