Post Asking for telescope choice

Hi everyone,

I am new to here and astrophotography.
I put an order of ED80 previously but the delivery time postpone to next year, so I have to find other telescopes now.
I currently have an HEQ5 mount, and I use it for deep-sky photography and sometimes for planetary (because I live in Sydney downtown).
There are a few options I found (second hand or demo):
1. Skywatcher 150/750 single-speed focuser.
2. Skywatcher 130/650 dual-speed focuser.
3. Skywatcher 150mm Maksutov
4. Intes Micro Alters 150mm Maksutov (M603)

My ideal one is 150/750 dual-speed, but I could not find any! Not sure does 130/650 can satisfy both deep-sky and planetary photography.
I understand Maksutov is good for planetary, but it can be used for a few deep-sky photographies and it has better image quality for imaging, right? And I heard Intes Micro is the best Maksutov, but because it is an old telescope which is what I concern.

Anyone can give any suggestion in this case? Really appreciated!

Cheers,
Taylor

The Intes is an interesting addition to the list!

General advice is to throw the focal length into stellarium, along with the size of your sensor and see what sort of field of view you get with each.
The Intes is a Maksutov cassegrain and, like the skywatcher mak, is slow for DSO photography. The Intes maksutov-newtonians are faster and more suited to DSO. There is still one for sale here in the classifieds.

The maksutov OTAs have a correcting meniscus at the front of the OTA, where as with the newts you mention, you'll need a coma corrector to flatten the field. The Mak newt has the meniscus and is fast.

I have absolutely no idea about planetary, sorry.

If you want a budget all round scope for both DSO and Planetary imaging then a 150mm f5 or 150mm f6 newtonian reflector will sit on your HEQ5 mount and provide enough aperture and focal length to image most objects with good detail either with a DSLR or Astro CMOS camera
I used a 150mm f6 newt on a HEQ5 and DSLR in Sydney for 3 years and only a 4 months ago progressed to a ZWO cooled OSC camera
Here’s some images taken in Sydney ( Bortle 7/8 zone ) with the 150mm f6 newt and my new ZWOASI2600MC camera
The planetary images were captured with my 10 year old Canon 600D

Cheers
