Cool photo!  It demonstrates what an atmospheric dispersion corrector can help with, looking at the color gradient from top to bottom.  I've been thinking about getting one.

...just to clarify, it was just that this Saturn through the D-IK was a spur of the moment thing in very unfavourable seeing & elevation at the time.....Saturn is actually high Downunder atm & we utilise an ADC for lower-elevation imaging as well as for the Mars from last year's apparition where we obtained our highest resolution images ever despite most imaging done at 48° such as these: http://momilika.net/...mAT150pcFIN.png  (click on image for full sizing...)

Wow, that's very impressive Mars work, very well done!  I had forgotten where you are.  Enjoy the high planets while they last!

I found a free RV6 down the street from me. It's missing the original focuser and the hole has been bored out too much to stick the old one on. I'm going to stick on a GSO Crayford focuser and paint it hot pink, since the original paint is trashed and I've already restored 3 of these with the standard paint job.

Tomorrow I will look to get started on what I can do to clean up the 80mm Cresent scope I picked up earlier this week. Working Monday through Thursday this week I already got in my 40 hours, so my manager gifted me another three day weekend.

 

I'd actually prefer to work and collect the bonus overtime pay, but its also nice to be getting these random three day weekends. I have now had three of them in a row, they almost feel like a mini vacation.

 

I love my new job!

Why not do like a space themed wrap? Maybe with a Hubble image super high res? Then donate for outreach?

Every club in the area already has enough outreach scopes (and hardly uses them)....

We get more donated scopes that we could possibly use.

Flip 'em and save up for an NV setup with an H-alpha filter (~$6k). Best thing I've ever seen for outreach and you can do it from any level of light pollution.

70643A7B-D2CF-4CDB-A82F-BBA48027AA62.jpeg Just picked up a Unitron model 114 complete. Well, I need the dust cover for the objective. Beautiful telescope Can't wait to try it out!

Being nonprofits, many clubs are forced to keep donated scopes for a period of time before selling. Often years.

Took the Unitron 114 out for a quick look last night. After reading all the alarming articles in CN forums about bad Unitrons, I was hoping mine would not be in that number. I first used the Unihex with .965 eyepieces and noted the dim images (I am used to more aperture). My neighbor had his plant lights on and so it was not as dark as my back yard can be (I can see the Milky Way when his lights are off). Thankfully though, the quality of the images was encouraging. Then I went to some 1.25 eyepieces and was struck with the clear images! Jupiter with a 9mm ep looked amazing for a 60mm telescope. Saturn also looked good, and I could barely make out a cloud band and hints of the Cassini division. Did not do a star test yet, but I was very encouraged by the quality optics in this old little scope. Also, it looks great in my office.  :)

I'm on a roll lately! Pierre Schwaar's sister apparently still has some of his stuff and I am picking it up Wednesday.

Yes, I'm down-sizing.  Yes, I bought another old scope -- BUT, not a Mizar...

 

Kenko GO-SCOPE 540:

 

Kenko GS-540 AS01.jpg

 

I posted the ad link for it a while back.  It didn't sell.  Ad popped up again, so I nabbed it - cheap.

 

- A test for me of Kenko optics;

- At F9, an uncommon Focal Ratio for a 60mm;

- At 540mm, almost the same Focal Length as my Mizar GT-80S F7;

- Interesting comparisons with my Excellent Yamamoto 60mm F7;

- I missed out on that RARE Kenko 60mm fluorite APO.

 

The Lens needs work:  It pigged-out at the Andromeda Strain Buffet, then went back for seconds!  Will probably take days of peroxide soaking to kill all the growths...

Guido's post about Carton optics is par for the course:  Your experience with the Unitron vs Carton lenses is just like mine. When comparing observations with the 60mm f/15 Unitron lens (mounted on my 6305 Towa refractor) and the 60mm f/17 Carton refractor. It's very difficult to tell them apart. Both objective lenses deliver excellent performance.  LINK:  https://www.cloudyni...#entry11430133 

 

So... What about that really bad Carton 60B (60x800) that I gave away??  It's an example of Quality Lens in a poor quality OTA.  New Owner is gonna ATM it:  Build a decent OTA around the lens, and enjoy their first Classic 60 -- like with Guido's N-S lens in a Sears (T) 6305 OTA.  (No surprise that an N-S 60 F15 is an improvement over a Towa!)

UPS dropped it off at 1940L....  Kenko G-Scope 540:

 

Kenko GS-540 Delivery S01.jpg Kenko GS-540 Delivery S02.jpg Kenko GS-540 Delivery S03.jpg Kenko GS-540 Delivery S04.jpg

 

The Lens doesn't look as bad as the ZEN photo -- the growths appear to be on the eye side of the flint (R4).

 

Solid!  Tube feels like an aluminum baseball bat...

 

Got the lens out of the cell.  Crown is perfect.  Flint had a couple of small spots on the sky face, and a bunch on the eye face.  Already have it soaking in a Peroxide Bath...
