Looks good now but it was very dirty. This was by far the most difficult objective to remove from its cell. I had apply even pressure to slide the elements out of the cell cause it was so tight. Fine corrosion and dirt particles were the culprit. Once everything was clean it gently slid back in the cell. Nerve racking!

Would be interesting to see how it tests in DPAC.  These early lenses were all very good.  The early ones I tested in DPAC were excellent.

Eventually I'll DPAC it.

Rolled out the  scope for first light last night. Mainly did star testing and a few easy objects. The star test is very nice, possibly the best of four 4" Unitrons I've owned but that's going by memory. The Orion Nebula was excellent but I would say my late model Unitron 152 with the green coatings my have had slightly better contrast. Hard to say for sure since it wasn't a side by side.The trapezium was very nice showing both E & F companions. Used a 1.25 adapter with various eyepieces. Meade smoothie Plossls and super-wides mainly the 24.5mm & 18mm smoothies to Nagler Type 6's  5mm, 7mm,9mm,11mm,13mm,and 16mm. All performed beautifully. I compared the old first gen 7mm Nagler vs the newer 7mm Type 6 and the difference while not a lot is certainly noticeable. The 7mm type 6 is an improvement. Also looked at Rigel and its companion, and M35. Seeing wasn't great and the breeze was annoying but it was fun never the less. Looking forward to trying it out on Jupiter later this spring.

That is one beautiful looking set-up!!  It's enough to get me buying scopes again!  Well, almost. undecided.gif

Looks like Atlanta did last year. This year has been one the coldest that I can remember.

That's sure is a beautiful telescope.

My very first Sky & Telescope is from 1967 I still have it.

What's interesting is I cut out the 'send for free catalog' from the Unitron ad, Edmund, and Jaegers.

A 4 inch refractor was and still is what I think is the ultimate instrument.

My driveway is about 1000 feet long and had 16” to 20” of snow covering it. Had the Polaris Ranger out for hours trying to get it plowed......oh, and a snow shovel for the places the Polaris doesn’t work. Not sure which I used more. I’ll ask my back in the morning.

Wo bet you miss Long Beach right now!  Is this something you'll have to take into consideration when building your observatory?

 

BTW, Today I mailed the lady that I bought the Unitron from some $$ for packing and shipping the 220 camera. . Hopefully I'll have It next week.

I completely agree! A 4” refractor truly hits the sweet spot! Still portable but show a lot with nice detail. I’ll just take mine shorter these days! wink.gif

Glad you were able to get the Unitron camera. I once owned one and it was really cool. Sold it unused however as the sheet film/plate thing was too much to deal with.

 

Yes on the snow here impacting the observatory. Anything you build here had to take snow and winds into account but lots of folks across the country have much the same. 

 

Miss So Cal? I miss the “seeing”. In So Cal almost every day was “70 degrees and sunny” which I found monotonous. Plus, everything I enjoyed doing required a drive through LA traffic. Congestion, noise, crappy air, chemically treated drinking water. Crime. Maybe a couple hundred stars visible on a good night. Skiing there became such a pain in the butt I stopped years ago. After cleaning up the driveways this morning I am putting on my skis, stepping off the porch and skiing the loop around the Deschutes and Twin Bridges. I may even take my fishing gear and fish from skis. Crystal clear and clean air, pure water, no crowds or traffic. And, if the next storm moves through in a day or two, there will be clear views on the Milky Way.

Well, I still haven't received the camera despite sending $50 for shipping. The lady doesn't reply to my text asking if the camera had shipped. Hope she's alright.

Looks like I'll probably need to sell this scope anyways. Once again medication costs are an issue. It never fails that just when things seem to be under control, they make some changes and back to square one. In my condition, its like adding insult to injury!

I found a nice Unihex at a decent price so I went ahead and bought it. I might buy an eyepiece set if they're in nice shape and a good price...The tray I will have to make and rig up a drive if I could figure out what the RPM's are.

These are nice drives. I used to have one.

You want that eyepiece set in the larger  or smaller eyepiece box?  Do you need slanted or straight letters? Do you want the 40mm mono eyepiece.  

 

All things you need to spec out.

I may have to take a drive in the Vette with all the fancy toys you have now. From the Unitron to the 7" AP i would be in dream scope heaven.

You've had some dream scopes yourself but you've sold them all.frown.gif  You probably had over 100K  in dream cars and sold them all too.frown.gif   I wonder if you enjoy the purchase more than the productquestion.gif

Sometimes the desire for an item is greater than actually owning it.  My desire for aperture thought me a lesson that bigger does not mean better.  Well, if you want to pay the cost bigger can be better, but everything comes with compromises.

It keeps my mind busy i guess. Without scopes and cars i would have nothing to think about. I don't have kids or a fam so  not much left for me. I just love trying news kinds of scopes and mounts.

Any luck finding that tray you need.  Might try my  hand at casting aluminum.    I have the tray to make the mold from.   All I need to do is melt some aluminum and pour it into the mold.   I learned how to do this when I was a teenager.
