Swan Extra Slim Filter Tips - Full Box Of 20 Total 2400 Tips

Product Information

This is our own proprietary "emergency solution" for uniting a world were manufacturers all over the world copy from each other - to the point that there are almost a dozen different pitches in use for male and female threads. Traditionally US-companies used to do a UNF-based pitch and the rest of the world went for metric threads - but these do vary from 0.5 to 0.75. For our CMOS-optimized filters we have created the following images showing which side of the filter should face the telescope.

Baader filter boxes can be attached laterally and above the other to create a sturdy unit. Each filter is then neatly in it's own drawer and characterised from the front with name, number and size of filter.Quite often we receive requests for a single filter in an off-standard size. In all cases we are sorry that we must answer as follows:

If you cancel you must return the goods to us at your own expense. You are responsible for the risk of loss or damage when you return the goods, so you should take out adequate postal insurance to cover their value. Lumicon hat 25 nm Halbwertsbreite und erfasst die [OIII]-Linie mit, ist also auch als [OIII]-Filter zu benutzen. Der Baader-Filter ist nur 15 nm breit und blendet diese Linie aus. Dieser Fakt allein wird wohl an einem Kometen nichts machen, wenn er nicht gerade vorm Zirrusnebel steht :) Eine geringere Halbwertsbreite heißt aber höherer Kontrast. Both thread sizes come with our proprietary pitch - which is not the same for the female and male threads.

The comparison between the luminance and swan-band images clearly shows the true power of the 15nm Swan-Band filter over a full-spectrum luminance filter. The doubly ionized carbon from Comet C2022 E3 (ZTF) is clearly visible in the images taken with the Swan-Band filter. Due to environmental influences such as light pollution, these are completely absent in my luminance images. Der Himmelshintergrund war mit dem Baader-Filter deutlich dunkler, das Bild ansprechender. In etwa wie der Vergleich von UHC (ohne S) und [OIII] an Nebeln. Das war von den Bandbreiten her auch zu erwarten.

Every single cell mounted filter delivered to our customers is cut as a round or square disc in the according size (1¼", 31mm, 36mm, 2", 50,4mm, 50x50mm, 65x65mm), and then is polished plane to a quarter wavelength on both sides on a computer numerically controlled polisher. After that, the polished blanks are submitted to the costly coating procedures. This sequence is also used for all unmounted filters.

Ich habe beide Filter an C/2023 E1 (ATLAS) verglichen. Komet Atlas ist derzeit (Mitte August 2023) noch um 9m5 hell und damit von einem dunklen Standort aus etwas für zumindest größere Ferngläser. Der Komet ist recht groß, 6'. Der Kometenschweif emittiert möglicherweise andere Wellenlängen als der molekulare Kohlenstoff der Koma. Welche Auswirkungen dies hat, muss ich noch ergründen. ATLAS hat ja keinen wahrnehmbaren Schweif. The “polished“ sheet is coated as the whole, and afterwards the filters are cut out in the desired size. This production method for filters is drastically less expensive than the substantially more sophisticated manufacturing of a Baader filter. In addition, different sized filters can be cut on demand, reducing inventory costs.
