ASTRO: Returning from the crypt and three first lights
This has been a long spell of no imaging for me. I last was able to image on
the evening of Jan 1 Since then I have been inundated with either bad weather, too many chores or international travel. Saturday things changed. I got to test the AP155EDF with the Proline 39000Mono finally under some decent skies. Seeing wasn't great but it was clear and dark. I used an Halpha filter and got this shot of the Rosette, a bit late in the season. I managed to get 14 x 15 minutes. It was first light for my new AP guidescope. I had a bad storm in January that blew over my system in its cover. The only things damaged when it hit the rain-soaked ground were the drawtube for the guidescope (since straightened and a replacement procured from AP) and the scope cover, that I had to cut in order to disassemble the system. The wind had no problem blowing over the system but I could not lift it as a single piece so I had to cut the cover in order to disassemble it. In the meantime a friend sold me his AP guidescope so now I have two of them. We had a newborn on Saturday morning. So this little fellow also had "first light" on Saturday. It was about 4-6 hours old when the photo was taken. The 39MP is a bit low on the QE side at 22% so at 3.5 hours the data is a bit thin. Still it is fantastic to have such nice resolution over a largish FOV. I get the same FOV with this AP155EDF/PL39KM as I do with the KAF8300 at 400mm or the KAF3200 at 300mm, but at much higher resolution. http://www.narrowbandimaging.com/ngc...LI_ha_page.htm |
