Nice work, Brian.

 

For others interested, I’ve attacked ESA’s information sheet. This asteroid actually flies by April 29th but it becomes for of a challenge for DSNM because it keeps getting lower in the sky. I suspect it will be mag 12 or brighter for the next couple weeks.

The next meeting of the Astronomical Society of Eastern Missouri Digital (Imaging) SIG will be this Tuesday, April 21st from 7 PM CDT until? We’ll be using Zoom in a webinar format. We might find this too impersonal and change to the normal format for May’s meeting if Covid keeps us from meeting in the real world.

 

Gregg Ruppel will be joining us from his home near Tucson to talk about comets. Gregg is a partner in an observatory we have at Dark Sky New Mexico. Gregg is what I could call an expert comet imager. He has a couple of astronomy pictures of the day (APOD) for comet images. Gregg will present on how he collects data and processes his images.

 

Bill Neubert will talk about his ongoing SQM project. SQM stands for sky quality meter. Bill will talk about different models and how to use them along with test data he has acquired.

 

Here’s how to join us on Tuesday night –

Folks - I'm a wannabe DSNM astronomer, unable to install my gear because of COVID19.  Last year about this time several of us from the Longmont Astronomy Society (LAS, in Colorad) traveled to San Pedro de Atacama (Chile) for 6 nights of astro imaging.  We got only 3 nights in - clouds and rain skunked us the other nights!  I used a borrowed Celestron EdgeHD 8" SCT scope with Hyperstar, a rented mount, and my SX694C camera.  We were supposed to go this year, but those plans got cancelled.  My compadres are now posting reprocessed images from last year's trip, in a futile attempt to relive our limited success. 

 

About a month ago Bernard Miller posted his (tighter) image of the Running Chicken.  Here's my (wider) version from south of the equator.  The rented mount was giving me fits, so this image is the result of about twenty 100-sec subs.

 

 

Some of my other images, mostly taken from Boulder, reside at the same site, if you'd care to scroll forward or backward.

MJ,

 

The detail you have is nice, but it looks like you black clipped the image. You may want to monitor your Levels curve during processing. Somewhere you clipped the blacks pretty significantly.

 

 

The trip sounds like it was a lot of fun. Too bad about the weather but I would take 3 nights at that site.

Really nice image. I’ve love to be able to capture some southern hemisphere data at some point. My luck would be getting to go sometime and run into a week of clouds.

 

Love to have you and other DSNM on the ‘webinar.’ This is our first and we might find it a bit rough but fellow DSNM’er Gregg Ruppel with demonstrate comet processing.

Re: Sky camera

Edited

Well, you do get what you pay for, IMHO. Below is a video from the other night from my SBIG.  It is only 640 x 480, of course but high res is not required. It is sensitive to faint clouds as you can see later in the night. Plus it has been running for well over a decade with zero issues...

Sorry about the dome crud - I need to do my spring cleaning on the dome - not used much in winter here since it is mostly cloudy in the winter in the Pac NW.

As an aside, note the  Lyrids I picked up early in the night



I also do not understand why we need multiple cameras. Every other remote site I know of has a single high quality All-Sky available to everyone on the remote site's own web-page or server.

Take Care

New camera sounds great. I do have to say that I have had the SBIG All-Sky 340 for about 10 years at home in my dark sky site. Alan put a red Wratten filter on it before they sent it to me and I can't imagine anything better. It is the monochrome, of course (color versions of any all-sky suck) and it is sensitive enough that I can see shifting patterns of skyglow on it.
