I know they are cheaper by the dozen, but I only needed one.  Plus technologies are a changing.  Anything you can uses is out of date!

Many on this list have heard (read) me talking about the PVS-14 night vision monocular. I’ve prepared a short report on the device. Please see the attached.

 

Last night, the building clouds discouraged me from opening the observatory so I just set up my 10-inch Orion Dob in my driveway and used the night vision monocular to tour the sky. I used a 50mm Super Plossl that only gives 24x in the 10-inch but provides a wide 2.2 degree FOV. That finedresque  field coupled with the brightness enhancement of the NV device makes star hopping quite simple.

The entirety of Markarian’s Chain can be enjoyed in a single stop!  Galaxies show up quite well in the device, and edge-on galaxies show up particularly well. The device is very red sensitive and galaxies seen edge on are reddened by dust. Globular clusters, composed mostly of old red stars, also show up wonderfully. Even at the tiny (24x) scale, M13, M3, and M5 were magnificent.  

 

Some would say that NV enhancement is “cheating” from a visual observing perspective.  Others are embracing the technology.  What do you think?

I anticipate the more militant purists to be incensed.  I’m leaning toward allowing NV for the Planetary Nebula  Program if the League decides to allow it generally.  My goal for the program is just to get people observing planetaries, its irrelevant to me how they do it.  Few PNe will be improved anyway.  OIII emission is not much enhanced.  But some objects will really benefit – I remember being amazed at how the Bug Nebula (NGC 6302) looked in the 30-inch through the device.

Observing Sunday May 22 2022

Kent Blackwell
 

I've been threatening to replace the focuser on my 16" f/6.2 Dobsonian for 25 years. I finally made the move. After changing out the focuser, never as easy as task as one might think I wanted to test all my eyepieces to make certain they came to focus. They did, a 31mm that focuses closer than any eyepiece in my collection as well as a 27mm that focuses out further. Earlier in the day I carefully leveled the focuser and collimated the telescope. It's such a joy to use the new focuser.
Although the transparency was "milky" (it was 95-degrees and hazy during the day) seeing was superb. My favorite object of the night was the small planetary nebula NGC 6210 in Hercules, "The Turtle". At 710x I detected its outer envelope and even could see its "dome-like" appearance, hence the nickname. It was truly, "the best I've ever seen". Equally impressive was the globular cluster, M 5. I couldn't push the power beyond 370x, but stars were pinpoints at the power. Some stars were blue and a few red ones. It was just beautiful.

I remember seeing (and seeing through) John Raymond’s night vision device.  Quite possibly at that same ECSP (?) .  I’ll take your word for it being a PVS-7. It was novel, but I didn’t like the green tint or the speculation as I recall.  I also saw another one at a DelMarVa Stargaze – I forget who had one. 

 

They left me with the impression that NV wasn’t anything I was interested in spending money on. The white phosphor model changed my mind in an instant.

 

I’ve used it in the 30-inch, the 18-inch and in the 10-inch Dobs and tried it with the 20-inch RC at our Patterson Observatory. It’s wonderful in the bigger apertures of course, but the wide fields possible in the 10 are just incredible (with the 65mm Super Plossl it yields 2.8 degrees). The view of IC 434, the Horse Head and NGC 2022, all in a single field of view, just knocks my socks off.  It rivals any photograph I’ve seen of the area!

 

Omega Centauri in the 30-inch, enhanced with the NV literally takes my breath away every time I look at it.

 

What I find most exciting though, is the nebulous stuff that doesn’t even appear in the charts and apparently has no designations, the winter Milky Way is particularly rich in unmarked areas, but there is a lot more than the charts imply in the summer Milky Way too.

Great article! 

 

I have been hooked since John Richmond showed me a pair of PVS-7’s at ECSP.  I purchased a pair of PVS-7s Gen 3’s from a friend who deals with military surplus ~ $1800,  Bino view, green phosphors , with single objective, about 4 years ago.

 

Bought a 1.25 adapter and attached them to my 8” Schmitt, and then a filter wheel with several HA filters.  I am being still impressed.

 

The original 1.25 adapter had a shoulder on the 1.25 tube that restricted insertion into focuser, and could not reach focus on most Dobs, including Kent’s 25”.  I 3D printed one without a shoulder and it did achieve focus on several Dobs.  Did not trust the plastic part holding the expensive NV’s, so I found a metal adapter online without the shoulder and bought it.  That works great on the clubs 18” Classic Obsession and every DOB so far.

 

I also found online an adapter that allows the attachment of Canon DSLR lens to the PVS-7’s, and have attached several lens to the NV’s.  You can also buy the 3X adapter made for the PVS-7 for ~ $350.

 

I designed and 3D printed a soft adapter, that firmly holds a 1.25” filter in front of the PVS-7’s 1x eyepiece, and allows quick and easy changes of filters.

 

Steve Shellman has both the PVS-7 and PVS 14s, and I have enjoyed the views of the PVS-14s thru his 30” Dob.

We use filters to enhance viewing, we use bigger apertures and better glass, we use multicoated eyepieces. Image intensifiers are just another way to enjoy our night skies. I'd certainly vote to allow it.

Many on this list have heard (read) me talking about the PVS-14 night vision monocular. I’ve prepared a short report on the device. Please see the attached.

 

Last night, the building clouds discouraged me from opening the observatory so I just set up my 10-inch Orion Dob in my driveway and used the night vision monocular to tour the sky. I used a 50mm Super Plossl that only gives 24x in the 10-inch but provides a wide 2.2 degree FOV. That finedresque  field coupled with the brightness enhancement of the NV device makes star hopping quite simple. Imagine galaxy-hopping the Virgo-Coma galaxy cluster with the ease of reading a star map or scanning an image. The entirety of Markarian’s Chain can be enjoyed in a single stop!  Galaxies show up quite well in the device, and edge-on galaxies show up particularly well. The device is very red sensitive and galaxies seen edge on are reddened by dust. Globular clusters, composed mostly of old red stars, also show up wonderfully. Even at the tiny (24x) scale, M13, M3, and M5 were magnificent.  

 

Some would say that NV enhancement is “cheating” from a visual observing perspective.  Others are embracing the technology.  What do you think?

 

We Astronomical League observing program coordinators will be meeting virtually to discuss and vote on incorporation of night vision into the observing programs shortly. I anticipate the more militant purists to be incensed.  I’m leaning toward allowing NV for the Planetary Nebula  Program if the League decides to allow it generally.  My goal for the program is just to get people observing planetaries, its irrelevant to me how they do it.  Few PNe will be improved anyway.  OIII emission is not much enhanced.  But some objects will really benefit – I remember being amazed at how the Bug Nebula (NGC 6302) looked in the 30-inch through the device.

After heavy rains, Dee and I encountered some flooding in Virginia Beach.  We were on 20th Street heading toward the Ocean Front late one night and suddenly found the road flooded.  It was more than a puddle, but I couldn’t see the extent or be sure of the width or depth in the dark, so we detoured way north to higher ground up around 40th St.

Ted,

I remember the low water crossings in San Antonio, Texas, and how some people died trying to drive across, but got washed away.  It sounds like it's even worse in your part of Arizona.  In San Antonio, it might not even be raining, but if there was a cloudburst in the Hill Country 50 miles north, the water would soon fill the low water crossings in town.

I remember my first rainstorm there as a 2LT at Fort Sam Houston.  When I drove my little 1960 Volkswagen beetle across a 3-4-inch flow across the road, I almost floated away.  I never attempted that again.  One time it stormed all night Saturday night and Sunday morning, and many streets and roads were underwater.  I had to get my map out to find the high ground and trace out a route to get to church Sunday morning.  The northbound lanes of Interstate 10 were completely underwater, and northbound traffic was routed up one of the lanes on the southbound side.

Another time we were at church on a Wednesday night, and it stormed all during the service.  To get home, on Loop 410 (I-410), an underpass was flooded (with a car in water up to its windows), so we had to take the exit and drive north several miles to rural Loop 1604 and go home the LONG way.  

Here in Tidewater there is local flooding in Norfolk (especially during high tides and nor'easters), and some low spots in Pungo and toward Sandbridge, as you know.  I live in Aragona Village, one of the highest areas in Virginia Beach, so I have no trouble with flooding.

I never realized that Arizona has a monsoon season.  We had one in Bangkok, Thailand.

Next to the fire danger, it’s the biggest challenge to living here.

It’s not unusual to have the road become completely impassible, for several hours (days if the road collapses) a couple of times during monsoon.  We’ve clocked debris in the wash traveling about 40mph and estimate a depth of 4 to 5 feet in the center of the larger wash when it is in full flood.  It’s most dangerous, however, when its shallow enough to tempt a crossing. Two of the three washes have claimed lives, from people attempting to drive through. We own and maintain our own roads – the 60 or so families up here comprise a road maintenance district. When the road collapses, or fills with debris, we are on our own to fix it.

We need some monsoon here in Colorado.  No measurable rain since last August.

But, they are predicting snow on Friday night and Saturday of up to 6-10” go figure!

Hey George,


Yes, I've talked to AstroBuddies that had heard I'd retired and dropped out of astronomy altogether. I'm just waiting for the pandemic to finish its death march. I have two local granddaughters that aren't vaccinated, so I'll be solo observing for the foreseeable future.
