My new Stellarvue Raptor 90mm Triplet arrived today -- 2 days ahead of schedule. It's a beautiful instrument. Here are a few pics.

Just out of the box.

In the observatory ready for astrophotography.

According to the forecast it might even be clear enough tonight (partly cloudy at the moment) to take a look!

Thanks Stephen and Maxx. I was just out fighting the cloud gods to check out the new scope. A bit too much overcast, so about all I could say about Jupiter was that my SVR90T has that snap into focus that you see with a high quality scope. Hope it clears a bit more so that I can see some detail. It sure looks nice piggy-backed on my 190 Mak-Newt. Forecast is for clearing as the night goes on. Be patient...

Still waiting for first light with yours Maxx?

Congrats on your first light!

It did clear later in the evening but there was a strong wind so seeing was poor. Still, managed to grab some views of M45, M42 and Jupiter. Sharp, contrasty views. I also took a few test shots with the DSLR to check out spacing for the reducer/flattener - I can already tell this scope is a keeper - stars are sharp to the edge of an APS-C chip and very even illumination (the only reason to take flats is to catch dust motes, there is no vignetting at all that I can detect).

Congratulations on your new scope! These things are onyx jewels.

Since getting mine on 2/1, I have managed to get in a bit of casual stargazing every night save two.

Best,
David

Thanks David, Maxx, Scott, Jim. This is the first high-quality refractor that I've bought exclusively for imaging (others have been guiding/occasional wide-field scopes). I can't wait for some clear nights!

Good choice, I'm waiting on mine to arrive.

What kind of tripod is that in the picture?

The tripod is just a Manfrotto that I use for occasional visual, mostly with my Lunt 60 for catching solar views. The primary home of the SVR90T is in the observatory. Lots of happy SVR90T customers with the sale; you will love yours! It's worth the wait.

Congratulations on the scope. I have the same scope and love it. I see you have the TV 0.8X focal reducer as well. I have it too an it works really well with the Raptor.

Enjoy!

Thanks Bryan. George, I'm wondering if you ever tried experimenting with the spacing of the TRF-2008? I know that's hard with a DSLR since standard T-rings put the spacing at 55mm so you can only go longer. I read however that with CCD cameras shorter spacing worked better with the Raptor. I did find a solution for shortening the distance however. If you search on "Low Profile EOS T-ring" you can find one on eBay from the UK. I tried spacings of 55mm (standard T-ring), 52mm (low profile with spacer) and 45mm (low profile T-ring). To my surprize the 45mm spacing seems to give me the roundest stars right to the edge of the field. I have only had one chance to try this though. But 45mm is the spacing I'm going to experiment with further. The T-ring is well made and metal, but not black so I may have to watch for reflections. Still, I'm wondering if others have found such a close spacing (10mm less than recommended) to work well?

I have a favor to ask you, and have no problem if you don't want to or can't do it, but here goes...

If you have a green laser pointer I would like for you to shine it through the optical group and let us know if you can see the beam passing through all three elements.

Thanks a bunch if you can do it. No problem if you can't. I ask because green laser light passing through true CaF2 crystal does NOT scatter meaning that you can't see a green laser beam in true fluorite matrix. Low dispersion glasses do often use some CaF2 in the mix, but unlike CaF2, which is a homogeneous, uniform crystal, ED glass (even that matching closely the dispersion properties of fluorite crystal) always produces some internal scatter and will show the transit of a green laser beam.

It will in no way damage the optics.

Regards,

Jim

Jim, I'm game. I'll try to remember to do the green laser test on my SV90TBV fluorite one of these days (no time tonight) and get back to you on that. It should be interesting. Posted Image

Yeah, I'm going to do the same on my FS-78 this weekend and will report back.

Sounds good, Jim. If I forget, feel free to PM me this weekend to remind me. Anyone else with a fluorite (or presumed "fluorite") scope want to join in?

Jim, if that was directed at me, regrettably I don't have a green laser. It needs to be green?
