Viikonloppuna vietetään valtakunnallista tähtiharrastuspäivää paikalliset yhdistykset järjestävät tuolloin tapahtumia eri puolilla Suomea!
Myös Porin Karhunvartijat ovat viettämässä valtakunnallista tähtiharrastuspäivää, sekä Suomen luonnonpäivää Porin Yyterissä kylpylähotellin rannalla! Yleisö pääsee tuolloin tutustumaan kalustoomme, sekä yhdistyksemme toimintaan ja sään salliessa havainnoimaan Aurinkoa, yhdistyksen Aurinkoputkella!
Olemme paikalla klo 12-16. Osoite: Sipintie 1, Pori.

Hello everyone! I recently bought a new telescope, Ts Optics Ed Apo 80/560 refractor. I was very excited to take firstlight with it, but I had to wait because nights were so bright in the summer!
But now… It’s the darkest time of the year! So here is the firstlight with my new scope, hope you enjoy it. Object is ofcourse Andromeda Galaxy with it ”friends” (M32 and M110). The total exposure time is 1 hour and 26 seconds, ISO 800 (modded Canon Eos 1000d), processed with Pixinsight.
This was my first attemp to observe Aalto-1 satellite. I managed to get it on the spectrum waterfall (Video on youtube)! I had Basic TV-Antenna (VHF/UHF), RTL-SDR dongle (Nooelec Nesdr, price about 20$) on a laptop (Dell Latitude). I had also LNA (LowNoiseAmplifier), but next time I will remove it from my setup.
Here is More detail about Aalto-1: Aalto-1
Okay I have somekind of obsession when it comes to this object, this is close to 100th version already… It is my favorite Nebula and in my opinion, It is most hardest object to do post processing. So, of course I think it is great to see how much better you have come in image processing. What do you like?
Summer is here in Finland… That means we really dont’t have a decent night sky (It’s almost like in the daytime), but now the days are going to be shorter and night sky is coming slowly back to us.
But what Finnish amateur astronomers are doing in the summer? Taking a long nap? Answer is no! We have a lot different pheonomenon and other great things to observe, like Halos, rare clouds, rainbows, whirlwinds, hailstorms, lightnings, etc.
Now you may been thinking, that can we see any Aurora Borealis at the summer? Well, no we don’t… At least I haven’t seen them at summer, but closer to winter we start to see them as well again!
Then there is also a one thing worth of mentioning… In this year Finland got first satellite to space: Aalto-1. Many Finnish amateur astronomer loves also, amateur radio hobby, and they are listening Aalto-1 morse codes as we speak (check Naavis page)!!! I have been doing radio observing myself (meteor echoes 50Mhz frequency) and I’m going to do some experiments nearby future with the hydrogen line observations in 1420Mhz frequency, with my rtl-sdr dongle.
Here is some pictures what yo can observe in Finland at the summer:
I wanted to try how my new I Phone 7 can manage in astrophotography. So I first tried to take some single exposures and they were pretty decent! Then i checked the formats of the videos and it came clear to me, that Autostakkert supports the format… So I took few seconds of video and stacked them together as a single image. This is the result of 1500 frames! Next time, I will try to take video of Jupiter.
