Best camera lens graduated color filters according to redditors

You need a 77mm adapter ring for example https://www.amazon.com/Cokin-BP400A77-Filter-Holder-Adapter/dp/B0010841A6/ref=sr_1_3?ie=UTF8&qid=1469629323&sr=8-3&keywords=77mm+cokin

Then you need the square filters that fit it such as this one for the example i showed you
https://www.amazon.com/Cokin-Graduated-Neutral-G2-SOFT-Filter/dp/B00004ZDB1/ref=pd_sim_421_4?ie=UTF8&dpID=31xFP81rz3L&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&psc=1&refRID=VH0M0F5GYF6NQ4DSTE86

An easy way to think about it is a piece of glass that sits in front of your lens that is dark at the top and gradually gets lighter to the bottom. This lowers the exposure of the sky while allowing the landscape to expose as normal.

I also came across this filter:
https://www.amazon.de/Gobe-ND1000-77mm-16-Schichten-Filter-black/dp/B01F1JJ1IG/ref=sr_1_fkmr3_1?ie=UTF8&qid=1539363437&sr=8-1-fkmr3&keywords=52mm%2Bnd%2Bfilter%2B10%2Bstops&th=1

Do you think this one is better?

Question on the filter photographing the solar eclipse. My dad purchased a Gobe ND1000 58mm MRC 16-Layer ND Filter for use on our Nikon d5300 with a Nikkor 70-300mm lens because in the answer section on Amazon the seller said it would work. After reading this thread I'm really having doubts about the filter. After reading we did purchase a Hoya Solas from B&H to stack on top of the Gobe. Will this be enough to protect the image sensor while taking pictures of the eclipse or did we waste money ? Also would a UV filter also need to be stack on ? Thanks

Hi everyone! I'm planning a trip to Norway in December and I needed some advice.

I will depart the 5th of december and return the 12th.

Here is what I'll bring with me:

• Tripod
  
• Nikon d7200
  
• 50mm Nikon lens
  
• 18-200mm Tamron lens
  
• Backpack
  
• ND filter
  
• and more things...
  
  My questions are: what lens should i buy in the list I wrote under this line? (I need the lens for astrophotography and norther lights)
  
  
• Tokina 11-16mm (bigger aperture but not sure...)
  
• I can't seem to link it for who knows why so here: Nikon 10-20mm ultrawide
  
  Second question: hould I bring something for the cold temperatures? What should I bring then?
  
  ​
  
  Thanks and sorry for any eventual error!
  
  Edit 1: the comment bugged out, it displays a point under this row that I can't delete...
  
  Edit 2: grammar nazi
  
  
• Nikon 10-20mm (smaller aperture but maybe better quality and less distorsion?)
