hi all just a quickie on the above when using this combo i have to crop heavily on say orion nebula,which i suppose causes a loss in quality,can i get closer(larger image) with this set up if that makes sense so i dont have to crop as much,before crop above

 

after crop

if you want to get closer you will need to increase the focal length of your telescope . This field of view calculator should give you an idea of the focal length needed. The D750 isn't listed but you should be able to find out the sensor's resolution and pixel size. https://photographylife.com/nikon-d750-vs-d810
