Just looks at those secondary vanes !!!    

What type of diffraction pattern will those give ??

The idea is that spikes are canceled out.  In reality they show weaker, more spread, but less visible spikes

Looks like one of the TS 70mm F6 doublets from about 5 years or so back.  Probably a FPL-51 model, but thats a guess, do you know the aperture at least?

More like a 100 mm.  The finder scope is  40-50 mm

The only thing that can happen is that the images are upside down. But can easily be adjusted with software. But serious, you can think of going one size up in screw thread (and make a new thread) or just mount the dovetail, like you asked, on top.

Could it be your polar scope need some calibration?

Its probably a great way to love that little japanese even more. The next big question is: how soon will you put that TS thing for sale?

I think its the best approach for everything.   When your equipment lets you down or asks for a long preperation time, you probably dont use it as much as you want. 

Maybe they swapped the airco for a different more compact model between photos?

This indeed means clouds until 2024

Dont do it

Heey you have one of these rare tubes where the placed the logo after Celestron instead of at the beginning 

The dec/deck/top is gonna help me a lot.  Ra  will automatically be the other one

Yes that will work.   My initial clamp idea was more a solid or flexible metal clamp.  
For £1,- they sell these for example:

With a soft rubber protection

Nice dob.  The one thing thats missing is an unboxing of the 16” model

One of my first refractors was a 71 mm.  Bought an 80 mm and knew immediately the 71 wouldn’t get much use in the future.    Bought a 100 ed and the 80 was sold.  Bought a 120 ed and again knew for sure the 100 was going to be sold. All ed’s so comparable classes.   I cant share an experience when up-or downgrading to achro or triplet but for me the choice was clear.   The larger showed the most/best views visual.  
 

for Astrophotography i think a smaller apo is fine.  Like your Zenithstar for example

This Altair is 1300eur with the the reducer kit.

Brand new but not from an astroshop so no warranty which bothers me a bit.

We are really not interested in that source. Nobody wants to know where to buy telescopes for 60% of the regular price.😉

These rings will definitely be sold in a metal.  I can check a Dutch catalog if you cant find it in the uk

While the price of the asi2600 reach almost the asi6200 today here in Europe, im wondering which telescope you successfully use in combination with a full frame sensor   
 

Im considering an edge11 but curious which telescopes really work with a full frame sensor without problems   

Thats why, always buy at

Which version? The Altair.

Yes sorry.  That a difficult one.   The Altair is €2400 shipped to Europe.  The other brands €1400,-   

Altair is the best looking and focussing probably….

For €2400,- i would go for a feathertouched Technosky over the Altair

There was a member who bought the Altair a few weeks ago, maybe he can review the focuser?

Just pull the trigger.  We only live once

I dont own a tak but I would never think about a baader or v-power on that scope.  

Ive had 2 V power 2” focusers. One used and one new.   Both were just not it.  Forget them please. They are nice for a newtonian with 10 kg of cameras attached because they are very solid.  But smooth operation is not part of their features 

You could also shop for those that fix a bit more than the flatheads:

Lol.  This is the greatest hoax of 21, or… ?

I sold mine last year for €650.   But that was before all prices exploded.  I think an 100ed/equinox can sell for € 750,- easy in Europe   With flattener etc close to €1000,-

the same for the mount i guess
