Nice catch, Brian.

 

I think there is another somewhat bright morning one in C/2020 A2 Iwamoto. I think it is currently in Draco and heading south. Might we worth pointing at once the moon is a bit out of the way.

We are in a real drought when it comes to good comets.  T2 is OK, and will max at about mag 8.   

C/2019 Y1 (ATLAS) was to peak at about max 14 in March but it now looks like it will hit 8.   Here’s a shot I got last night:

https://spaceweathergallery.com/indiv_upload.php?upload_id=159414

 

11x3min exposures.  No filters or autoguiding.

 

Reports show it at mag 9.5.   Unfortunately, Y1 stays low in western twilight, so no great display.

I totally agree with Dan.  My recent shot is very tiny compared to this!

Hi,

This is an image of Stephan's Quintet which is comprised of five galaxies in the constellation Pegasus. The five galaxies are NGC 7320, NGC 7319, NGC 7318a, NGC 7318b, NGC 7317. Four of the galaxies, NGC 7317, NGC7318a, NGC 7318b, and NGC 7319 form a physical association and will likely merge. The fifth galaxy, NGC 7320, is a foreground galaxy about seven times closer to earth than the other galaxies.

Apparently, it required the ISP to come out and fix it, that implies that it was the cable or fiber modem (whichever is the case) and not DSNM equipment.

NGC 1760 in Bi-Color

Bernard Miller
 

Hi,

This is an image of NGC 1760 shot in bi-color with Ha and OIII filters and RGB stars added. This is a large complex of emission nebulae spanning over 1,000 light years connected by glowing filaments. It is about 160,000 light years away in the Large Magellanic Cloud (LMC) in the constellation Dorado. It is one of the most active star forming regions in the nearby universe. The large open cluster NGC 1761 can be seen in the center of the image. This cluster contains some of the hottest and most massive stars in the universe.

Comments and suggestions welcomed.

Re: Roof Closure Building 8 Too Early!

Frederick Steiling
 

I had a group message from Michael on 1/23 stating the following:

"We experienced some light condensation this morning.  I have asked Al to set the humidity parameter to 80% and auto close the roof at 430am if the weather station has not ordered its closure prior to that time.  I will keep you up to date on the condensation issue.  Michael"

I agree that it's time to revert the change for 4:30 closure.  If weather parameters are safe, closure should be triggered on a daylight parameter, preferably relaxed enough to nab sky flats if anyone needs them.  I was down there installing my gear last week and manually re-opened the roof one night after 4:30 for continued testing and didn't experience any issues.

If the behavior persists, I'll also reach out directly.

I tend to be able to image up until the sun is about 16 degrees below the horizon if pointed west so you can even cheat the system a little more.

Subject: [DarkSkyNewMexico] Roof Closure Building 8 Too Early!

 

The last two nights that the roof was open on building 8 I noticed that it was closing around 4:30 AM.

Given that astronomical twilight is at about 5:45 AM, this is wasting an hour and 15 minutes of imaging time. Worse, during this phase of the moon, most or all of that is moonless time. In fact, even when the moon IS up during morning AT (the opposite side of the moon calendar), it is common to image a bit PAST astronomical twilight since one is typically using narrowband filters anyway and a small amount of early twilight is less than what the moon illumination contributes. In that case one should be closing as much as 30 minutes AFTER morning astronomical twilight. There is zero safety hazard to this since sunrise is still a half hour or more away in the most extreme case.

I have my own roll-off and have imaged at another remote site as well and have never heard of early closure for anything but weather.

I have talked to my imaging partner and he is in 100% agreement - he has imaged at three other remote sites and says none of them did anything like this.

How do we get this changed?
