I just received my first AP setup (ES80mm FCD100 & EQ6-R Pro). I own both a D5100 and a D7100 and could use either but I know that the D7100 has a Toshiba sensor which can cause some less-than-perfect results in AP. The sensor on the D5100 is Sony I believe. Just looking at it, I think that the 5100 would probably perform better but would require an additional cable to be able to run on BYN. This additional cable would take me past the number of usb ports on my laptop and require me to figure out a 12v d/c USB hub (that's for another thread).

 

I guess my question is: will the d5100 provide better enough shots to justify the extra hassle of the additional cable and setting up of a usb hub?

 

I would love to hear any thoughts.

I use the D7100 and am happy with my images. I would suggest taking 20 manual shots (not using BYN) of some easy target with each camera, stack them and see which one does a better just. If you do this I would be interested in your compare analysis.

Oh hey, it's you again! wink.gif  Thanks for the advice on the Orion reducer. I picked up a used one from OPT for 90 bucks and it works perfectly!

 

As soon as I get all set up, I was definitely planning on conducting a bit of a trial with both cameras!

Sweet, glad the reducer worked out. I think you will find out both cameras are excellent. Good Luck

Just a quick update to all of this, I just sold my d5100 and kit lenses (I never used them anyway) and purchased a d5300 body. I will still test against the d7100 when I get a chance!

Don't even bother trying to use the D7100 for AP. The fixed pattern noise in the odd-ball Toshiba sensor Nikon used in the D7100 caused it to be a total "lemon" in their normally stand out lineup.

I've owned both a D5300 4yrs and a D7100 for 6 yrs, and my D7100 has never been used for DSO AP since I bought the D5300. The D7100 is a good daylight camera, but is absolutely horrid for AP....

The D5100 is equally as good, if not better than the D5300, if you do the "Black Point Hack", but is much harder to use in practical terms as it requires a separate d-sub cable that is very expensive, vs the simple USB connection of the D5300.
