Hello everyone,
I recently bought a set of Baader LRGB + f/3 3.5/4nm SHO filters for my Epsilon 160ED
Unfortunately, some of the filters produce halos, so I will be returning the set.
I would like to buy a different set of filters instead.
I don't want to go with Chroma or Astronomik.
The price is to high at the moment.
At the moment, I am interested in the following filters:
Antlia 3nm highspeed
Antlia 6nm highspeed
Antlia 4.5nm
Antlia 7nm
I have had good experiences with Antlia filters in the past, which is why they are currently at the top of my list.
Ideally, I would like to go with something relatively narrow, such as the 4.5 nm or 3 nm Highspeed filters.
Now to my two main questions:
I image under Bortle 7–8 skies.
Does it make sense to use, for example, the 6nm or 7nm filters under these conditions?
When imaging under very dark skies, many astrophotographers seem to prefer somewhat broader filters rather than extremely narrow ones.
However, I assume that under Bortle 7–8 skies I would benefit more from narrower filters such as the 3nm or 4.5nm SHO filters.
Or how do you see it?
Which filters would you choose for the Epsilon 160? Are there any others I might have overlooked?
Unfortunately, there isn't a lot of information available about the 3nm or 6nm highspeed filters.
The images I have seen look very good so far, assuming they haven't been heavily processed or selectively edited.
The 4.5nm filters also seem to be very popular, and one advantage is that they can also be used with slower telescopes.
However, I have read quite a few times that while they work reasonably well with fast telescopes, the dedicated highspeed filters can still provide noticeably better results.
I would be very interested to hear your opinions and, especially, your personal experiences with these filters.
Best regards,
Brian
