Yes, I am already reading and searching about my next step. I want more for planetary imaging but unfortunately I have also limitations....I can see that many people suggest the Mak127 (f11.8, 1500mm) as a must have tube and in my case scenario seems legit (portable and I can still use my tripod and AzGti).

But are there any better alternatives? I can see for example Omegon Maksutov telescope Advanced MC 127/1900 OTA or TS Optics Cassegrain telescope C 154/1848 OTA or Bresser Maksutov telescope MC 127/1900 Messier OTA.

Experiences, suggestions?

With that price I could buy a second hand car not just a tube to photograph the moon :-)

I don't know who make the Omegon 127mm.

 

https://www.astrosho...ab_bar_1_select

 

My experience with the 90mm 'MightyMak' was not good. Although I doubt the 127mm and MightyMak have the same OEM.

You can't really go wrong with the Synta Mak's though IMO.

SW Skymax 150pro, a friend of mine (now sadly departed) had one, loved it. Planetary only guy.

That would be great (or the best) but this automatically indicates that I have to go for a new mount to. The tube only weights 5.6k and the AZ GTI can't handle it :-(

 I have the Orion Mak 150 and the az-gti head on a sturdy mount can handle  it. It's not 100% rock solid, but for visual observations it's manageable.

Hmmm interesting..The specification says only up to 5k but probably we are talking about a safety measurement . I am interested in imaging so I have to add more weight too.

 

PS. Great tripod!

PS. Great tripod! 

The az-gti is all-metal inside, so it can take much more abuse then specified, especially when the OTA length is reasonable, not causing too much leverage. Hovewer, it has the annoying shift/looseness in the alt movement due to gears being not tight.
For imaging though, you would definitely need a stronger mount, and a paralactic/equatorial  head, since the alt-az is moving in a rotary way that sort of excludes precise imaging.

So, Mak 150 and HEQ5 could be your way.

 

PS. Thank you - The tripod (pier) is adapted from my first telescope (AD 1993).

I forgot to ask you: Have you changed the clamp? As far as I can see at your pic this is not the supplied one correct?

ADM sells a proper clamp for the AZ-GTi. I have a Vixen-style clamp for the AZ-GTi, though I think ADM also sells a Losmandy version. There is quite a long thread regarding the AZ-GTi: 

https://www.cloudyni...oto-wifi-mount/

 

From that thread, you can get some ideas of what people have placed on that mount. I think you would be fine with a Celestron C6. It weighs about 3.6-3.7 kilos without diagonal or finder. Sky-Watcher sells it with the 127, which weighs about 4.4 kilos, so the mount should be capable of handling the weight of a C6. That would maximize your light grasp and keep the weight down. The SW 150 Maksutov weighs in at 6.4 kilos according to SW. I'm sure the mount can handle that weight relatively well for visual. Planetary imaging is a little different. While some shaking/instability might be okay for visual, for planetary imaging, manual focusing becomes a little more problematic when the mount is not up to the task. 

 

The small bore challenges (moon, Saturn, Jupiter, Mars I think) can give you an idea of what a 150mm can do:

Yes, this is the ADM clamp from FLO. Highly recommended!

Instead of the 6" MCT could try the C6, which is somewhat lighter and smaller

The truth is that I haven't thought about Celestron but this C6 (or Celestron 6SE Starbright XLT is it the same?) seems promising.

 

On the other hand, I've read that there are not so sharp as Skywatcher Skymax and needs collimation regularly so with those in mind the proposal is Skymax for planetary imaging.

Well, that are for the most "legends" as the variability between samples is much greater than difference between the designs.
As for the collimation, much depends on how rough are with your telescope: if use it mostly from home do not expect to have to collimate it too often. The good is that the task is actually easier than with Synta's MCTs

Yes we are mainly talking about backyard planetary imaging.

I can spot 2 "versions" of Skywatcher 127: Full black color & black-white. Are there any differences?

I doubt it, it's mainly marketing. The Orion Synta Mak's are a wine red colour.

 

sml_gallery_249298_5348_902355.jpg

 

The 127mm Orion Mak's are the same colour as my 90mm Mak below.

 

sml_gallery_249298_5348_56444.jpg

 

They're all Synta made.

That's good cause I have an ad in front of me for a 127mm at 180 GBP.... undecided.gif gve.gif

I have both the C6 XLT and a Sky-Watcher 127mm mak on a SW-AZ GTI mount - both are very nice scopes.  However, the 127 mm get the most use by far since it is so easy to set up and use.  You may get a larger scope some day but you may find that as I did, having a quality mid-size grab-and-go scope will be your daily workhorse.

 

Cleat skies,

Mike

I’ve had my Orion 127 Mak going in 18 years now. I like it so much I’m just thinking of upgrading the EQ3 mount to a beefier Go-To mount. It’s too cold out to manually be finding stuff. ;)

Every time I think of upgrading I’m reminded that I’d be looking for something in addition to and not to replace my 127. It’s a neat scope!

The polar vortex has hit all over. We usually eat our meals outside, but the temperature was 70° (21°C) this morning. We pretty much froze over breakfast.

 

If a person is serious about planetary photography, they are talking about significant outlays for a much larger scope and mount, and probably not a Maksutov. A 6-7" Mak is good for transporting and setting up, but a 5" would be better for moving around the yard.

Went out for a few minutes the other night to look at the moon. Clear skies but cold! Forgot to put the dew shield on. Immediately realized my mistake the second I brought it back into the house.
