NEW Skylight F15 refractor
      #5592264 - 12/28/12 08:34 AM

Hi group,

Richard has just posted news of a new Skylight F15 he will be launching at Astrofest in London February.

I was lucky enough to have one of the original F15's on loan from Richard to try out. By the time I made my mind up to buy one they were no longer available. I didn't want to go for the F13 despite it having an excellent Carton objective. I really wanted an F15.

I have my tickets ready for Astrofest so will be straight up the stairs on the Friday morning to take some pictures which I will try and post here when I get home on the Saturday evening.

Any guesses as to what innovations Richard may be including in the new model? Richard has said that it will be a 4". Given that he only makes his telescopes in small batches I won't be hanging about this time!

Hope you all had a great Christmas, ate too much and didn't over-exercise


Ian

Beautiful scopes. I wish I could get a brass dew-shield like theirs for my ED100.

Why not contact Richard to see if he can supply one?

Richard sometimes does custom work so it's always worth contacting him to see if he's able to help.

As for the new 4" f/15,I've no idea but it's very exciting waiting to find out.
One thing is for certain,the scope itself will look fantastic,all his telescopes are beautiful.
I'm sure most of the anticipation is going to be on the new lens though.

Mr. Onions, Lines of communication are open, negotiations have started.... watch this space. I have just been looking at the photos of your F15 mini you posted and it really looks the part on that Tele-Vue mount. Have you used it on Jupiter recently? I remember seeing my first shadow transit with a long focus 60mm refractor.

Ian,I have used the f/15M on Jupiter but not from a decent observing site as I need a bit more rugged mount for the long tube and I haven't had the chance to take it to my outreach spot as the it's been very windy,it's teaming down as I type.
However I have used it do great effect on the moon and it's a stunner!

Ian

I did a drawing of Io and its shadow transiting the SEB on Jupiter on the night of 09/12/2012 using my 8" F4.5 Dob. For comparison I also set up my 60mm Skylight F15 (F16.7). Io and its shadow were visible for the complete transit in the 8" dob. In the 60mm Skylight the shadow was also visible for the complete transit. Io was a little bit more difficult, being clearly visible when near the limb of Jupiter and just visible when nearing the meridian. Having the 8" along side did help.

On the following night when the GRS was visible I set up the 60mm Skylight along side a 120mm F5 achro. The 120mm as expected showed loads of colour but had the greater resolution. Interestingly, although the GRS was easier to see in the 120mm, it did not show some white ovals that I could clearly see on the southern edge of the NEB with the 60mm Skylight.

No no no Kevin.
You're wasting your time with your "poor" choice "one hour" telescope.
60mm..."Hey, nice finder"
For the benefit of some this is called sarcasm at the "so called" telescope experts who belittle 60mm size apertures.

As for Richard's new lens I can confirm it's a "Brass Triplet" yes,the lens is made of brass.

I thought a singlet lens of brass at F15 would be enough to give a colour free image. Think of the dark sky background and no need to baffle the tube. Safe solar viewing as well, Richard thinks of everything....

I can confirm that my experiments with transparent brass have been disappointingly unsuccessful...

I have it on very good authority that the new lens is an exotic brew extracted from an unknown mineral found in moon rocks. Richard forges it in a monstrous cast iron kettle heated over a huge open flame that burns in a deep pit carved into the ground on the site of the old forty inch Herschel telescope. The best lenses were made from the glass that bubbled out of that vaporous concoction on Halloween night.

The only potential down side to the new lens is that if you point it at the moon, the whole scope will dance and quiver when it sees its relatives. You might want to use low magnification for that view.

Kevin, Thanks for your interesting observation of Jupiter. I was very interested in the comparisons with the 60mm and your other telescopes. I know that the 120mm refractor and 8" reflector can show more detail but I have always found the purity of image in small long focus achromats the most satisfying. I remember comparing a 4" achromat with 10" reflector and althought the 10" showed a much brighter image with more detail it was really surprising how well the little refractor performed.

Hi Ian

Here are two drawings of Mars with the 60mm Skylight.

Hi Kevin, wow, those remind me very much of the view I had many years ago through a little 2 3/4" Dollond refractor which was f18. You were viewing it at a smaller disc size though. I have always been surprised at how easy the polar cap can be to see in a small telescope. The real test of the worth of a telescope comes in spotting the other markings. Great drawings and keep up the good work.

No more news on the new f15 then? I have been watching Richard's web site and Yahoo group but no new details yet.

Ian

Hi Ian

I am sure the new f15 will be nice, but I won't be buying one. Why? Because I already have one of the original 100mm f15s. The last one I think.
