I am a keen photographer and I'm wanting to buy my first telescope with the primary purpose being to take some moon photos.  My camera is full frame Canon EOS 6D (DSLR).

I have been recommended the Celestron Nexstar 5SE.  I am keen for help with the following two questions:

- What would be the benefits of 4SE vs 5SE vs 6SE vs 8SE?  The price jumps a lot from 4 to 5 and from 6 to 8.  What would I receive

- Is it easy to use and attach the camera?
- Are there any other options that I should consider?

(I'm not really wanting to go over £1,000 including all required adaptors, tripod, case, etc)

Thanks in advance

A 5SE will do the moon, it will have around a 1500mm focal length so the moon would be about a 13mm diameter image.

 

Now after that you are sort of stuck.

It is possibly too small for Mars and Saturn and Jupiter have basically disappeared.

So in a way you are buying a scope for one object only. You will lose a lot of friends when you show them your 20th image of the moon.

 

The scope is wrong for DSO's it is a long focal length, the mount is wrong for DSO's it is Alt/Az and for DSO's you need an equitorial.

 

Being honest you can get decent moon image with a fixed tripod, the camera and a 300 or 400mm "standard" lens. Set the metering to spot, ISO to 800 and push the button, or cable release.

 

If poor contrast then lower the ISO, upping the ISO makes the contrast lower.

 

Can I suggest you rethink your ambitions or directions.

Do not get the idea that AP is a scope and a camera, and so any scope and camera will in effect suffice.

Also remeber there are say 3 planets and a moon (if you are lucky) and there are several DSO's to image. And planetary imaging set up is not a DSO imaging setup.

 

Now this is personel opinion but I looked at an 8SE when initially looking at scopes and that was around 2000. The 8SE has not changed radically and 2000 was before DSLR were around and the idea of sticking one on the rear of the SE's was not a requirement or design factor. I don't think adding what amounts to around 1Kg to the end of the scopes is a good idea. A webcam yes, one of the planetary ZWO's as an example but not a DSLR.

 

Also you do know you take a video and stack the best frames from the video?

Moon is bright enough for a single shot but the good ones are from video capture.

 

Where did the advice come from?

I have an idea you are being sold, or directed to, a scope that would do The Moon, but not a lot else.

 

Add a location, I guess you are UK (£'s) and otherwise answers will be US orientated. They still will but maybe not quite as many.

What about a refractor , a skywatcher evostar 80 ed , this is the cheap package without the extras , great scope , no collimation and next to none cooling time.

this will keep you just below your budget.
