APF-R : Absolute Point of Focus
APF-R goes online as official plugin in Adobe Photoshop Christoph Kaltseis is a Photoshop expert and an experienced astrophotographer. In recent years, he has developed APF-R (Absolute Point of Focus), an innovative image sharpening process in Photoshop that has attracted considerable interest among experts. The Hubble Space Telescope team has been using his method for over 2 years. Adobe Photoshop has now introduced the easy-to-use APF-R Photoshop CC plugin for Christoph's complex process. The tool sharpens images using APF-R with just a few clicks, even without much prior knowledge. The plugin has already proven many times that it can meet even the high quality standards in astrophotography. Read a very interesting in-depth interview with Christoph Kaltseis on Picture Instruments about his experiences in astrophotography. Christoph reveals the tricks he uses to get the finest details out of his stunning images: "The secret behind Christoph Kaltseis astro images" on Picture Instruments - News (picture-instruments.com) It's not everyday that one could find a new sharpening technique or algorithm that would increase the sharpness of delicate threads of a nebula or dust lanes at the bright centre of a galaxy without significantly increasing noises or over-saturating stars in astronomical images. So when APF-R...

DART impact - NASA used large 100mm Baader Bessel filters
“The filters worked exceptionally well and we got terrific images post-impact. (See attached photo in Bessel R) We couldn’t have done it without your help, and we are very grateful! Such an exciting and successful mission to be a part of (and lots of observing work).” NASA Hazardous Asteroids research used large 100mm Baader Bessel filters to successfully image DART impact with the MRO 2.4-meter telescope On the 11th of October 2022 after two weeks of analysis, NASA confirmed that the DART mission impact changed the Asteroid's motion in space. NASA's Double Asteroid Redirection Test, or DART for short, used the kinetic impact of a spacecraft to successfully alter an asteroids orbit. The mission involved crashing a spacecraft at 14,000 miles per hour into an asteroid , named Dimorphos which was orbiting a larger asteroid Didymos, and measuring the change in orbit to understand the deviation achieved. This is the first time a celestial object motion has been altered on purpose and the first full-scale demonstration, proving asteroid deflection technology to be a success. In order to view the impact, and to obtain light curve measurements to measure the asteroid deflection achieved, the DART mission team used the Magdalena...

Baader Photometric Filters: Dark nebulae appear in a new light
Combination of photometric and RGB filters to highlight dark nebulae Photographing dark nebulae is a fascinating challenge for astrophotographers, often posing difficulties due to the low brightness and high contrast between celestial objects and dark nebulae. This often requires the use of different techniques and exceptionally dark skies to bring out fine details in the dark nebular structures. In this test report, we examine the photographic results and the effectiveness of the combination Baader SLOAN/SDSS (ugriz') Filter Set – photometric Baader SLOAN/SDSS (ugriz') Filter Set – photometric (various versions available) und Baader RGB Filter Set – CMOS-optimized (various versions available) to evaluate its effectiveness in improving contrast and detail, as well as enhancing them in all their colorful glory, while maintaining natural color reproduction. Equipment used: All single frames and the final image were taken with a QHY 268M PH, BSI Cooled Medium Size APS-C Camera QHY 268M PH, BSI Cooled Medium Size APS-C Camera (#1931096, € 2820,-) and the Celestron RASA 11“ as well as a selection of 9 different filters, which were changed manually using the UFC (Univeral Filter Changer) System. The following filters were used: Baader RGB Filter Set, Baader SLOAN g‘-, r‘-, i‘-Filter, Baader UHC-L Booster,...

Amateur Astronomers take a look through the Cloud Cover of Venus with our SLOAN Filters
Amateur astronomers successfully explore Venus with Baader SLOAN Filter Even today, amateur astronomers can still contribute to scientific research. For example, our new photometric filters now open another window into the depths of the atmosphere of the planet Venus. Venus amazes researchers. It is as big as the Earth, but extremely different from it. Venus is a hellish world with temperatures of up to 450 degrees at the surface. The reason for this is an enormously dense atmosphere, which generates a pressure that only exists at an ocean depth of 900m on Earth. This atmosphere consists of 90% carbon dioxide, a dense layer of sulphur dioxide clouds makes it opaque to us. There are only a few narrowly limited wavelengths in which a space probe camera or even a terrestrial telescope can hint at what lies beneath the cloud cover, which for the visual observer is simply brilliant white and contourless. It has been known for some time that various structures in the clouds are visible in ultraviolet light. The US space probe Mariner 10 delivered the first images during a flyby in 1974. They show the clouds at an altitude of about 60km. It was not possible to...

First Light with Baader SDSS filters by S. Ziegenbalg
IntroIris NebulaPleiadesLDN 1495 Attn. click above images for complex content Both, CMOS and CCD cameras designed for (amateur) astronomy typically have a spectral sensitivity from 400nm to more or less 850nm. But RGB filter sets for astronomy only use the range from about 400nm to 700nm and the on-sensor color filter arrays of consumer cameras only cover about 420nm to 640nm. That means, about one third of the spectral bandwidth is wasted. The three central filters used for the Sloan Digital Sky Survey (SDSS) split the the spectral range of interest into three approximately equal parts: G': 410nm to 550nm, R': 555nm to 695nm and I': 695nm to 845nm. So these filters would be a perfect choice for three-color images with modern cameras. That's probably one reason why these filters became quite popular in professional astronomy. But professionals normally use custom-made filters which are out of reach for amateurs. Baader Planetarium is now the first company which offers these SDSS filter to a wider clientele. This article presents tests and first lights of the long awaited SDSS G', R' and I' filters and compares them with RGB shots. All SDSS filter images in this article are taken with QHY600L cameras...
