The intial discovery was made by Mikko Päivinen (Rajamäki, Finland) on 26.12.2008 and I confirmed the discovery next evening by taking several unfiltered exposures of the target. After some checking and rechecking Arto Oksanen from Jyväskylän Sirius reported ... http://www.kehusmaa-astro.com/2008/12/28/new-supernova-found-in-pgc-14286 A broken display adapter was a reason for my troubles with the computer. After changing the adapter, everything (or almost) started to work. I continued having troubles with Cloud Sensor Graphics software though but after removing and reinstalling it (to another directory), solved my problems. I seriously need to consider a ... http://www.kehusmaa-astro.com/2008/12/19/observatory-computer-back-online-2 Another setback for SRO. After installing latest XP updates and reboot, my computer screen went totally black. No BIOS or boot information, nothing. It kept running though and were even able to update the weather graphics. My diagnose is that the video card is broken. The only problem is that ... http://www.kehusmaa-astro.com/2008/12/14/observatory-computer-down Last night I continued testing automated session with CCDAutopilot. Target was asteroid 133 Cyrene. This is data for more than 4 hours. Individual exposure 2 minutes and 103 data points. 544 http://www.kehusmaa-astro.com/2008/11/07/133-cyrene I decided to have this asteroid for my target when testing CCDAutopilot. This session was fully automated for almost 4 hours (I was a sleep when session ended). Everything went well and here is the result. There is a sum image where asteroid movement is visible and lightcurve to see ... http://www.kehusmaa-astro.com/2008/11/06/376-geometria 534 With only six days in between observations, this dwarf nova faded away for my equipment. On 22nd of September I was able to catch it with my 8" SCT but six days later it was gone. Light curve below. 532 http://www.kehusmaa-astro.com/2008/09/30/v466-and-faded-away 536 This supernova was found by Koichi Itagaki from Japan. It's very bright and clearly visible in my 7 minutes exposure. Taken with 8" SCT and STL11K. http://www.kehusmaa-astro.com/2008/09/30/bright-supernova-in-ngc3147 Asensin jalustaan eilen tulleen uuden kaapelin ja testasin moottoreiden kunnon. Kaikki toimii, joten seuraavia selkeitä odotellaan. Silloin voin synkata jalustan uudelleen ja pääsen tositoimiin kuvaustouhuissa. http://www.kehusmaa-astro.com/2008/09/18/astro-physicsin-jalusta-kunnossa After a long process I finally got package from AP. It included their new adapters for SBIG STL-cameras to have maximum opening for light path. These 2.7" adapters are huge compared to normal adapters I have used. I also got the long missed y-cable for my AP900GTO mount to replace ... http://www.kehusmaa-astro.com/2008/09/17/delivery-from-astro-physics Kävipä sitten sellainen vahinko, että jalusta ei mennytkään parkkiin viimeisimmän kuvaus-session päätteeksi, vaan seuranta oli jäänyt päiväksi päälle ja tämän seurauksena jalusta oli pyörähtänyt itsensä ympäri ja katkaissut deklinaatiomoottorille menevän kaapelin poikki! Samalla oli katkennut myös kaapeleita ohjaavaa kiskoa kannatellut nippuside, joten voima on ollut melkoinen. Parin minuutin 'hiljaisen' hetken ja ... http://www.kehusmaa-astro.com/2008/08/13/torni-toistaiseksi-pois-kaytosta
