I wonder if the motors on the new mount are quieter and/or faster than what is on the ASGT mount...

Can't speak to the quiet part as they haven't started shipping. Max slew speed is 4°/sec, up from the 3°/sec of the CG-5.

Is that mean I do not need to do Polar Alignment?

We would assume that you would still have to do a polar alignment with a German equatorial mount if you wanted the mount to find and/or track anything. Altazimuth mounts (ike the CPC, CPC DX, NexStar SE, NexStar SLT, LCM, etc.) do not require polar alignment.

Attached is a pic of the StarSense.

Hmmm. This would seem to be getting into quite a bit of stuff plugged in if you want to guide and do starsense on a scope you're going to do AP on, then. Do you have any way of checking?

Is it possible to get a picture of the VX mount by itself with better lighting?

Quite a bit of new info.

Is the SkySense able to autoguide? If so, this is quite an announcement. I'd really like to see this sort of thing pan out.

-Rich

It is not an autoguider. It is simply designed to make alignment on the sky a no-hands three-minute automatic procedure.

I would love to see pictures of C-8 EdgeHD focal reducer.

Photos are not yet available, but here's a computer-generated rendering of what it will look like. Will put up an actual image when it becomes available.

Incidentally, the StarSense is available on our website for preorder under our part #CSTAR.

Products include an Advanced VX series of go-to scopes that will replace the current Advanced Series line. They use a completely reengineered version of the Advanced Series 30 pound payload capacity mount. It has permanent PEC, a wider latitude range, tracking past the meridian for imagers, improved electronics with All-Star polar alignment, a built-in autoguider port, new motors for better astrophotography tracking, and more. Scopes will include and 8” EdgeHD version, in addition to all of the current 6” to 11” models currently available. Prices run about $100 more than the Advanced Series.

Does that wider latitude range include 0 or 90 so it can be used in alt-az?

I've just tried it, the latitude scale range is 0 to 75 and it will adjust to just below 0 without hitting anything.

BUT it's never been mentioned that it will work in alt azm mode and there is currently no option to switch the HC to an AltAz mode.

An AltAz mode would need significantly different firmware because in previous mounts the hour angle axis is equivalent to azimuth and the dec to altitude. If the mount it set to zero latitude then the dec axis becomes equivalent to azimuth and the hour angle axis altitude, i.e. reversed.

I would assume that it is not a dual use mount unless Celestron says that it is.

Chris

PS it seems a bit quieter than the AS-GT but it's not silent.

Is the focal reducer at the CES show? If so, can anyone photograph it and post the photos here?

If it can physically do it, then Celestron would be foolish not to spend the time to give the software this capability, when they clearly already have this capability in other versions of their mounts, both dedicated alt-az such as Nexstar and dual-use such as CPC on a wedge or the new AZ-EQ6.

Are there any details of the FR? .7x reduction? Sensor spacing requirements?

and to really work you hard...

How about a pic of the OAG?

Thanks.

This FR is now at Celestron web site but no photos yet.

http://www.celestron.com/astronomy/edgehd-7x-reducer-lens-8-inch.html

It says 105mm back focus. I am not happy about this much shorter back focus than 133mm for F/10.

Here it is. The Celestron off-axis guider is compatible with all Celestron EdgeHD and SCT telescopes, plus imaging refractors and other telescopes. It has a high-quality helical focuser, adapters for several configurations, a 12.5mm multi-coated BaK-4 pickoff prism, 48mm clear aperture with full illumination for camera sensors up to 35mm, adjustable prism height, 360° independent camera and telescope rotation. It includes Off-Axis Guider body, male and female M42 T-threads, male and female M48 adapters, SCT/EdgeHD threaded adapter, 15mm M48 spacer, and 8mm, 15mm, and 30mm M42 spacers. Price is $249.95.

That's interesting. Their price list says $249.95. We're checking with Celestron to see which is correct.

The $249.95 price on the off-axis guider is correct and has been corrected on the Celestron website.

Look at all of the spacers and adapters for the OAG. It would cost you $100 to buy them alone. Seems like a good deal.

Thanks for the price update. The three thumbscrews at both sides of OAG looks like they are for securing Celestron dovetails adapters. It does not look like there are threads at each side of OAG. I think it allows you to rotate at both sides of OAG. That's fine, I am just trying to figure out how the OAG works. The Helical focused at the guide port is a nice feature.

Hi frebie,

Can you find out if the back focus distance for C-8 EdgeHD focal reducer is 105mm? I am hoping it's a typo. I was really hoping they would maintain the same back focus distance as for F/10 which is 133mm.

Celestron should know better that 105mm is too short for many imaging equipment. What about Adaptive Optics, rotator, etc? 105mm will not work with these equipment.

FR for C-11 and C-14 EdgeHD maintains the same back focus distance (146mm) as for F/10 and I thought that was a great idea. I assumed they would do the same thing for C-8 but they didn't.

I had to cancel the order for On-Axis Guider (ONAG) because ONAG will never meet the 105mm back focus. The absolute minimum with my equipment to work with ONAG is 115mm, but in reality, it would be more like 120mm. ONAG back focus is 66mm.

Peter
