Autoguider use
by Chuck Hards 08 Apr '11

08 Apr '11

I'm curious as to what the seasoned imagers on the list use when selecting a guide star, specifically, swapping an eyepiece parfocal with the autoguider, or a flip-mirror? I'm also guessing that Newtonian users don't have the back-focus to use the flip mirror. Thanks!

Re: [Utah-astronomy] Galaxy hunting CDS-Simbad shows two journal references: http://cdsportal.u-strasbg.fr/#MCG+01-48-001 Click on the link "2-bibliographic references". Only one of the links provides any substantive information - that the galaxy is odd because it is within 5 degrees of the galactic plane: 1995A&AS..110..269W Astron. Astrophys., Suppl. Ser., 110, 269-277 (1995) Penetrating the "zone of avoidance". I. A compilation of optically identified extragalactic objects within |b|<=5deg. WEINBERGER R., SAURER W. and SEEBERGER R. Looking at the Simbad player image, that star in the foreground really gets in the way. I would thought it was a reflection nebula and not a galaxy. http://cdsweb.u-strasbg.fr/SimPlay/#target=MCG%2B01-48-001&imtype=color - Kurt

Galaxy hunting
by Kim Hyatt 06 Apr '11

06 Apr '11

It may be a bit early for hunting objects in the "summer" sky, but here's a target I plan to look for soon: MCG +01-48-001. I can't find much information for this galaxy but what little I find is both interesting and puzzling. Has anyone here observed this object before? Kim

BBC Wonders of the Universe Visual Effects
by Jay Eads 05 Apr '11

05 Apr '11

The BBC puts out a show called Wonders of the Universe and a member of that team just put out this video at http://vimeo.com/21914007 The video shows what they perceive to be a planetary nebula (I think it would look different up close), a series of pulsars and a wonderful sequence of a giant star going supernova. I loved the core collapse part. It's about 15 minutes but worth the time on a cloudy and rainy night to watch it. I hope someone enjoys it as much as I did. -- Jay Eads

improved processing
by Joe Bauman 05 Apr '11

05 Apr '11

Hi, I hope I'm not boring anybody with my not-so-fantastic pictures. But Steve Crouch, an Australian who is a member of the SBIG discussion group that I belong to, helped me improve the processing of my view of NGC4565. Here it is: http://www.deseretnews.com/blog/47/10011724/Nightly-news-astronomy-The-Gala… A comment on the Deseret News web site would be appreciated; one on this forum would be nice too. Thanks, Joe

Fw: Re: This past weekend
by Joe Bauman 04 Apr '11

Hi, just wanted to correct the note I sent, below. The galaxy that I photographed last, NGC 4565, is called the Needle Galaxy, not the Silver Needle Galaxy. There is a Silver Needle Galaxy, but it is NGC 4244.
