I’ve own mechanical tuners and pressure tuners and, at least in my samples, the pressure tuner is better and shows less noticeable off-band areas. A pressure tuner is as easy to use as turning a knob.

 

Below is my old Solarscope SF70 filter (a excellent filter BTW) that sported a mechanical tuner on a Borg 77 and my current LUNT 100 with a pressure tuner.

I really want one of those babies. Are they safe on the eye in terms of radiation etc?

Of course.

 

People have been using such filters for decades. If they were not safe, a lot of people and manufacturers would be in serious trouble. Head over to the solar forum for more info.

I posted in this thread quite some time ago, time to update smile.gif

 

Big and little brothers on the CEM60 in the observatory...

William Optics GT71 triplet, William Optics ZS103 ED Doublet.  They play well together!

 

Now I just need to get the WO Guide61 in gold to make it all aesthetically perfect...

My new Antares 152/900 V3. Arrived two weeks ago, had it out a few times. Excellent build and very acceptable CA.

With such beautiful red refractors on display, I hope you don't mind me adding my William Optics ZenithStar ZS80FD 10-Year Anniversary Scope.

My 100mm f/13 Carton lens based refractor finished recently. Star tests are excellent with minimal CA and basically equal in-out of focus images. Lunar detail is stunning.

Thank you!  It started when I got hold of the objective lenses years ago. Then the telescope was built for them. The tube, objective cell holder and focuser are from Crawmach and it took a long time to get all these parts. It was assembled for optical testing but the cosmetics and other details were finished just last week. It is indeed a long cannon.

Good looking scope.  Love that natural finish.

OK, I've posted a picture of this refractor before, but I believe it was configured for imaging not for visual use.  In any event, what with the "shelter in place" order in the Bay Area and the persistent rain that keeps me from even going out into the back yard, I have very little to do at home but take pictures of my telescopes, yell at the kids, and tell the dog to be more patient--his dinner will come.

This refractor is a very well mounted beauty. Is it also a 100mm? It looks like an f/16 and permanently mounted as I would like to have mine someday.

 

Clear Skies!

And here is a pic I took with it the other day (just holding my iPhone up to the 5mm DeLite eyepiece).  Sea of Tranquility and the Ariadaeus Rille.  It was the latter that made me want to snap the picture.  The angle of the light must have been just right since I have never noticed this rille before, and it stood out quite starkly through the eyepiece.

Thanks.  Jaegers 4-1/8" f/15; 4" f/15.5 in the cell.  The finder is Jaegers 2" f/7.5.  Both have the same chromatic ratio.  The mount is permanently outdoors.  The refractor enjoys trips to and from the mount.  My favorite scope to observe with.

My newly arrived Stowaway finally made it to the side of its older brother https://www.astrobin...r6ca/I/?nc=user.  Mounted on the underside of the old Parallax rings of the 6" refractor:

Very impressive. One of the best iPhone images I have seen. 👍
