Hello,

 

I am looking into making the plunge into NV, and I am leaning toward the MOD3 C-mount setup because I have lots of Canon EF and FD lenses I can adapt.  I am curious why all the pictures of MOD3 units don't show the rubber eye cup like the PVS-14.  Is it a uniform eyecup or is there none?  Do I need one?

 

I'm in Bortle-7 North San Fernando Valley, Los Angeles.  There is lots of light trespass from a school across from me (they run security lights 24-7), but my backyard is somewhat shielded.

 

Thanks,

 

Todd

The Mod 3 comes with eye cup and I keep it on all the time - others users may remove cup for other reasons. 

 

You will need filters and 1.25" or 2" filter size up to you and if you are not sure, dig a little as there is a ton of info on this.

 

Strongly suggest you pickup the following (I live on east coast in B7 sky):

== Baader 685nm IR filter for good contrast in looking at clusters, galaxies and general gazing the sky

== Astronomik 6nm Ha CCD filter for views of emission nebula

 

Note: The Astronomik 642nm IR filter is great for looking at milky way clouds and some nebulosity is visible.

Mine has the eye cup. In general I don't use it unless there is a high chance of dew. I find it's best to use glasses when observing with night vision. That can still be done with the eye cup on, but it tends to leave marks on the glasses over time.

There is also the Optolong Night Sky H-Alpha Long Pass Filter (650nm) which I have.
