Walter's son used a collection of night sky time lapse videos taken in 2014 and 2015 high up in the Alps of Salzburg and Carinthia to create a nice movie underlaid with music.

Nightsky Collection 2014-2015

Howdii and Andi observed and imaged Supernova 2017ein in NGC 3938, during June 11 - 15, 2017. Howdii has seen this Supernova in a 4" Triplet APO, a 10" Dobsonian and a C8, Andi has seen it in the C8. For imaging they also used the C8 with an Astro Physics 0,67x Reducer. Read Howdii's Report in German).

Supernova 2017ein

After a long pause, Walter finally created a new astrophoto: The Iris Nebula in Cepheus, images taken with a 9.5" Newtonian and QHY8 CCD camera in September 2016 at the Wallackhaus, Carinthia. Photographic conditions were not perfect, thin Cirrus clouds partially obscured the field-of-view.

NGC7023

The TS Individual 102/1100 achromatic refractor is one of Howdii's favourite telescopes. He argued this model is as good as the legendary Zeiss AS 100/1000. On June 2, 2017, Howdii had the occasion to do a comparison of these two optics on an elusive target - Jupiter. Seeing was really good at this site. The views of Jupiter were great! And, the 102/1100 is really on par with the Zeiss AS 100/1000! The 102/1100 also did a respectable job compared to a Celestron 102/900 Fluorite lens. Read Howdii's Report (in German).

After some time of use and abuse by the owners Howdii got the 25" f/4.5 Dob back for servicing. In consecutive tests together with Andi he found some minor flaws to be fixed. Observing with this big aperture was no fun during some test sessions in early spring because of wind and bad seeing. However, on May 28, 2017 all went well - oh, wait a bit. Some glitches at the beginning. But for the rest of this test and observing session Howdii, together with Roland and Andi had a quite good sky and a lot of fun in the fields near Niederleis. They observed many late-spring objects. Read Howdii's Observation Report about this night (in German).

25 Zoll Dob

Howdii wrote an article (in German) about new city lights following the EU EED. He documented some of the old city lights of his hometown and also some new ones. His conclusion: We now have full-cutoff lights we desired so badly. However, they are too bright, especially LED lights. So, nothing is won.

full-cutoff light

Howdii and Andi imaged the recently discovered Supernova 2017eaw in NGC 6946, on May 18, 2017. They had to fight gusty wind and bad seeing, but somehow managed to get some useable images. Read Howdii's Report in German).

Supernova 2017eaw

iOptron ieq45 Pro - Howdii got this mount for a customer and tested its performance. He subsequently wrote a Test Report (in German, April 2017) about this model and referred also to the evolution steps of the ieq45. Howdii found fine guiding performance on this sample, which he carefully documented. This model of the ieq45 Pro provides refined gearing and stepper motors, whereas formerly servo motors were used. This new model has a real time clock, so it's no longer needed to wait for the GPS satellite fix. A new and quite unique feature allows the mount to recover from power failure during the session. So one simply is able to continue the session without loosing position of the scope or star alignment. A rigid hard-wood tripod is highly recommended for this mount.

iOptron ieq45 Pro

Howdii and Andi observed and imaged comet 41P/Tuttle-Giacobini-Kresák during the last days of March, 2017. Read Howdii's Notes about this comet in German).

comet 41P/Tuttle-Giacobini-Kresák

Howdii observed Mercury at dusk during the last days of March and first days of April, near Mistelbach. Read Howdii's Observation Report, in German.

Mercury

Howdii delivered the EQ6-R mount to his customer and surprisingly, at this site was a pretty clear night. What else to do than put the mount on its stand and attach a telescope to it? Howdii wrote a short report (in German, Feb 27, 2017) about those observations. The telescope was well-known for him, it was his ex-presentation model of the Bresser 152/1200 achromatic refractor.

Skywatcher NEQ6-R SynScan - Howdii got this mount for a customer and tested its performance. He subsequently wrote a Test Report (in German, Feb./March 2017) about this revised model. Howdii found fine guiding performance on this sample but also a surprising detail, which he carefully documented, and generally attributes the NEQ6-R good characteristics and handling. This revised model is better in many respects than its venerable predecessor, the NEQ6. Like the NEQ6 the NEQ6-R is best mounted on a rigid hard-wood tripod.

Skywatcher NEQ6-R

Howdii tried to observe Pease 1 (a Planetary Nebula within the Globular Cluster M15) with his 5.7" f/6 Maksutov-Newtonian and, succeeded. It wasn't that hard as expected. So Howdii tried to do this with the 102/1100 Achromatic Refractor. What about it? It's more the problem to find the location of Pease 1 than to see this object with this 4" lens - well, for a very experienced observer. Read Howdii's Observation Report, in German.

Niederleis Beobachtung

After some observations with the Vixen VMC 260L Howdii returned this telescope to the owner. There they had a quite good sky and observed some deep sky objects near Ratten, Styria. Read Howdii's Observation Report, in German.

VMC 260L

Howdii observed some deep sky objects during a moonlit night at the observatory site of the Leiserberge Sternwarte club near Klement/Au on August 13th, 2016. Read Howdii's Observation Report, in German.

Howdii and Andi observed the Perseids and caught some meteors photographycally on August 11th, 2016, near Mistelbach. Howdii again observed some Perseids near Klement/Au on August 13th, 2016. Read Howdii's Observation Report, in German.

Perseide

After some visual observations with the Vixen VMC 260L Howdii was eager to do some astrophotography with it. But what mount for it, because of the long focal length of this scope. Fortunately, Howdii got also a Celestron CGE mount for testing, so there he went. Howdii and Andi used a quite dark sky at Mistelbach, however, seeing was only mediocre. Despite this, they managed to get the mount in guiding to image M57 and M27. Howdii has written a Test Report (in German, August 2016).

VMC 260L Fototest

Howdii got an APM 140/980 Doublet SD-APO for a customer and testet it visually as well as photographically (July/August 2016). This scope features a retractable dew shield, a handle on top of the tube rings, a Losmandy style dovetail rail, a 2.5" RPA focuser and a mounting base for finder scopes. The optics shows pinpoint stars across the field and a nearly textbook-like star image at high power. There is a trace of pinching, and a bit of spherical aberration. The color correction is good for a lens of this size and type. Visually, bright stars show up in their true color, however, traces of red to blue are shimmering in the diffraction rings. Photographycally, bright stars do show some false color. There isn't enough clearance between dovetail rail and dew shield, so these two parts accidentally can get in contact what causes scratches on the back ring of the dew shield. This is annoying. The vendor has promised to solve this problem. Howdii wrote a Test Report, in German.

APM 140 f/7 SD-APO

Howdii reobserved some of the objects of his last observing sessions and some other objects with an APM 140mm f/7 SD-Doublet Refractor on July 29th, 2016. He had a quite dark sky at the Oberleiser Berg. Read Howdii's Observation Report, in German.

SD APO

Celestron Ultima 8. This 8" f/10 SC was produced from 1989 onward. It features a heavy-duty fork, and this sample was supplied with the heavy-duty wedge, however, PEC is not available on it. The Ultima 8 was well known for its stability and for its good optics, as well as for the accuracy of its RA drive. Howdii got this scope for inspection. Some parts were missing, and the RA drive did not work. He was lucky to supply the missing parts and could fix the drive electrics. The optics proved very good, and, as a surprise the collimation of the optics was spot on. The stability of the scope is ok, it shakes when bumped, but the vibration damping is good, about one second. Howdii wrote a Test Report, in German, July 2016.

C8 Ultima

For the fun of it Howdii reobserved some of the objects of his last observing session with a 102mm f/7 Triplet APO Refractor on July 10th, 2016. He chose the hill on the east of Mistelbach as observing site. The sky was quite good, however, not as good as last time at the Oberleiser Berg. Read Howdii's Observation Report, in German.

APO

Howdii and Andi had a pretty good sky at the Oberleiser Berg on July 6th, 2016. Howdii used a Vixen VMC 260L Field-Maksutov telescope for visual deep sky observing, Andi did this with his Celestron 8" SCT. Howdii spotted some quite tough globular clusters and observed some planetary nebulae, as well as some typical summer sky highlights. Read Howdii's Observation Report about this night, in German.

Teleskope

Howdii has tested a Celestron C9.25 SC. The C9.25 is well know for good optics and lesser field curvature. This comes along with an increased tube length and a larger central obstruction, where the Fastar secondary locking ring adds some millimeters. However, this sample proved a smooth backlash-free and shifting-free focuser as well as excellent optics. Simply said, it's the best SC telescpoe Howdii has ever seen. Howdii has written a Test Report (in German) about it.

C9.25

Howdii has tested a second-hand (in near mint condition) Lacerta 72/432 ED Refractor both visually and photographically (togehter with a 0.85x Reducer). This little Lacerta ED scope features a nice Octo 2" focuser. Visually, the performance is fine. There is only a bit false color and a trace of spherical undercorrection, nothing else. This lens is sharp. Photographically, it is capable of delivering nice wide field images. Howdii has written a Test Report (in German) about this telescope.

Lacerta 72 ED

Howdii has tested a vintage second-hand Scopos 90/600 ED Triplet APO both visually and photographically (June 2016). Visually, the optics proved ok. The color correction is really good. There is some spherical undercorrection and a trace of pinching. However, nothing else. This lens will take some time to cool down. The Crayford-style focuser is a bit tricky, but can be tamed if carefully adjusted. Photographically, this triplet-lens is capable of delivering quite nice images. Howdii has written a Test Report (in German) about this telescope.

Scopos ED APO

Howdii and Andi imaged Supernova 2016cok in M66 and Supernova 2016coj in NGC4125 via DSLR and CCD. They also tried to observe those Supernovae. SN 2016coj was quite easy to spot, but Howdii also succeeded to catch the faint Supernova 2016cok. They imaged also Mars via Webcam. They used three nights, on May 31, June 6 and 7, 2016, at and near Mistelbach. Read Howdii's Observation Report in German.

Supernova 2016coj

Howdii and Andi observed the transit of Mercury, the passage of this planet across the surface of the sun on May 9, 2016 near Ladendorf. They used Howdii's 100/800 Triplet APO for visual observing and afocal projection photography as well as Andi's 102/1000 achromatic Refractor for focal photography. Read Howdii's Observation Report in German.

Merkurtransit 2016

Howdii and Andi attended the Weinviertel Teleskoptreffen near Klement/Au on May 6th and 7th, 2016. For those two nights they brought along four telescopes: Howdii's 5.7" f/6 Maksutov-Newtonian, a 102/1100 Refractor, a Vixen VMC 260L Field Maksutov and a 102/714 ED Refractor. They observed Jupiter, some Galaxies and some typical highlights for such an event. Read Howdii's Observation Report in German.

Teleskop Treffen Weinviertel 2016

Howdii got an Intes-Micro Alter M603 for repair. Solving the focusing issue was no problem. Howdii inspected the scope thoroughly and found some hairy looking dirt on the meniscus lens - probably fungus. So he had to clean the lens carefully and then to re-collimate the optics. Howdii also star-tested this scope. The visual performance is affected from cooldown problems, and the optics showed some spherical undercorrection. Good seeing and thermal equilibrium assumed, this scope can for sure deliver quite nice planetary images. However, this will not easily come together. Howdii has written a Report (in German, April 2016) about this telescope.

Intes-Micro Alter M603

Howdii has tested a Skywatcher 100/900 FPL-53 ED Refractor both visually and photographically (March 2016). Visually, the optics proved quite nice. The color correction is ok for this ED Refractor, but compared with an FL-102 lens - the Fluorite can't be beat. There is a bit of spherical undercorrection and, maybe a bit of pinching. Photographically, this ED Refractor delivers fine star images. Howdii has written a Test Report (in German) about this telescope.

Skywatcher 100 ED

The Central Cygnus Region around the stars Deneb and Sadr is a prominent Milky Way area full of stars, light and dark nebulae, and many other objects. Photo taken with a modified Canon 350D and a zoom lens sent to 70mm during my Astro-Expedition to the Großglockner-Hochalpenstraße in September 2015.
