Is there a 5-6" Mak or SCT with push-to capabilities?

Negative. Of course you can always purchase them separately. AYO Mount for around $900 with encoders, purchase OTA separately, then buy the computer. It will be a lot cheaper to get a GoTo model.

That is fully manual. He is looking for push to, like Intelliscope.

I assume that you mean mounted on a simple Alt-az mount without any kind of electronics.

 

This one comes on many different mount options, three of which are "push to."

And this one is the 6" version:

There are many 127 and 152mm MCTs on the market, and adding the Alt-az mount of your choice is easy to do, but if you are looking for a package, options are rather limited.

Hi you can mount your scope on a vixen porta  II,

Then check out post #58 here.

Shows making your own degree circle, and you can use a digital angle meter to get elevation.

There is a Skywatcher AZ-GTi package with a 127mm/5” Mak for $625 USD.

I guess I assumed the meaning of 'push to' was universally understood. Seems I was wrong. I want a computerized system that will guide me to the targets, but not with motorized drives. I provide the pushing, but a computer tells me where to go, like the Intelliscope series, but in a Mak or SCT.

A google search of “Skywatcher AZ-GTi 127mm” will get you what you need

This actually becomes more expensive.

You need:

1. A Mak or SCT
2. A mount that can be fitted with encoders for a DSC
3. A DSC like the Nexus DSC
4. An encoder kit for the mount

Astro Devices, maker of the Nexus DSC, has encoder kits for several manual alt/az mounts that run about $250 USD. This is the best option I have found for push to. As is the Nexus DSC. But together they will cost more than the Skywatcher 127mm Mak package and doesn’t include the scope or mount..,

Isn’t the AZ-GTI motorized/GoTo?

Push to is very popular with giant Dobs where motors would be heavy and cost prohibitive. The same technology is easily adapted to an alt az mount, and the high end mounts are designed for this. So what you are asking is routinely done, but you are talking expensive mounts and expensive push to systems, because none of this stuff is mass produced like an Intelliscope.

Is a 6" pushing it for the same mount?

AZ GTi is motorised/GOTO, but it also has encoders, so that when you loosen the clutches and move it manually it doesn't lose alignment, and has the advantage of allowing tracking after a manual move. 

This is unusual in lower priced mounts. 

 

Thus the OP could use it semi-manually.

If it is a Mak or SCT, no. People put a Takahashi FC100 refractor on it with zero problems. A 6” Mak or SCT will be fine as long as it is not a Comet Hunter or equally large Mak. The standard Skywatcher 6” Mak should be OK and the Celestron 6” SCT is as well.

As dr.who says, it should be OK - it has a nominal payload of 5kg.

A word of warning though - SkyWatcher also sell a mount called the AZ GTe - and this doesn't have the encoders.  

 

I've seen it bundled with a short refractor which looks initially like a great bargain, but I think the absence of the encoders is a significant downgrade in its capabilties

What you want then is a system with digital setting circles and that is something that I have not seen sold as a complete package with either a 5" or 6" MCT.

 

Maybe there is one out there, but if that is what you really have to have, then I think it is more likely that you would have to build up a mount and that can be quite expensive. 

 

If you really don't want motors though, that is a tight box and if you are willing to accept motors, then why not get Go2?

 

Perhaps you could get something like the Orion 6" Intelliscope table top reflector and put your own OTA on it. I an not recommending that you do that, but that would be maybe a cheaper way to do it than build up a system using a good Alt-az mount, encoders, and DSCs.

 

Anyway, so sorry, but I don't know of an offering that has this combo.

+1

 

I was literally typing that you could get the 6" intelliscope and swap OTA's when Eddgie's reply popped up. Same caveat: It's not what I would do, but if you are adamant on Push-To without motors, this would work.

 

Oh, and as far as I know, the AZ GTI mentioned above won't function like Push-To. It's not going to have arrows telling you where to push the OTA to get to an object.

You could simply purchase the Intelliscope 6" and stick with it (the 6" f/5 reflector provides more flexibility and will be much more comfortable to use).

Several mounts could be fitted with "digital setting circles" systems to become "push-to", but those systems are not exactly cheap (you need the computer, the encoders, and obviously the mount).

 

Also take note that the Skywatcher Mak6" is noticeably larger and heavier than the 5" model (in fact is more or less as big as the C8), and will not work on mounts as light as the Porta (which is the cheapest alt/az which could be fitted easily with "push to" systems); to tell the truth, I would suggest to stay away from the Porta even in the case you will opt for the 5" as the mount is rather marginal for it

The closest you can come to this is to buy the Mak or SCT on a good AltAz mount.

A unique feature of SkEye is that you can strap your phone to a telescope (or a pair of binoculars) to get a PUSHTO guide, without additional equipment! You only need to follow a simple alignment procedure. Find out more about it in the Documentation section.

I don't suppose there's an iOS variant of this? I dunno maybe I could buy a $100 android phone for this..

Larger version here with iPhone and SkySafari:

For a 6” you could use a smaller mount with encoders, that’s up to you. The AYO Swiss come to mind, or the Rowan Astro AZ100 (overkill). The Hercules is a possible candidate but you’ll have to speak to Astro Devices to find a solution for the encoders.
