Then one day, you find yourself with a top-notch stereo and a whole new world unfolds. That's how I feel after spending an hour or so tonight under some unbelievably dark skies out at Linda's folks' place. We pulled in just after dusk and it was http://www.lannuier.com/astro/ea/2008/10/observing-tv85-at-whiskey-hill.cfmnoreply@blogger.com (Paul)tag:blogger.com,1999:blog-5458264.post-7251633767064728545Sat, 11 Oct 2008 07:25:00 +00002008-10-11T07:47:29.770ZChecked the 40D + MaxView DSLR rig on the Antares 127mm again, this time with the TV32mm Plossl just to see if my focusing problem is caused by the Celestron eyepiece. It isn't - the same deal. I'm wondering if it isn't as simple as a field-flatness issue with the Antares that might be corrected with a add-on field flattener. Next time: TV85. I packed in the 40D and broke out the DSI for the http://www.lannuier.com/astro/ea/2008/10/observing-imaging-moon-jupiter-with-dsi.cfmnoreply@blogger.com (Paul)tag:blogger.com,1999:blog-5458264.post-5152391350356464465Thu, 09 Oct 2008 03:40:00 +00002008-10-09T23:24:59.609ZFirst time out with the Antares 127mm since I upgraded the focuser to the GSO Crayford. A 9-day old waxing gibbous Moon was the target, and the scope did a fine job with the Minus-V filter in place. So nice, in fact, that I decided to grab the camera and see whether the new focuser helped with the focusing problem I had last time I tried to do some imaging. Alas, it did not - once again every http://www.lannuier.com/astro/ea/2008/10/observing-moon-jupiter.cfmnoreply@blogger.com (Paul)tag:blogger.com,1999:blog-5458264.post-3675679414285053574Wed, 08 Oct 2008 20:36:00 +00002008-10-08T21:09:12.751ZJust after I purchased the Sirius mount, Orion upgraded the SynScan hand controller. Among other things, the new HC allows firmware updates via the net, and has improved tracking and fine-tuning of Go-To objects. Sounds like a worthwhile upgrade, so I emailed Orion customer service a few days ago to find out what the upgrade path is for an existing Sirius owner.

Been a while since I used this mount but it went pretty easily without me having to dig out the manual - good thing, too, because I have no idea where that is. At around 9pm it was just dark enough to see Polaris through the polar alignment scope.

Worth to the north and Austin to the south. My house is in a fairly new development of duplexes and town houses (so new that in Google Maps, it's shown as an empty field).

The new abode is just south of Waco and barely 1/2-mile off I-35 so the sky is fairly soupy. Still, at zenith it is just a bit worse than Lake Wallkill - I can see Milky Way through Cygnus and M31 is faint naked-eye. The big trade-off is the trees: there ain't none here!

Lost time is a popular topic in science fiction and UFOlogy, but my lost year is much easier to explain: damn near all of my free time for the past year (longer, actually) was spent renovating a house in Closter, NJ that, in the end, I never moved into.

Stark Labs has Mac OS X software that will work with the DSI - Nebulosity for imaging, and PHD for guiding - so this should prove interesting. PHD will work with the NexImage as well, I think.

Once again I was awed by the TV85; not a hint of color at the edge where the bright moon met black space. There was little turbulence and the scope just snapped into focus, even at 115x with all the touchy-shakies.

Tried something different this time: I chose 3-star alignment, then tweaked the mount's RA & dec to center on the first star (Altair), then completed alignment with Vega and Arcturus. Not perfect, but it it puts M29, M27 and M57 in the FOV of my LVW13! Beats the hell out of the so-called polar alignment scope which is a joke.

I'm happy to report that M29 is still there. I didn't stay out long, conditions weren't that great and humidity was getting bad. I had all of the gear in storage at the Closter house, brought it all back to Lake Wallkill today with the intention of finally equipping the Antares 127 with the http://www.lannuier.com/astro/ea/2007/08/observing-back-in-saddle.cfmnoreply@blogger.com (Paul)tag:blogger.com,1999:blog-5458264.post-2035445652932906096Sun, 15 Apr 2007 15:13:00 +00002007-04-15T15:22:25.447ZThis is amazing. From Joel Hartman (Harvard-Smithsonian Center for Astrophysics): "RR Lyrae often have amplitudes of variation as high as 1 magnitude in V, and even higher in B. The RRab stars (fundamental mode pulsators) are the most numerous and have periods of roughly half a day. The RRc stars (first overtone pulsators) have periods of roughly a third of a day.

However I have been stepping outside for short bursts to gaze upon the winter constellations (Orion, Auriga, Gemini) naked-eye from the deck.

Moon rings are caused by moonlight being refracted by ice crystals in the upper atmosphere. Photo taken handheld, Canon Digital Rebel (300D), ISO 1600, 1/2-sec exposure, 18-55mm EFS lens (@ 18mm, barely wide enough to capture the entire ring!).

I'm not too pleased, frankly. There are paint chips all over it and a good sized gash on one of the panels; it looks as though it is a repacked factory second unit.

To remedy this weak link, I ordered a new FRM2 dual-speed Crayford focuser from ScopeStuff for $149.00; mounting it to the Antares required the FRC7 5" adapter ring, an http://www.lannuier.com/astro/ea/2006/09/antares-127mm-crayford-upgrade.cfmnoreply@blogger.com (Paul)tag:blogger.com,1999:blog-5458264.post-115893250062417850Thu, 21 Sep 2006 22:30:00 +00002006-09-24T14:58:41.276ZNew moon Thursday night, cool and clear. It's TV85 time, because I don't feel like doing the big-scope setup and breakdown thing on a weeknight. It was dark already by 8:30pm, temp 51 deg, humidity 91% with dewpoint at 48 deg, so I thought it prudent to break out the dew zapper for the objective - I never got the heating element for eypieces but it seems to be OK as long as I keep the lens cappedhttp://www.lannuier.com/astro/ea/2006/09/observing-clusters-galaxies-in-and-tri.cfmnoreply@blogger.com (Paul)tag:blogger.com,1999:blog-5458264.post-115723391758552221Sat, 02 Sep 2006 21:33:00 +00002006-09-03T00:13:03.203ZI received my Version 6 upgrade to Starry Night this week - spent the extra dough to move up from Pro to Pro Plus, which includes the AllSky images.
