Hi,
I have the opportunity to travel next end of April to a Bortle 3 zone to spend two or three nights. Unfortunatly is time to galaxies and the targets for my Fsq106/Qhyccd 163mm are few.
I'm strongly consideration to mount my Nikon D850 unmodified with a 58mm f1.4 or 70-200 Vr2 f/2.8 to take wide field photos.
I would like to take RHO Ofiuco, even is low but is the only chance that I have.
Will I take something having four hours for example?
Which Iso is recommended?
Which lense will be more suitable?
70-200 vr2, 58 f1.4, 85mm 1.4?
Or forget it and try to choose a target with the Taka and Qhyccd?
The Location will be Teruel, Spain.
Thanks

You would have the Virgo galaxy cluster to shoot early with the FSQ106.

 

And then Rho Ophiuchus later in the night. 

 

The Rho area can be shot with a variety of lenses. The longest I would use would be the 200mm.  

 

But it will also frame nicely with the 85mm, and even the 58mm if you include the dark nebulae that run to the east.

 

On the D850, your exposures should run about 3 minutes at f/2.8 at ISO 800.

Thanks Jerrry!!

I appreciate your explanation and recommendations!

Just thinking to put the new Asi 2600 to those lenses, just an idea!

Just remember the ASI 2600 is APS-C, so it's going to frame differently than the D850 with the same lens.
