Beautiful Full Moon yesterday

I've been waiting for a clear night with a full moon for the last three months.  Yesterday was payday ...

Dark Skies - Part Deux

Friday was a great day in Luray.  Clear blue skies, some wind but not too bad. And the temperatures were a bit chilly, but warmed up in the afternoon.  Joan and I decided to stay the complete day in hopes that the evening skies would be good for astro-photography.

So, rather than spend the whole day at the B&B we decided to take in some sightseeing and headed over to the SkyLine Drive,  in particular, Stony Man Overlook.  The views were fantastic; much like I remembered them back a number of years ago when we drove the entire length of the drive, twice!  Things changed a bit - like the $20 entrance fee now.





After the great time of outdoor adventuring, we had a really good meal at the SpeakEasy in the Mimslyn Inn.

Arriving back at the cottage, the thin crescent moon was getting ready to set, and, as expected (as well as forecasted) the winds picked up - blowing at 20-35 MPH.  But I had hopes that the winds would die down after 6:00 or 7:00 so I set up the scope and waited inside in the warm cottage.

Eight o'clock came and went - winds howling outside. Nine o'clock arrived on schedule - still howling winds.  Ten o'clock, and time for tea and cake provided by our hosts - still the wind blew, but not as bad, as there were short periods of calmness.  Question is, would it be enough to capture a few 180 sec subs? 

Well I managed to get five fairly decent 3 minute subs to process at around 11:30 PM.  The stars aren't perfectly round, but the sky was crystal clear.  So here is the redo of the Pleiades from Wednesday night, minus the halos from high clouds.

Finally, by 12:00AM the winds ceased - yep, nearly 0-5 MPH!  That was the good news.  The bad news?  The clouds started to roll in.  My sky conditions forecasting software indicated that clouds would thicken until 2:00 AM then scatter a bit.  So it looks like its going to be a long night.

At around 1:30 AM there was a clear spot to the area where the Andromeda galaxy was located. This is the closest galaxy to our own Milky Way at about 4 million light years distant.  In a clear dark sky you can see it with the naked eye extending out larger than the size of our moon.  So I set sights for Andromeda (M31) and captured eight 3 min subs before clouds interfered again.

I then set up the telescope in fully auto-mode to capture some other objects while I got some much needed shut-eye.  Need to process them yet, but, I was pleased that at last a really good outing in the darker skies of Virginia.  I will need to return here again to capture some other hard to image deep sky objects (DSOs as we Astrophotographers call them).

Vacation, B&B and Dark Skies

Well the wife and I finally got to go on a well deserved vacation to kick back and relax.  We ended up at the Piney Hill B&B outside of Luray Va, picked because 1) we love B&B's and 2) it is in a semi-dark site area, at least two to three Bortle numbers darker than at home, and I wanted to use my telescope in a dark sky.

So on Wednesday, November 11th, we drove the new Chrysler Town and Country, packed to the gills (well almost) with telescope and telescope gear (yeah - we took some clothes and other stuff too).

We rented one of the two cottages on the B&B property so I could have ample area to set up, and not bother the rest of the guests.  Site was great - ample views to the east, north and west, and to the south if I decided to set up on the other side of the cottage.

Wednesday night was a bit cloudy with high clouds but still seemed OK for setting up the scope and giving some photography a try. Thursday's forecast wasn't good, so I didn't want to pass up any opportunity. So soon after arriving I set up the scope. Boy what a chore!  New location meant new Lat and Long settings for the mount and software. Then I needed to set up the tripod with nearly correct North-South orientation so I wouldn't have to move the whole telescope after it was mounted.  That didn't work ... so I needed to re-orient the tripod and scope together a few degrees. That's about 200 lbs+ and at my age that's a good amount to be moving especially in the awkward position I needed to be in to get the thing to move.  By the time I got everything setup, the clouds were moving in.

I decided to install the Hyperstar lens on the scope and try imaging the Pleiades star cluster.  With the high clouds the final image shows some halos and is a bit diffuse all around, but compared to home, it was awesome.  I was able to image at least 120sec with the HS with no image fogging due to light pollution (back home, 60sec is about all can get).

Next up would have been the Pinwheel galaxy, M33, but the clouds finally made it impossible to continue. I got one 2min sub and then had to pack up. But even the single sub showed quite a bit of detail.  A complete set of 20-30 subs would have made for a great final image - these dark sites really are nice.

Although I couldn't image anymore this evening I did see a nice bright meteor streaking slowly across the sky - probably a Taurid, since the Taurid meteor shower was to peak this night.

Next day turned out to be much better than forecast, the rain ended soon in the morning and the rest of day was mild and sunny. We stayed at the cottage until about 1:00PM and then headed out to Dayton VA, to the Patch Work Plus quilt shop.  Both Joan and I purchased some goodies - Joan got a lot of cool material and I purchased a Dr. Who quilt kit.  After eating a late lunch at a local restaurant we headed back to the B&B.  The sky was clear and the forecast was for clear skies.  The only possible kicker would be the wind as the forecast was for some breezy conditions.

I set up the scope at about 5:00PM, in the wind, hoping that it would die down during the evening.  The forecasters said that would not be the case, but hey, I set up anyway.  Well, 30-40 MPH gusts and 25 MPH sustained winds does not make for a good night for observing, let alone photography.  Had to give up the attempt rather early as the winds were not going to subside.  All was not a total loss - I did get to see something I haven't seen in over 35 years - the Milky Way! It was wonderful.

I decided to leave the tripod outside. There is always a chance that tomorrow night might be better. Forecast is for 25MPH winds with 40+ gusts so I'm not expecting much.  We'll see.
