I just sold my 20" Obsession and of course it clears up that same night (last Sunday).

 

So I took advantage of rare clear sky and 46degree (warm) temps to spend time with the Orion Nebula using my AP 7" Starfire, Cave 8" RFT and Tasco 10te.

 

Such different experiences of the same object.

 

The Cave was best for its wide field view with a Galoc 16. A bit touchy to get focus precise, but quite a bit of real estate to view.

 

The AP Starfire was just amazing as always, great contrast and detail.

 

But I spend more time with the Tasco 10te having fun with trying virtually all my .965 EP's. It's interesting that with a larger object with more stars, the smaller size EP's don't feel as narrow.

 

Bottom line is that I noticed a curious effect; moving from the Cave to the AP to the Tasco, the stars became smaller and tighter, and this changed the entire feel. I actually came to appreciate the views in the Tasco more this way. Absolute pin point stars create a feel of distance, whereas the Cave felt more intimate and the stars felt closer. This in turn made the nebula feel different

 

All in all a great night with the Classics - after months of clouds it was like a homecoming.

 

Best,

Steve

Well, in this season of stargazing reports drought, I propose that virtual observations are allowed.....

 

Yesterday I used my trusty TV Pronto + homebrew cellphone jig to simulate real views with SkySafari + Altaz-EQ convertible SkyWatcher mount. I wanted to further familiarize myself with two-star alignments. Previously I was using the routine alignment process of mount, where the list of available stars is restricted by certain criteria to facilitate use (or so Mr SkyWatcher thinks). This was a problem because my backyard views are already severely limited by trees, and I seldom had enough stars in view to choose from the controller's list. However, recently I discovered on the mount manual an option to remove the filter and finally be able to use the bright stars that I can see.  I also took the opportunity to start tuning the settings of SkySafari on my new Galaxy S9 phone. 

 

Obvious caveats: indoor the GPS does not work well, also the phone's compass is off. But, to practice mount setup and use, this does not really matter.

 

So I did a nice two-star alignment with Betelgeuse and Algieba, two stars that I estimated would have been more or less in sight (there was a snow storm ongoing btw...).

 

Then with the GoTo I slew the Pronto to M95 and voila' it was (more or less... lol.gif ) in sight, despite being a bit low and in the light-polluted section of the sky (wink.gif) .

 

Finally I tested for the first time the "Parking" feature of my mount, which should now be ready for the next session. Not a bad session overall.... I did not even have to put back the telescope's front cap, because I never took it off...

Just looked at the moon with my 1960 RV6 and even with a 3mm Delite and 2.5x barlow the image is just as good as it was with my 6" APM ED.

Just wondering . . . RV6, 6" f/8 newt?  about 1200mm fl., with a 3mm eyepiece, that's 400x, and with a 2.5 barlow, that is 1000x.

All I can say is, wow!

Image gets dim jim, and a few eyebrow hairs get mixed into the view, but the image is not that bad at them crazy powers.  Just the 3mm Delite alone is super nice. I want this mirror tested and recoated.  May build a whole new OTA around this mirror.

Hi all,

 

I was up relatively early this morning to get a peek at Venus, Saturn and Jupiter and although the air was cool and the sky looked clear the only one I was able to really enjoy was Jupiter.  I was using my Tasco 12TE-5  and with it I could see the four largest Jovian moons and make out the belts but as things often go, viewing suddenly went downhill and the image began to waver between somewhat clear and absolutely awful.  I was a tad disappointed as this was the first time I have been able to get out under dark skies in quite awhile but I suppose that's how it goes!  Still, it was wonderful to be outside and see those beautiful planets glowing in the slowly brightening dawn sky.

Taking advantage of a clear (but not perfect) Saturday, I got my daughter and my neighbor to help me assemble the Spacek 6"-
(need the additional pair of hands to land the mount on the pier, and the OTA on the mount).

John with Spacek.jpg

The Moon, once it rose high enough to get to clear air, showed some really nice detail (I was using my University Optics 32mm and 16mm Konigs)

Feb Mn (1).jpg

Later on, the sky quieted enough to let me see Orion Trapezium E and F (they swam in and out of view due to the turbulence).

At the end of the session, I figured out a way to store the assembled Spacek in my garage...so it will see a lot more use from here on!

Those are awesome pictures John.  The detail is amazing.    Proves you do not need high power for amazing detail.  One would never see the contrast that allows for that kind of detail at high power.   Looks like there is a lunar compound in the one picture.

There was a minor break in the clouds tonight, not long enough to bring out the new scope, but i thought I’d try out the little Unitron 127 on the moon. So, with a Goto prism diagonal and Goto HM25mm eyepiece, I pointed the little 42mm objective at the moon. Wow. I’m impressed. Black background and nice clean edge to the moon with no obvious color fringing. True, it was only 28x mag but I only had a short amount of time to have a look. The moon had the 3D effect I’ve always heard about with small objectives, but have never actually observed.  Until now. The little Unitron is a wonder. This may beat the Swift 838 in terms of my favorite tiny scope.

been there done that.  That is why I like using a dslr.  However, the imagers are best for long exposures and no shutter to screw things up.

Anything beats waiting till the next day to have your film developed and find out they’re out of focus. At least you know it didn’t work out tonight. The question is why are the images are blurry.  Focus? Tracking?

I reprocessed the photo from February 8th and got this (It looks incredibly bad compressed so I hosted it off-site):

And here's a pic I took with my phone during an exposure (pretty good considering no flash):

Picked up a used Quick Set camera tripod yesterday to use with the C90 I bought on the weekend. Made my first observations yesterday evening. The rising full moon was clear and detailed, filling the entire field of view through the Celestron 25mm Ortho eyepiece, but very bright as could be expected. Stars resolved to sharp pinpoints of light, except for Sirius, which was a brilliant bluish white but more than a pinpoint, and Betelgeuse was a similar reddish sight.

 

With the temperature in minus double dights Celsius, and frost forming on the steel legs of the tripod, it was a short first look with the scope. I'm usually up and off to work well before dawn, so I intend to make an effort one of these mornings and have a look at Venus and Jupiter.

Another rare, partly cloudy night. Took a break from packing up some scopes for shipping to try out a new eyepiece I picked up. Grabbed the little Tak FC-50 and the original version of the Masuyama 25mm 65 degree eyepiece and had a look at the moon. Beautiful contrast and very sharp eyepiece. Can’t wait to give the Masuyama a try in one of the bigger scopes. The Orion Nebula was a tiny little smudge at 16x and 4 degree field of view  in the little Tak with the Masuyama. Rain forecasted the next several days.

Today I observed that the tray on my tak em-1 Mount makes for a

good place to store my beer between sips while I continue work on Cosmic Acres.

When the Moon is in the seventh house and Jupiter aligns with Mars... 

 

https://www.youtube....h?v=hwNjcZzosa0

 

I get a chance to use one of my 13 telescopes!  Tonight -- and tonight only! -- is forecast to be the only "clear" night for yet another week.  And, I don't go into work tomorrow:  I have a quarterly FJI (neck injections).  This is how sad the situation at The Swamp is:  I'm HAPPY to have 8 needles stuck between my vertebrae in the morning, since it means I can stay up later tonight.  And, the pesky Moon doesn't rise until 2330 local.

 

So, IF the NWS is right, I'll have the mighty Dakin 4" F10 BAD (Baker achromatic doublet) on the Goto 106 in a DSO side-by-side with my APM 152ED F8 APO on the Meade StarFinder.  Doesn't matter if the wind doesn't die down.  These two fracs are short & stout -- and wind resistant.

Well, obviously, the 6" APO will whoop the 4" achro... or, will it?

 

The APM 152 will have the Takahashi FC-50 as ballast:

 

APM ED 152 S062 (Takahashi FC-50).jpg

 

The Dakin 4 will have its matching Lafayette (Yamamoto) 60mm F7 guide-scope:

 

Dakin 4 - Restore S06.jpg

 

The Dakin 4 will win the mobility contest (tonight is a test of the "new" Goto 106 EQ mount from Dave Trott).  The APM 152 will win on color correction.  Resolution?  6" should beat 4" -- but compare Jupiter photos between these two fracs, and see how good the old achro can be.  But from my downtown back yard, aperture wins for finding & enjoying most faint fuzzies.  I'll have the 2" CLS filter in the Dakin -- the APM won't need it.

 

* Just checked the AWC (Aviation Weather Center) site:  The last straggling bits of upper-level moisture are sliding SE, and there's nothing behind them.  DSO seeing should be 8+ / 10 tonight -- thank the Good Lord!!  I put all the gear out in the shed this morning, and opened those huge wooden doors.  About 3 hours to go, and y'all won't hear from ol' BB for a while -- unless I come in for a nap!

4 hours of bliss with 3 very fine refractors:  APM 152 F8 ED, Ralph Dakin 4" F10 achro, & Takahashi FC-50 F8 fluorite.  Successful tests of the Goto 106 EQ mount on the Edmund tripod, the TeleVue 4mm Radian eyepiece, and the Astronomik CLS broadband LPR filters.  

 

As expected, the APM showed more faint cluster stars than the Dakin 4; however, with the CLS, the 4" wasn't far behind.  For example:  There's a nice curved strand of stars on M35's northern border, and I counted 17 in the APM, but only 12 in the Dakin.  But with the CLS, the Dakin showed 14.

 

The Tiny Tak makes a great finder for the APM, and overall gave better views than the Yamamoto 60mm on the Dakin -- 10mm larger aperture didn't trump the materials & craftsmanship of the 50mm fluorite.

 

Seeing got up to 9 when a surface breeze blew away the pending fog (the ground is like a soaking wet sponge), but averaged 8 for most of the session.
