Clean filters - Here is how I do!


Recommended Posts

Hi, I just published a video of how I am cleaning my filters - I thought I might do this while my telescope is back at service due to some kind of astigmatism.
How do you guys clean your filters? it seems that every dust particle finds it way to the filters just as you are done cleaning them, and to sit in a damp bathroom seems kind of a mess...

Anyway, here is the video :)

Brush off the rough muck with a camel hair brush and then clean them in a sink of luke-warm water with a few drops of washing up liquid and my fingers.  Final rinse in RO water and dry them off with a fresh 100% cotton wool ball (for each touch on the surface = new cotton wool ball).  There is no rocket science involved.

Filling a bathroom full of steam, then taking your optics in to clean / assemble is a great way of keeping dust out, just be sure all of the moisture in the air has cleared first.

It’s probably the closest you’ll get to a cleanroom at home.

I thought it was just me that did this...I have a wet room so no mats and I remove all the towels too and even wear one of the "clean room" all in ones with a plastic hat for good measure.

I might get one of these suits and have one at hand next time i clean my filter, usually once a year after the dark season has ended here in Sweden.
I have a guest bathroom which is "empty" so to speak...

Great advise!

Now that we all have face masks its worth wearing one when cleaning optics, its amazing how much moisture/droplets comes from your mouth and nose ..

      The Carina Nebula (NGC 3372) also known as the Grand Nebula, Great Nebula in Carina, or Eta Carinae Nebula, is a large complex area of bright and dark nebulosity in the constellation Carina.
      The nebula lies at an estimated distance between 6,500 and 10,000 light-years from Earth.
      This image was taken from my backyard in Bortle 4-5 skies through a 80mm refractor at F6.25 (500mm focal length) with a QHY268M camera through 7nm H-Alpha, SII and OIII filters.
      Total exposure time was 5 hour and 50 minutes. Subs captured were HII: 12x600s OIII: 2x600s & 4x900s SII: 10x900s @ HCG:62 on 18th May 2021.

      This is my first image created using my new camera.
      This is NGC3603 and NGC3576 (AKA The "Statue of Liberty" nebula), a massive H-Alpha region containing a very compact open cluster, located in the constellation "Carina" about 20,000LY away.
      I took this photo on multiple nights, between 7th - 17th May 2021. Imaged using a QHY268M attached to a 80mm f6.25 refractor on a equatorial mount.
      Total exposure time was 25 Hours and 35 minutes using 7nm HII, OIII and SII Narrowband filters... imaged from a bortle 4-5 semi rural sky.
       
      HII: 3x600s, 12x900s & 8x1200s subs
      OIII: 18x900s & 11x1800s subs
      SII: 21x900s, 2x1200s & 7x1800s @ HCG:62
