The weather has been so bad I have had the time to finish a video on using astro filters with the Nikon Z bodies and Nikon camera lenses. There is a manual alternative to the FTZ allowing 1.25 inch filters to be fitted between camera and F-mount lenses, and for some lenses and end of lens solution make sense. FAstroTZ is described here:
I'm working with some recent data of a new(ish) camera, and my Ha data is pretty good, but the oiii has these strange artifacts around the borders.
If I use any kind of local normalization then it pretty much ruins most of the image, as you can see below..
First the Ha:
Oiii with local normalization:
oiii local normalization map, see how it fits with the artifacts:
Oiii without any local normalization:
These edge artifacts, could they be related to a bad filter or is it a processing artifact, has anyone seen anything similar?
I am using Astro Pixel Processor for calibration and stacking.. Im kind of stumped on this one, and I am going to yank out the Oiii filter this weekend to have a looksie.

Following a filter size upgrade I have an Astronomik LRGB set of filters, 1 1/4 inch. Probably around 12 years old. Kept in a filterwheel when in use but they have also been stored for a couple of years in their original box when I acquired some Baader ones to match my Baader narrowband filters. No scratches or coating issues. I have tried to show this in the images attached.
Looking for £80 posted given their age.
I joined the forum to learn more about risks and success of filter removal for UV and IR photography.
Back in 2011, one of the group's members, was trying to do just that:
Unfortunately Stephen hasn't been active in the group since 2014, but the filter removal appears to have gone well (at least the S3 wasn't killed in the process).
I have the same exact camera and I'm looking forward to try the same exact procedure. Does anyone has any tips on how to do this successfully/safely?
Hi guys, its me kronos, and i am about to purchase a new a new filter for my 5” and 8” scopes. I cant decide wether to buy a UHC or an oiii filter.
my budget it 70euros max
And i have settled between the uhc explore scientific
or the oiii explore scientific.
i am open to other suggestions in this price range
i am keen to observing more deep sky objects with better detail
Whichever filter i wont buy now, i will buy a better one in the future(for example if i dont buy the uhc , i will buy an astronomic uhc in the future)
So far i have loved the views of m42 (i have observed many more objects)and now thats its fading into the suns glare, i m starting to find more and more objects.Hoping to observe the veil and the lagoon nebula as long as some planetaries and definetly globulars(which i ve heard that they dont take filters(am i correct?). I ve heard that the oiii enhances contrast and dims the object, but is the dimming worth the additional contrast from the uhc?
i havent yet observed my first planetary , but i am planning to soon.I m really excited to see one!
I will make another thread similar to this then,asking questions that may arise and reach a conclusion.
I wrote this thread to ask about your preferences with filters(oiii or uhc) and for advice on what i should buy according to the objects i want to view)
thanks, any advice will be useful.
