Highpoint Scientific currently has 11in RASA for 25% off, OTA only or with a CGX or CGX-L.

 

OTA goes from $3600 to $2500.

Is it an open box, used scope?

From the email:

 

"For a limited time only, save $900 on the Celestron RASA 11" astrophotography telescope! We're making way for the RASA V2 (which includes a new focusing system), but here’s the thing: The majority of RASA 11 users add motorized focus to their system, and the Feather Touch focuser, which is included with the RASA 11 V1, is a great base for that popular upgrade. When you factor in a savings of $900, we think you’ll agree this is a seriously great deal!"

I think the newer focusing system includes a ball bearing mounted mirror which is definitely worth having imho.

No, they are new. The v2 RASA was released with the new focusing system, so it seems they are slashing the v1 price to get rid of them.

According to the Celestron website the new V2 does include the same ball bearing focus mech as the RASA 8 -- however, the RASA 11 V2 returns to the single-speed Celestron focus knob -- the Feather Touch duel-speed focus knob is gone.

Is the new V2's focus mechanism better? Sure. Is it "worth" $900 to $1,000 (discount on RASA 11 + mount) that High Point is offering? That $900 could go into a better camera - or filters, or....

 

This is a very tempting deal, but there are probably only a few available.

My C8 RASA is one speed also.  Since the spacing requirement on a RASA is precise, you need very little travel, and the one speed is geared way down, it's the equivalent of "slow" on a two speed.  Might be slower.  Works great, especially with the Celestron motor.

I'm not exactly familiar with all the differences between the one on sale and the newer one - but I did find this:

 

V1: https://www.highpoin...-1100-ota-91075

"the Schmidt Astrograph offers a full 70 mm optimized image circle"

Focal Ratio: f/2.22

 

 

V2: https://www.celestro...rograph-rasa-11

43.3 mm optimized image circle maintains pinpoint stars to the far corners of even the largest astroimaging sensors, while the usable field extends even further to 52 mm for larger format sensors.

Focal Ratio f/2.2

 

They both seem to share the same 620mm focal length, central obstruction diameter, etc.

Celestron builds it...they should know. In general specifications in retailers descriptions are notoriously unreliable. (personal experience) 

 

The RASA 36 (aka 14”) has a 60mm image circle (from Celestron ).

The optics are the same for both V1 and V2 and both have a 43.3 mm optimized field and a max 52 mm field with vignetting. The 70mm image circle spec was an error in Celestron's original published specs for the RASA 11 that persisted even on Celestron's website for quite some time before finally being corrected --- and apparently has still not been updated on some dealer's websites.

Celestron has said they are bringing the better focuser in the 8” RASA to the 11”. I would not expect a change in optics.

Fair Enough.

 

I'm really torn. I think I would like the upgrade, but If I instead buy an $1800 non-HD C11, and add the hyperstar for $1200, then I get a dual-use scope.

Well, the deal is too good to pass up for me.

I've seen a lot of images from the RASA 11.  They all look great, so I think the original focuser isn't a big problem.  

The Rasa 11 is selling out fast, I found one at the 3rd site I visited, so it looks like a lot of astrophotographers are picking them up at this price.
