Still confused about Astrophotography do we use eyepieces and webcam lense or not?

Question

I am still confused about using a webcam in astrophotography. Do we have to use the eye piece intact and webcam lense intact while mounting the cam to the scope. Or do we have to remove the webcam lense and the eyepiece and expose the ccd directly to the light without using the eye piece.

I have heard different views on this topic I wish to know which one is correct, most of the websites claim to remove the eyepiece and the webcam lense before mounting and this makes sense to me but please confirm what is the correct method for mounting a webcam onto a newtonian scope for planatery astrophotography?

Kindly quote the website source as well if possible

thanks

Answer 1

Why not try both ways? Could have some interesting and unexpected results. Many great discoveries have been made in just such a way!

Answer 2

i understand out of your later positioned up that this is a 120mm f/5 refractor man made with assistance from Synta (even even with the actuality that it has yet another sort call on it). I examined 2 of those refractors and placed that they both suffered from intense chromatic and round aberration, so as that the weren't usable above about 100x. So a 6mm eyepiece devoid of Barlow or a 12mm eyepiece with 2x Barlow should be the better reduce on your scope. the common concept that refractors are good for planetary commentary is merely authentic for achromatic refractors of classic layout (f/15 focal ratio) and apochromatic refractors; this does no longer be conscious to the cutting-edge crop of short focal ratio chinese achromats, that are f/5 to f/9. A 6" f/8 reflector will truly outperform those on the planets. even with what some solutions say, a good high quality Barlow has little or no adverse result, and using a Barlow with an prolonged focal length eyepiece will in many situations provide you with extra eye relief and a extra tender view.

You can do it either way, but for planetary pictures the use of "eyepiece projection" gives you a much larger image to work with. Tons of relevant links here;
