What adapter should i get to connect my DSLR to a reflector.

Recommended Posts

Hello, i got my Cannon 750D few days, and im thinking of buying some adapters so i can connect it to my telescope. Will a T2/1.25 eyepiece projection adapter and a T2/EOS adapter enable me to connect the 2 together? Also im wondering why a piece of plastic and some metal is so expensive :)))).       -Ahgi, Clear skies!

Just get one of these, https://www.harrisontelescopes.co.uk/acatalog/canon-eos-t-ring.html

and then one of these to screw into it https://www.harrisontelescopes.co.uk/acatalog/t-adaptor-1.25.html#SID=26

personally i would not bother with the eyepiece projection adapter,

Yep..............these will work just fine.

Agree with the above, eyepiece projection is completely dependent on the eyepiece.

What scope do you have? Most Newtonians above a certain F-ratio don't have enough inward focus travel to focus for a DSLR in prime focus. If that is the case then you can attach a Barlow to extend the focus point, or move the mirror up the tube to reduce the focal length.

HTH

Edit: Never mind, I just realized that your signature says you have an Astromaster 130. You should have no problems with focusing as it is f/5. :icon_biggrin:

I do have a barlow lense just in case things don't go as planned and i can't focus, but is not having an eyepiece gonna reduce my magnification power compared to what i can see with my eyepieces normally? I want to do mostly planetary since my motor drive broke.

If your going to be doing lunar and planetary work then prime focus should still be the way to go. Add the Barlow in and shoot video using the movie crop function, stack in a stacking program and you should be good. Of course things get more in depth and frustrating then that, but that is the basics.

So, for prime focus, i didn't find T adapters, only T2, will that work? A T2-EOS adapter, and a T2-1.25.

I don't know what a T2 is? The two links that @JemC gave you should work fine with your camera.

if that is the supplier you are going to use then do not get the one you linked to,
get one of these https://www.omegon.eu/t2-rings/omegon-t2-ring-canon-eos/p,2416#tab_bar_1_select

and one of these https://www.omegon.eu/other-adapters/omegon-t-2-to-1-25-nosepiece/p,33230#tab_bar_1_select

and you should be good to go,

Regards

That is not the right adapter for prime focus. I assume that is for attaching 2" eyepieces in a 1.25" focuser.

well, the EOS adapter is for T2 as well, and the other one is T2, 1.25, so i don't see what the diffrence is, it's just a diffrent type of connection, the camera still gets connected to the telescope one way or another.

      Hiya, have absolutely no idea where to begin finding a camera for Astrophotography. And by that I mean - I know I want a canon but am unsure which to buy. It will be a second hand one. Does it need to be full frame ? Can any and all models be modified ? Is a higher pixel count the way to go ? What are the important things to look for in a DSLR ?
      any help would be great.
      Thanks
      Neil

      Good day,
      I own a  skywatcher Heq5 pro mount, its awesome!
      I just realized the AC wire for my AC / DC adapter is broken (see pic 1). I found another AC wire from an old AC adapter and was wondering if this is ok?  I see the gauge wire is bigger  though and wonder if it matters?
      I am thinking of cutting near the female adapter and soldering it back to the entire length of wire that came from the laptop adapter even though the gauge is bigger. ( see pic 2).
      Thank you.

      Back in early Feb I tried imaging Markarian's Chain, but after 2 subs I encountered guiding issues (a first for me) so had to give up. 
      So just for kicks and giggles, I decided to process them! ? 
      So this is 2 x 10mins. With the D5300, 80ED and HEQ5-Pro. 'Stacked' (if it's even right to use that term!) in APP, and processed in PS. Then reduced to 75% for posting. 
      Why oh why oh why..... I honestly don't even know myself ?

      I know DSLRs are more for “official” AP imaging and I should probably stick with my trusty ASI224 or maybe think about a 294 or similar sensors but....as probably many, I have a DSLR sitting at home not doing much. Can I do EAA with it?
       
      Today is quite easy to have 24Mp in relativity cheap bodies so why not to use it somehow? Small pixels..I know, but maybe going for wide field and bright objects with fast lenses it may still work and give something interesting. Anyone tried? Any experience? 
       
      What I really like of EAA is the ability to do everything while observing and without the need to come back for long processing sessions. I have searched around a bit but I can’t find a stacking software like Sharpcap for DSLR doing live viewing as well as stacking. I think I could somehow save each frame in a folder and then stack them with DSS (if I got the name right) but can I then control remotely the camera, exposition and have live preview when slewing around?
       
      Just interested to know if anyone know more about this or more in general discuss about DSLR and EAA.

      Hi guys
      I'm breaking the cardinal rule here of posting late at night, right after finishing PP, so let's see what sense the dawn brings! ? 
      I shot this in the early hrs of 29th of March. There was no moon present (i think!) and conditions were pretty good, AFAIK. 
      This is 28 x 360s, so about 2.75 hrs in total. Taken as usual with the D5300, IDAS-D1, and SW 80ED. 
      APP used for stacking and gradient reduction, everything else done in PS. 
      Would have liked twice, or 3 times, the data, but it's just not happening, so i've just decided to process what i've got. 
      Thanks for looking, and all CC welcome as always ?
