  • Important System Driver Update Information - For All QHYCCD Cameras

    Breaking news from QHYCCD: QHY - Important firmware driver upgrade 9/21 Based on an update notification of the USB chip, we added a new API in the firmware of all QHYCCD cameras between 2021.7.10 and 2021.9.4. According to the description, we were expecting that this modification would increase the stability of the USB link. Unfortunately, however, we have received feedback from our users that it can cause a random crash in single frame capture mode on some computers. These random events can occur after some minutes or some hours or even longer time frames. To test these reports, we changed back to the system driver release before 2021.7 and have confirmed that without this new API the random crashes disappear. In order to avoid this...
  • NEW: Baader SunDancer II H-Alpha Filter – Test Review

    I was lucky enough to be able to "play" with one of the first SunDancer II H-alpha filters and see what it is capable of. Even though I am not one of the most experienced H-alpha observers, I have been able to observe the sun with the two H-alpha telescopes of the Observatory in Heilbronn/Neckar again and again for more than 20 years. These are a 20/20 H-alpha filter by Wolfgang Lille with 0.8Å on the 150/2250 refractor (which complements a classical prominence filter), and a Lunt LS-60 telescope. I freely admit that I find the concept of the Lunt convincing, especially for public observatories: a complete telescope with which nothing can go wrong. It's foolproof, which is especially important in an club where many...
  • The Baader UFC Tilter Adapter (Part 10)

    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...
  • QHY Adaptersets

    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...
  • PlaneWave's L-series out of this World Tracking Performance

    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. (1) M101 with CDK600 by Kurious George, (2) PK 136+05 with CDK500 by Jeff Lovelace, (3) NGC 4565 with CDK600 by Kurious George, (4) NGC 225 with CDK350 by Kevin Morefield, (5) Komet NEOWISE with CDK600 by...
  • Solar imaging with the TEC 140 f/7 Fluorite Apochromat

    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...
  • Baader's RASA 8" UFC telescope-side adaptor (Part 9)

    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...
  • Using Smaller-Sized Filters with Baader’s Universal Filter Changer (UFC) (Part 8)

    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...
  • QHYCCD 268M Monochrome CMOS Astronomical Imaging Camera: Overview and a first light from Bortle 7 skies

    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...
  • First Class H-alpha Solar Filters by SolarSpectrum

    Temperature controlled H-alpha-filters (lambda = 656,3 nm) with electronic temperature control (combined heating and cooling!) All SolarSpectrum H-alpha filters at a glance --> Such professional filters show an unsurpassed abundance of details by using the full aperture of the telescope and are thus the first choice for semi-professional observers / photographers as well as for scientific use. Solar Spectrum H-Alpha Filters give you an incomparable view of our Sun's eruptive surface. The SolarSpectrum filters follow the classical design and are placed behind the telescope in the focuser (although this requires a D-ERF energy rejection filter in front of the lens). In combination with a telecentric system tuned to the focal length of the telescopic, between 2/3s of the aperture and the full aperture of the...
