Jack and Chris, can you post the description for NGC1750?

 

I checked Dr. Corwin's NGC/IC data base and it, somewhat, indicates it being


a subgroup of the larger NGC1746.

 

I have another scatter brain idea.  Can some of you post your H400 

observation of NGC1750?  Here's mine from 1992 - "8" f6; at 60X 5' 10* 

9...12m part of NGC1746; field is NGC7146."

 

Thanks and clear skies,

aj
