The solar filter for the Omegon Basic telescope
You observe the night sky, but are you also interested in observing the Sun? The Basic solar filter lets you also do astronomy during the day! And the best part is that, if you have an Omegon Basic telescope, it fits directly onto the lens. And you can get started right away with your solar observing!
The advantages in a nutshell:
- attaches directly to your Omegon Basic (or similar model) telescope
- saves time - no tinkering or construction necessary
- exact matching plastic frame for many models
- made using high optical quality Baader Planetarium AstroSolar solar foil (filter factor ND5)
- inexpensive solar filter
Perfect fit with Omegon Basic
The Omegon Basic solar filter comes already assembled in a plastic frame. That means that you will not have to tinker around or construct anything. This filter makes it simplicity itself for you to use - just attach it to your Omegon Basic telescope and it already fits perfectly.
Solar filter foil for safe observing.
This solar filter is made using a special filter foil that provides you with a neutral white image of the Sun. With a filter factor of 100,000 times, only 0.001% of the sunlight entering the telescope reaches your eye, which means you can always observe the Sun in perfect safety.
For what and for whom is this solar filter suitable?
This filter is fantastic for when you want to observe sunspots and solar flares and also for observing granulation on the surface of the Sun. It is also great for observing solar eclipses - it is breath-taking watching the Moon gradually obscure the Sun's disc.
Photography using the solar filter!
The Sun always shows some exciting detail. Keep a record of the spots and flares with your camera and become a solar photographer. You can also keep track of how an entire sunspot group evolves. Nothing could be easier! By the way - the matching adapter for your particular telescope can be found in our accessories section.
This product allows you to perform safe observation of the sun. Here’s how:
- Partial solar eclipse: The moon has not yet completely covered the sun. During this time, you must keep the Filter or protective cover fitted!
- Total solar eclipse:* Once the last of the sunlight has disappeared from the edge of the Moon (“diamond ring”), the filter may be removed. The total phase is brief: just a few minutes. Enjoy it, but remain vigilant: when the “diamond ring” reappears behind the Moon, put the filter back on the telescope or binoculars!
- The same applies to solar observation glasses (special protective glasses for solar observation): during the partial phase, only look at the Sun through these glasses; during the total phase, remove the solar observation glasses.
* Many solar eclipses are only partial. In that case, the protection naturally remains on your telescope or your nose the whole time.
Our expert comment:
Will this solar filter fit my telescope?
You can find out quickly and easily which solar filter fits your telescope: Open the Solar Filter Table. Here you can see which filter fits which Omegon Basic telescope.
If you are using a different telescope, it is best to refer to the ‘Telescope front Diameter’ column. Here you can see what the outer diameter of your telescope must be for the Filter to fit.
- The colour green means: The filter fits perfectly
- The colour yellow means: The Filter fits, but you should stick a thin strip of foam in place.
Even with a filter that fits exactly, it’s best to err on the side of caution:
- Check whether the solar filter might come loose. Give it a gentle shake, turn the telescope upside down and try to pull it off using minimal force. This is particularly important on windy days.
- Repeat the test about once an hour. Check the fit every time you adjust the telescope or make any changes to it (such as changing the eyepiece)
- If you have any doubts about whether it is secure, secure the solar filters to the telescope with some adhesive tape or similar aids.
The rim of the 114 mm filter can be inserted into the tube or dew shield. Alternatively, it can be attached to the outside (as shown in the picture). A self-adhesive foam rubber strip is included to compensate for a few millimetres.
- When inserted, the filter fits inner diametersof 128–134 mm;
- when clipped on, the Filter fits outer diametersof 118–124 mm.
