Skywatcher’s Synguider

Having limited time to spend while trying to set up all the equipment, level the mount parallel to the ground, adjust the balance of your mount with the telescopes attached on it, polar align your telescope, if you have a GOTO mount then you may need to star align, … The list can be made long and supposedly you do road astronomy then your time is consumed by many tasks this late evening planning on loading your car and transferring your equipment to a remote location free from light polution.

You’ve been waiting more likely for the perfect weather circumstances by now and have been thinking all the time about taking shots of your favorite object? Then welcome to the club. By the time you are ready to start your exposures a cloud is passing by, blocking the view. Other times a mist is joining the scene, or technical issues arise. Either way you’ve been wasting way too long time on things that could instead been made easier.

Skywatcher came up to a solution when it coms to guiding and created a gadget by considering that guiding is no easy business for anyone, considering your weight distribution while you’re tracking the heavens above having backlashes, attaching a camera adding by more weight to your equation, your power supply may not be even, or many other factors that may add to your guiding frustration.

With current solutions on autoguiding you need a special camera, software and a laptop. But why make things so complicated when there is the perfect solution for users with Skywatcher’s GOTO-mounts?

I strongly recomment this synguider, and I’ll start posting photos showing the difference between life before synguider and after 😉

Partial solar eclipse in Sweden

Posted on Updated on

Unfortunately we didn’t get the chance to see anything behind the thick layer of clouds and heavy mist passing by the entire morning yesterday. However, we had news channels, local radio stations and news papers droping by asking us about facts regarding this fenomena. Seems when it comes to Sweden that only Stockholm had good visibility.

I’m going to attach a few Youtube clips I saved as a memory from this event.

The interviews were made by Swedish national TV (short: SVT, Sveriges Television)

The Sun through H-alpha

Posted on Updated on

Less then 48 hours left before the partial solar eclipse that occurs during the tuesday morning 2011-01-04. I was testing my equipment and saw that there were a few sunspots. The image is photographed with a Canon EOS 50D at ISO 800 through a Lunt LS60THa H-alpha telescope.

The news have already been requesting curiously on details about the partial solar eclipse on tuesday. Regardless the weather conditions we will be there taking care of our guests and giving interviews. If the weather allow us to observe anything I promise to get back here with some photos.

More newspapers publishing about the solar eclipse on tuesday:

Using new stuff

Baader UHC-S

Studying physics is really limiting my time from doing fun stuff, especially when it comes to one of my most favorite hobbies (astrophotography & star gazing). Even though of my time limitations, I couldn’t stop myself from finally buying new equipment I’ve long desired and saved money for, such as a mount upgrade (EQ 6 Pro), a new camera (Canon 50D) and two refractor telscopes from William Optics (Equipment page). I’m definetely now a happy amateur astronomer and even if I’m not able to perform any backyard astronomy these days, the weather wouldn’t allow me anyway and there fore there are no hard feelings since I miss nothing.

Although that is not the truth entirely, I’ve been out late evenings scanning the night skies, focusing on my primary goal objects such as M31 (Andromeda galaxy), M13, Double cluster and the Pleiades. These objects will definetely occupy my time for hours (apart from photo processing the images). I’ve also upgraded myself to Baader’s UHC-S filter which is a fine filter suited for astrophotographers living in suburban areas.

During mid october this year we had comet 103P/Hartley 2 passing by between Cassiopeia and Perseus constellation but I must admit that this comet was absolutely nothing spectacular and definetely not worthy the time. I went out trying to locate this object which was around magnitude 8 and even though with well trained eyes it still looked like any other star. No tail or obvious halos around it even by using wild imagination, so I decided instead to spend some time gazing at galaxies.

Perseids meteor showers

Posted on Updated on

Every year in August between the 10th and 13th, we get the opportunity under good weather circumstances to observe the anual meteor showers caused by the Perseids. These small particles mainly made of dust are falling through the earth’s atmosphere from a radiant point in the sky located close by the Perseus and Cassiopeia constellations. These meteor showers are nonetheless remains of an old comet which passes close by our planet over a period of 130-135 years and was last seen in 1992 by the Japaneese astronomer Tsurukiko Kiuchi. The comet is named Swift-Tuttle after the two astronomers who independently were the first observers in modern history during the comet apperance in August 1862 (Lewis Swift and Horace Parnell Tuttle). Spectral analysis points out that this comet shares similarities with Halley’s comet which is rich in ammonia, water and carbon dioxide and also clasified as NEO (Near Earth Object) as it is approaches earth in a distance of 4 miljion kilometers. The chances of an impact with our planet is 1 in a 1,000,000 which is much less then the frightening asteroid called Apophis were chances are much larger; 1 in 15,000.

This year our observatory will be opento public between 11th to 13th of August 21:30 to midnight allowing all interested to come and visit us under guidance from the observatory staff.

Summer projects and the 472 Roma ockultation

Posted on Updated on

During June-July at Tycho Brahe observatory we were preparing for a large project that would involve the cooperation between many amateur astronomers from different locations in Sweden. The Swedish assosiation for amateur astronomers (SAAF: Svenska Amatörastronomiska Föreningen) helped us to get in touch with other amateur astronomers across the country. Together with my collegue Arne L Ohlsson we started to put hard work on planning, coordinating meetings, assembling nessesary instrumentation and dealing with time pressure.

The ockultation is all about a large rock out in space, or more commonly called an asteroid named 472 Roma passing infront of the delta star (Yed Prior) in the constellation of Ophiucus, causing this large red giant star to dissappear for a around 5 seconds. This asteroidal passage was meant to be easily observed from our location, but negative observations outside the occultation shadow would provide a lot of information regarding the star itself.

It has been mistaken for a long time that the delta star in Ophiucus would be a double and for the first time an asteroid would occult this star and reveal it’s secrets for us. Unfortunately just before the occultation occurred, heavy clouds surounded our area. That was our worse case scenario that just took place, leaving us with unanswered questions.

In the morning we heard that the German and Belgian astronomers were more lucky then us and that many positive reports started to fall in!
