Baader UFC Tilter
The effects of image tilt can ruin an otherwise great astrophoto. Image tilt (or image plane tilt) happens in imaging when an area towards the edge of the field exhibits out-of-focus or imperfect star images and is caused by the image sensor not being pefectly perpendicular to the light path. Focuser skewness (or "droop"), flattener/corrector lenses, extension adaptors, camera angle adjusters as well as inherent camera sensor tilt in the camera body itself are all causes of image field tilt. Being able to correct for this image plane tilt is important and essential to get perfect focused sharp star images across the field of view.
For those that do astroimaging with our Universal Filter Changer (UFC) we are pleased to annnounce a...

"Finding the way" has a long tradition at Baader Planetarium. The slogan got created by our companies founder Claus Baader – in 1966, when "the Baader Planetarium-Orrery" was announced to the world. And within those many years we always tried to find ways for our technical solutions – and the domes – to stand the test of time. The Baader Planetarium Orrery btw. might have the longest product existence in modern industry – we still produce it here in house – unchanged since 1966 (if you like, check a tiny bit of the print material published at that time).
Today we have a similar situation –...

QHY offers a very comprehensive and flexible adapter system that allows our cameras to achieve focus with a variety of accessories, including camera lens adapters, off-axis guiders, filter wheels and numerous optical systems. The many potential combinations of these items produce an equally large variety of back-focus distances that must be considered to make it all work together. This variety and flexibility, however, also can be confusing particularly for new users.This is one of the reasons why we at Baader Planetarium keep receiving customer inquiries on the subject of "How do I adapt my QHY camera to my telescope?"
How do I adapt my QHY camera to my telescope?
If you use a refractor, a Schmidt-Cassegrain or a Newtonian telescope WITHOUT any other special optical...

The L-series lineup was born out of the dream to create the most versatile and cost-effective direct drive mount. Whether your goal is capturing beautiful astrophotographs that are out of this world, tracking fast moving satellites, or tracking objects that are not in orbit, the L-series will help you reach those goals all while being extremely simple to operate and maintain.
The results of the L-series tracking performance whether at sidereal, or other rates utilized by astrophotographers, speaks for itself in these sample images captured by our customers.

On 2 June 2021, our customer Alan Jadanić sent us these amazing solar images taken with the
TEC APO 140 f/7 Fluorite Apochromat (#1351005, € 8500,-)
. He used our kam unser D-ERF Energy rejection filter 135mm, a Solar Spectrum H-alpha Filter and the
Research Grade TZ-3 Telecentric System (3x focal length) (#2459257, € 395,-)
. Thank you!
We would like to empahasise the multifunctional usability of the TEC APO 140 FL for DeepSky, visual observations and H-alpha. This optic can really be used day and night and is therefore a real all-rounder.
Dear Mr. Baader,
I have spent a few days with the TEC 140FL and a Solar Spectrum RG38 0,5Å filter and I must say that it is a very good filter both...

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...

Smaller-Sized Filters with Baader UFC-System :
It may only be an adaptor but this little piece of anodised metal will let you use a range of popular astroimaging cameras with Baader Universal Filter Changer (UFC) on Celestron's RASA 8 telescope thus allowing you to swap filters quickly and easily.
Unlike the Baader UFC telescope adaptors for the 11″ RASA and RASA 36 that are mated to the corrector lens group cell face-plate and secured with the knurled retaining ring, this adaptor screws onto the male outer threads of the lens group housing itself. So you would remove the RASA 8’s retaining, the T-2 or C camera adaptor and then the clear filter, and then attach the UFC Base with its RASA 8 UFC adaptor in...

Smaller-Sized Filters with Baader UFC-System :
We've been asked a few times recently on how to set up the Baader UFC for use with a DSLR and a range of wide-field imaging refracting telescopes. So we thought we would write a short blog on some ways this can be done.
Let us start from the telescope side first.
All the enquiries we have had, the wide field refractors have 2" barrel focusers, so there is our starting point. The telescope side of the UFC Base (to which everything else in the UFC system is connected to) uses Baader's S70 dovetail adaptors to allow the UFC to fit to telescopes.
Looking at the UFC main diagram above Baader do a
Baader UFC S70 / 2" SC-thread...

In just under a month, an annular Solar eclipse will take place on the morning of Thursday June 10th. An annular eclipse occurs when the Moon passes between the Earth and the Sun but the Moon's apparent diameter is smaller than that of the Sun's due to the Moon's orbit being elliptical and it being further away from our Earth (at/near apogee) at that time. This leads to the outer parts of the Solar disc being "exposed" in an annulus or ring - often called "ring of fire".
For those lucky enough to live in north-east Canada, western Greenland and far eastern Russia, will get to see the annular phase event which will last for a maximum of 3m 51s over north west Greenland. For...

Cooled CMOS imaging cameras for astronomical use have come a long way over the last few years and they are here to stay. The
QHY268M PH, BSI Cooled Medium Size APS-C Camera (Photo) (#1931096, € 2698,-)
camera has been hotly anticipated and has become a focus for a lot of astrophotographers for its high specifications, build and image quality.
The QHY268M is a monochrome cooled CMOS camera that utilises a very sensitive APS-C sized Sony IMX571 sensor. Typical of other QHYCCD camera bodies, the 268M features a matt black cylindrical design with, in this case, a red colored band around the body at the sensor end with QHYCCD’s name and logo and the camera model – QHY268 – clearly labelled. The body is 90mm in...
