Sh2-33

Gregg Ruppel
 

Hi all:

Sh2-33 in the constellation Serpens is an odd ball entry in the Sharpless catalog.  Most of the Sharpless objects are emission nebulae with a few planetary nebs and supernova fragments as well.  Sh2-33 appears to be just a dusty nebula with some back illumination(?).  Two hours of data through an Ha filter showed nothing.

Arp 1 + 285

Dan Crowson
 

Arp 1 (NGC 2857, UGC 5000 and others) is a grand design face-on spiral located approximately 238 million light-years away in Ursa Major. This one is part of Arp’s ‘Low Surface Brightness’ class.

 

Arp 285 consists of the two distorted spirals with tidal tails. The top galaxy is NGC 2856 (UGC 4997 and others) and the bottom is NGC 2854 (UGC 4995 and others). These are found in Arp’s ‘Double Galaxies – Infall and Attraction’ class.

 

Luminance – 24x600s – 240 minutes – binned 1x1

RGB – 8x300s – 40 minutes each – binned 2x2

 

360 minutes total exposure – 6 hours

 

Imaged April 26th, 27th and 28th, 2019 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

Dan,
We were down this morning at 11:20am EDT (9:20am MDT) when I first attempted to log on. Was not able to get into 2 of our PC's. (However my webcam which is hooked to Hughes satellite internet was working).
Then just 15 minutes later all was well. Speed test showed 90 down, 23 up, 2 ping. Good. I worked on the PC for an hour.
Just now I logged on to transfer some files home. Seems quite SLOW right now but is working for me.

Can you tell what link you're actually using? It sounds like you could be on the hughes. From your PC, you could do a tracert 8.8.8.8 (Google DNS server). I'm curious if it shows you going out the Valley fiber or something else.

Arp 285 consists of the two distorted spirals with tidal tails. The top galaxy is NGC 2856 (UGC 4997 and others) and the bottom is NGC 2854 (UGC 4995 and others). These are found in Arp’s ‘Double Galaxies – Infall and Attraction’ class.

 

Luminance – 24x600s – 240 minutes – binned 1x1

RGB – 8x300s – 40 minutes each – binned 2x2

 

360 minutes total exposure – 6 hours

 

Imaged April 26th, 27th and 28th, 2019 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

Subject: [DarkSkyNewMexico] Sh2-33

Hi all:

Sh2-33 in the constellation Serpens is an odd ball entry in the Sharpless catalog. Most of the Sharpless objects are emission nebulae with a few planetary nebs and supernova fragments as well. Sh2-33 appears to be just a dusty nebula with some back illumination(?). Two hours of data through an Ha filter showed nothing.

SkyAlert Weather Monitor

Howard Anderson
 

Hi all,

I just bought a SkyAlert Weather Monitor.  Have not been
down to the site to install it yet but I see at least one of you
has this device and are displaying its results out on the internet.

QUESTION:  in the following SkyAlert image, how do you tell if it
is likely to be cloudy?  Are you looking for the "Sky Temp" to
rise to someplace within the grayed areas?  How are the Gray
areas determined?

I had cloud conditions all calibrated on my Foster Weather Monitor but its communication
chip was damaged by a nearby lightning strike several months ago.  I replaced its comm chip
but was unsuccessful at restoring it to working order.  The device no longer seems to be
available from Foster...  Thus my purchase of the SkyAlert system...

Thanks!

Howard
