Product Info

Manufacturer Description

1.25" Vernonscope Mounted Glass Filters feature 1" clear-aperture optical glass. Numbers are engraved on the mounting to correspond with those of Kodak Wratten series. The mountings are edge-knurled and threaded to fit the bases of BRANDON oculars and DAKIN Barlows. Vernonscope Mounted Glass Filters cut glare, provide superior contrast, improve definition and reduce eye fatigue.

Uses:

  • The magenta filter (#30) is excellent for use in observing Mars. It enhances red features and darkens green features..
  • For Jupiter observing, it is used to enhance white features.
  • Using a #30 filter with Saturn will highlight the rings.
  • For Uranus and Neptune, it is used to enhance the blue-green of the atmosphere.

Important Note: Brandon filters use a non-standard filter thread that works only with Brandon eyepieces and Dakin barlows. These filters cannot directly be used with other products that use the industry standard 1.25" filter thread (M28.5x0.6). An optional adapter (part # 114ADAPTVERN) is sold separately that allows you to use this filter on other accessories with standard 1.25" filter threads.

      4.0 A Nice Light-Magenta Filter

      Pros:

      Cons:

      Comments:

      I patiently awaited to hear from Agena when they had these back in stock, as they are often "Out Of Stock." But Agena surprised me - as usual. I got an email within a month - in this, a year with of noteworthy Martian Opposition fast approaching. And the #30 Magenta being a well-known Mars-Filter for such events.

      All in all, it looks and looks quite good. I'm not jumping for joy, but that due to any fault of the Brandon. It's that I'm a true 'Filter-Nut' and it's but one very nice "tool in the shed!" Many other's for me to test this year, too, such as a few FL-D filters and some commercial products as well. One qualm with this, Brandon? Please don't polish the outer metal-rings so much. You have made them literally slippery! The filter has flown out from between my fingers several times now!

      I searched far and wide for a magenta filter, and was so pleased to see that my favorite supplier, Agena Astro, has these in stock. Convenient one-stop source for this quality product!

      4.0 An Excellent Mars Filter!

      Pros:

      Cons:

      Comments:

      The Wratten #30 (magenta) filter can be considered a "minus green" filter, in that it passes reds and blues, but not very much green. Although Mars only appears close to Earth every two years, this filter will enhance red and blue features and darken green ones, as well as improve polar region features and some Martian clouds. This filter is my favorite filter for our red planet, and it has much less light scatter than the "Mars Filter" sold by another major astronomy distributor. On occasion I have also used it on our Moon, and it helped a little in discerning details. And on Jupiter it helps to bring out small white areas.

      Unfortunately, the #30 magenta filter is ONLY made for a one series of 1.25-inch eyepieces, specifically Veronscope/Brandon eyepieces only (hence 4 stars instead of 5). However, a simple solution is to get a thread adapter ring that Agena also sells (link => agenaastro.com/vernonscope-1-25-filter-adapter-for-brandon-eyepiece-4798.html), which will allow it to fit onto most any other 1.25-inch nosepiece. If fact, if the filter glass is unscrewed from the non-standard housing, and then placed into the adapter ring and secured with the retaining ring from the non-standard housing, then this useful filter can be threaded into a standard filter slide/wheel.
