Using zoom with a dslr ? was created by daveg54
Guys,
Ive connected my dslr to my nexstar 8 se and get some great pics of the moon etc .... but for further away objects, is it possible to zoom using the camera and take an image of the zoomed item?

In other words when im using my eyepieces i get a closer image but when the camera is attached via T ting, its hard to see what your looking at as we have no use of an eyepiece?

Hope you follow?

Cheers
Dave G

What dslr have you got if you have a canon theirs
a crop mode that zooms in it goes 1080p 720p 480p
the crop then zoom.

Thks Gliese, yes ive a cannon 1100d, i use the 2 buttons at the top right to magnify x5 x10 etc but when i take the picture its the original view less the magnification ?

Can you tell me how to crop and zoom? Cheers Dave

Hi Dave. The simple answer is no and the advice I'd give if there is a "zoom" function on the DSLR is don't use it. True zoom is optical zoom not digital and you can only get optical zoom by adjusting the lens. Because your cam is attached to your scope (the lens) then its fixed and zoom is not possible. Digital zoom is just that, it's the same as zooming in on the image in photoshop. It will only degrade the image.
Hope this helps.
Post your pics up when you take em!

Thanks Frank !
I thought as much, as im able to crop and resize afterwards on the laptop which is a digital enhancement... not great quality!


Is there a gallery we can add photos too? Or can i just attach them to a thread/ post ? I think i read somewhere we cant attach photos to treads?

Thks Dave

I took this moon image Friday evening

Have the same problem with the 1100D and my Nexstar 4.

I turn the ISO up to max. then find a bright star near what i want to shoot. and use it to focus using live view on the DSLR.

Then try and take the shot.

Results... no great, but you have twice the aperture I have some maybe you can get better results.

I have been told that its easier to use eyepiece projection, you need an adapter the you lock onto the top of the eyepiece and then slot into the T2 connector on the DSLR. you should be taking what you see in the eyepiece.

here is a link to one

hope this helps.

Have not tried it myself yet, but spoke to a guy in the States who gets great shots from a Nexstar 4.

Cheers Dave,
Yes i came across one of these gadgets before and reckon this is the only option to see what we actually see in the eyepiece in a photo!

A digital enhancement with cropping just aint good enough! Like the weather ................. Havnt used my scope in days !
