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

Product Information

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'. Each filter coated individually, with sealed coating edge (NOT cut out of a larger plate with coatings left exposed, read more) In the old days, colour filters for visual planetary observations were not screwed in the front part of the eyepiece, but were simply placed between the eyepiece and the eye. Plane-parallelism of these filter glasses was not important, because they were not in the optical path of the telescope. Swan-Band-Filter wurden bislang nur von Lumicon produziert. Baader hat einen Filter herausgebracht, der sich von den Lumicon-Filtern unterscheidet. For our CMOS-optimized filters we have created the following images showing which side of the filter should face the telescope.

Both thread sizes come with our proprietary pitch - which is not the same for the female and male threads. Since the C2 filter allows only the green carbon transmission to pass through, the dust tail illuminated by the sun could be highlighted very clearly with the new 20 nm H-alpha filter. Also a only mag 16.2 faint C/2022 U2 (ATLAS), which is overtaken by the mag 5.8 bright C/2022 E3 (ZTF), could be photographed: Our 1.25" filters have a M28.5 male (and M28.5 front female) thread / our 2" filters have a M48 male (and M48 front female) thread

The images were taken on January 29, 2023 directly from the outskirts of Mannheim, Germany. The test series consisted of exposures with a normal LPS luminance filter (Hutech IDAS LPS-P2) and single exposures with the Swan band filter. Based on these considerations, soon after the release of their new CMOS filter range, I asked Baader Planetarium if they would lend me a CMOS blue filter Baader RGB B-Filter – CMOS-optimized The variety of uses for filters in amateur astronomy has considerably increased during the last decade, enabled by both more accurately manufactured optical accessories, and, above all, by the “digital revolution“. 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. Just in time for the introduction of the new C2 Swan-Band filter, a bright comet, comet C/2022 E3 (ZTF), offered itself as a test object. Our customer Andreas Bringmann was one of our first testers - see more under TAB Review

It would be highly interesting to make a comparison exposing a comet through both an OIII filter and the new C2 filter. Thus, with the larger carbon gas cloud, one could deliberately highlight the inner nucleus of the comet. screw-in thread for 2" eyepieces on telescopes as well as for lens-side mounting on binoculars up to 45mm aperture, and finallyShould you really have some reflections with both positions it can be more effective to add a spacer between filter and camera, eventually shifting the reflection out of the image field. With focal correctors having curved surfaces changing the filter-lens distance could help also. The Baader C2 SWAN-Band-Filter with ≤ 15 nm Half-Band-Width isolates the two C2 lines at 511 and 514nm – leading to a contrast gain for comet hunters!

Everyone has different requirements and goals and with a myriad of filters available today; how do you choose the right filters to unleash the full potential of Astrophotography? Just in time for the introduction of this new C2 Swan-Band filter, a bright comet, comet C/2022 E3 (ZTF), offered itself as a test object and one of Baader Planetatrium’s customers (Mr Andreas Bringmann) was one of the first testers. The image of that comet is below and was taken from a city with an almost full moon. The image easily shows the amount of “doubly ionized carbon” (the carbon excited to glow radiates only in the wavelengths 511 nm and 514 nm ) emitted by the comet. The filter shows the complete extension of the ion cloud around a comet:
