Telescope with GoTo recommendations

Astrophotography
#1

Hi,

I already own a 90/1000 mm refractor telescope, but since I am unable to take photos of deepsky objects, I am planning to buy a telescope along with a goto mount. I need some suggestions since right now I am going to buy this and In future I will be buying a camera to shoot astrophotography along with this setup. My total budget for the telescope and goto mount is around 50-60K. Can some please suggest me along with the details of where to buy them.

I am unable to take photos of deepsky objects, I am planning to buy a telescope along with a goto mount.

If you want to take photos of DSOs, you need an equatorial mount. You get both alt-az and equatorial with go-to but equatorial is needed to track dim DSOs for long exposures without resulting in field rotation.

My total budget for the telescope and goto mount is around 50-60K.

At this cost, I would recommend something like a star tracker. You can buy high quality lenses for your DSLR and take photos of nebulae and a few galaxies.

@siva can you suggest me one, or some second hand ones?

Sky-Watcher’s Star Adventurer and iOptron’s SkyGuider are easily available and widely used in India.

@siva I saw this in tejraj, is this worth it?

and let me know how to find prime focus of a telescope when a camera is connected, since the above have prime focal mirrors so what zoom can i expect?

@siva @Nanikutty can you guys check out the above message, let me know whether they are good or not for deep-sky beginners astrophotography?

@Bharathwaj_Elango sorry bro, I don’t know about a telescope.

I haven’t seen anyone use this telescope and mount combination so I cannot give the best feedback about this. However, looking at CloudyNights, I don’t get the best impression about this combo.

#9

@siva thank you, can you recommend me one then? And where to buy them? My budget is around 50-60k

Please see my earlier comment.

@siva what about using the same above mount with a william optics zs61 ii?

@siva also check this out and let me know for DSO astrophotography

Hi,
Did you get to figure out your choice of telescope and mount?
I’ve been away from the group for a while and I haven’t replied to your previous question in a different post.

The choice of telescope depends on what FOV you would like to image.

Close to above mentioned budget,
I’d aim something like this -

  1. Skywatcher star adventurer/ Ioptron tracker
  2. Rokinon 135/ Takumar lenses/ Askar 135/ Askar 180

I can personally vouch for Askar180.
Not the best l, but definitely does the job. Askar boasts that they are sextuplet telescopes with reducer, but there’s still CA. Here’s what I took with it -https://www.astrobin.com/fegk5j/

If you are looking longer FL, below is my recommendation

  1. Celestron AVX
  2. AT60ED
    But you’ll have a tough time finding them.
    Cloudynights is the best bet, but import/shipping is going to be a headache.
    Longer exposures/focal length are going to be less forgiving.

Hi the honoured one here,
Can I use azimuthal mount and auto guiding to get more time for the exposures
