Hello Pavel What ou are seeing is the straylight from the edge of the secondary, I wouldnt consider hat as an optical defect. You could put in an oversized secondary with the downside of unnecessary obstruction, or cover the edges of the secondory. In my opinion it also has its benefits as it takes energy out of the bright stars and keeps them from beeing saturated given quite nice star colors. What you have on the out of focus image at 5 o clock is clearly a tube current. Wolfgang

Thanks a lot Gerhard I think I might look into this a bit deeper in the future. Regards Wolfgang

Hello Matts Thank you very much. The images were taken remote last week. IR is indeed interesting, I used the IR filter from the Astrodon Johnson set. I mapped SII to red, IR to green, and OIII to blue, unexpectedly that produced a quite balanced looking image without wierd star colors. For the final image I just blended the RGB with about 50 percent in Photoshop. Anyway I think using IR on some object really leaves some room for experimentation. Regards Wolfgang

Hello Cristina Thank you very much. Wolfgang

Hello Everybody I didn´t get to image much recently but last week I got some data from the remote observatory in Namibia. M8 is a composite of 6 Channels IR SII OIII blended with a shorter RGB, the main information is from the IR SII OIII images which interrestingly looks quite natural itsself, anyway I added RGB to show the outer blue parts of the lagoon. The Second image is a plain LRGB of NGC 253 Both images were taken with the N12 on a DDM 85 in remote operation. http://www.astro-pics.com/m8tvm.htm http://www.astro-pics.com/253tvm.htm I hope you enjoy them.

Hello George Thank you very much. They have a SQM installed there http://www.sqm-network.com/index.php?option=com_wrapper&view=wrapper&Itemid=137&lang=en Wolfgang

Hello Everybody I just recently returned from setting up a friends remote observatory in Namibia. Here are some of the images I took during setup and testing. http://www.astro-pics.com/3372tvm.htm http://www.astro-pics.com/6188-tvm.htm http://www.astro-pics.com/ant-tvm.htm http://www.astro-pics.com/3576-tvm.htm I hope you enjoy them Wolfgang

Hello Jeffrey, George and Aggelos All three of you did a great job on that beautifull field. Wolfgang
