So tonight I went out with my Pentax 12x50 binoculars on my super Manfrotto tripod (way overkill) with the Far-Sight mount and illuminated finder. M42 and M43 were very nice. Then on to Sirius, M41 and M47. Views were great and so much easier than setting up the telescope.

Fun Hour testing a Fun Scope:

 

ATM 5 RFT S31 (Edmund Filo Tripod).jpg

 

At sunset tonight, seeing was < 6/10, but GOES showed a wide gap (shaped like a molar) coming in from the west.  After dinner, seeing overall was 7/10 or better to the N & W; and, while I was out, I followed the gap east...

 

The 1966 Edmund EQ may look too small for the TN5, but it's not.  If you haven't used one of these, both axes are super slick, and there are no clutches - the knob tips press directly on the steel shafts - so Balance is critical.  It literally glides, and is like holding the scope yourself - without the sore arms.  Sweeping or manually tracking is so dang smooth.  [OK, infomercial over.]

 

I checked collimation on Pollux.  Castor & Algieba at 80x (RKE 8)... lovely.  I stayed at this power, and drifted into Lynx.  Didn't have anything planned - it was a Bonus Night between clouds.  I relied on memory, and managed to find several doubles.  Followed that winding chain of stars in east-end Lynx north into U-Major, dropped to 40x (Jaegers ER16), and found M81 & M82 easily.  The core of M81 at that power was bright; jumping to 128x (Nagler 5) helped spread the central glow out some, and the disk had more of that spiral shape.

 

Thanks again, Terra.  This is the best platform for my oddball Big RFT.  And, since I bought the Mizar AR-1 & ShortPod for Stubby, it's only fair that the TN5 gets an equally stable EQ.

Took the 75mm Polarex out last night, first object was the Trapezium with the supplied 25mm which gives a magnification of 48x . 

All 4 components showed up beautifully. 

 

Had a nice view of Polaris and its faint double.

 

Split Castor, globular clusters M68 and M5 showed up nicely.

Another clear night arrived yesterday. A little bit of haze was there making the light pollution worse. I had the Sears 6305-A 60mm f/15 out in less than two minutes. The light pollution was worse to the west. The second level extension of the house provides protection from it but blocks my western sky to an altitude of 35 degrees. The very light haze combined with the light contamination made the sky look dark gray. I went after bright doubles with the 60mm. The first one was Mu Canis Majoris. At 8:30pm it was already lower toward the south west. The double did not deliver its secondary to the 60mm. I went north to Gemini and Castor. An easy split with at 56x and 112x  with a 16mm Konig (plus 2x Barlow). Two well defined white Airy discs with a first diffraction ring. 38 Geminorum followed. It was well observed at 56x and then at 112x but this time with the 8mm Plossl. The secondary was dim even at magnitude 7.7. Kappa and Delta Geminorum were flops, their secondaries overwhelmed by the light pollution. 

 

Form Gemini I went east southeast to Virgo and Porrima. The 8mm Plossl brought out that "Jeep headlights coming toward you" impression that this star always has on me. Back in the 60s a lot of Jeeps, many from military surplus, roamed the island. There were no major expressways. A lot of roads were very dark. When a Jeep approached at night you could see those headlights close to each other just like Porrima. From Porrima I went to Mizar and Cor Caroli. The 60mm delivered a nice view of both but on Cor Caroli the color contrast was not there. Moving east from Cor Caroli I observed Ksi Bootes with a light orange colored primary and dim secondary. Pi Bootes provided a nice view but Epsilon was not possible. By this time I was observing through broken clouds steadily coming from the east in small groups. At 10:45pm a bigger mass of clouds announced the probable end to the session but before it caught me and the 60mm, we went to Algieba for a last double. The nice light orange-orange pair never disappoints.

 

The 60mm f/15 Towa objective in this particular sample of the 6305s is very good. Images are sharp and stars appear as round Airy discs with a not too bright but well defined first diffraction ring. I have another 6305 picked up as a parts telescope and then restored (this happens to all of us). The original lenses on this one remind me of a comment from my high school senior year English teacher after my submission of a hastily written book report " Your footnotes are for the Birds" and so are those lenses.

it was my first sight of Porrima that turned me on to multiple star systems. Your “two headlights” description is pretty accurate.

JUPITER!! 3 Moons - Io, Cally, Gany! 0520 to 0533. Mizar 60/1000. .965 diag, 20mm, 12.5mm, dirty Ramsden 6mm! Too light to try and catch Saturn - didn't think either would stand out in the pre-dawn - I was only out there to see what Gandalf was about! But there it was, blob with some sort of streak "Jupes?! Summagummagum!" - had the Mizar two feet away and man did I hustle! Got thirteen decent minutes, til the last moon faded and Jup was a ghost in the 6. Tried a hybrid diag with a 20, 15 and 9 - not enough in-focus for that older Meade 9 on the TelescopeWarehouse hybrid, but the Classic diag and EPs did very nicely - banding in the 12.5 dimmed in the 6 with the pre-dawn, but low, dim and dirty, it was still 166x. What a treat! Peach of a scope! Thank Urania for noisy assistants!

Had my first sky test of the Jaegers 50mm F12 optics:   https://www.cloudyni...2#entry11024212

 

Once again, DPAC predicted an excellent lens, and that's what I saw.  I wanted to know whether putting more time & effort into the OTA build is worth it.  Yep.  The J50 is superior to my Hy-Score 457 (50mm F10), and at least as good as my Swift 838 (50mm F14) -- and that's in a kludge OTA made with my Monolux (T) 4348:

[I haven't thanked Dave G lately for advocating building & using your own test equipment, so Thanks Dave!  Takes the guess work out of evaluating these old - and sometimes abused - scopes.]

That’s great. Sounds like you’re going to have a great little 50mm scope. The 50mm x 600mm gold Tower scope that I gave my grandson gives super sharp images.

Tonight, a literal Side-By-Side between the Jaegers 50 test OTA and my 1984 Tak FC-50 with both on the 1985 Tak Sky Cancer (Patrol) EQ:   https://www.cloudyni...#entry11026184

I'm loving this mount!  Next Time, I'll put my 1970s Lafayette (SYW) 60mm F7 against my FC-50.

Today I worked on getting my "Literal side by side",  ready for testing.  Bomber Bob understands the versatility of the Japanese "multi purpose equitorial system design"  that debuted  in the mid 70's.  I have to wait for the weather to cooperate to test my GOTO 80mm Semi-apo's residing on the Mark-X mount.

 

Luckily I had an extra MX-10 balance weight and an extension on the declination axis to get the system nicely balanced.  

 

Cheers

 

Don

Bomber Bob understands the versatility of the Japanese "multi purpose equatorial system design"  that debuted  in the mid 70's.

 

Yes, they let me cut the number of EQs in the shed to a minimum, yet still have quality platforms for my Keeper Scopes.  A Big Issue I have now:  Not enough counterweights!  Seems each maker had their own bore sizes, weight sizes, etc. -- at least with my Goto, Mizar, Takahashi, & Vixen models.  I have to do the most weight-juggling when I want to use both of my Mizar EQs.  Even though some of my Edmund & Jaegers weights fit the Mizar shafts, they are heavier than the large Mizar weights, and with some scopes I need just 1.5x the weight of 1 large Mizar -- like Stubby on the AR-1.

 

Oh!  And it's not just the Classic Japanese EQs:  Terra adapted a good-sized Vixen dovetail base to her 1966 Edmund EQ -- Bingo!!  Since ALL of my fracs have dovetails now, this 1 mount can carry anything from sub-60mm to the hefty 130mm F5 triplet.  And, in less than 5 minutes, I can swap the Edmund with the Tak.  Hhmmmm... maybe I need another Filo tripod...

That's an impressive setup. The mount's color adds a great contrast to the whole set. It would be nice to read a comparison between these two twin Gotos.

Yesterday, in one of the first sunny evenings of the season, I had a quick solar session with the Telementor using both the Baader astrosolar and the brown film, (i prefer the orange sun with the brown film).  I just observed the 2814 group as three small sunspots. 

 

Clear skies!!

looked at the fresh moon and gave first light to my ancient binocular heads that are now officially deemed to be binoviewers.  they work but will need some attention to work well.  i got a nice death star effect for the entire moon in apparent 3d.

Yesterday was Seattle's first day this year over 70 degrees with clear skies and a nice crescent moon.  I grabbed my Unitron 155 and headed to my favorite spot (Kerry Park) for my first ambush astronomy session of the year.  The crowd reaction to the big scope is always great. About 150 people took a look and almost none had ever looked through a telescope pointing up before. Started about 15 minutes before sunset and kept going until 11:00.  Had a few friends join me and as always I had a blast!

The 102mm EQ Unitrons totally shout "TELESCOPE" to anyone walking by. It's like parking a classic British sports car, for drawing attention. Terrific for outreach.

Funny you should say that because I always compare it to a mid 60's Jaguar when I tell lay people about it.
