Looking good so far! At least I'm not the only one to grab the wrong shot. The more of these huge Sharpless objects you run the more I need to find room in the budget for a wide field something. Budget just took an unexpected hit so guess it will have to wait. More time to figure out what I want. Got some sky tonight. Horrid humidity so transparency is down. And for some reason the cosmic ray hits have returned. Last April and May they were hitting nearly every shot then suddenly were gone. Now they are back and far worse. I tried to get the nova again tonight to see if it is changing and while it wasn't needed I had the guider running. Cosmic rays were hitting in the guide box which is only 35 pixels wide! The guider started chasing them so turned it off but the individual frames have dozens of hits in one minute. We did have a nasty thunderstorm last night. Did something come in with that? With the big chip they are all over the place. This will be a real test of sigma reject! Ever hear of this? No they aren't Perseids. They are going all directions. They cover 8 to 10 pixels at most. If the observatory starts to glow I'll know why! Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |

All these look nice Richard... I guess you could spend the rest of your time
on Earth shooting the detail in the Sharpless objects.... in Ha anyway... -- Regards, Doug W. www.photonsfate.com "Richard Crisp" wrote in message ... this is from a 6x7 SMC Pentax 200mm f/4 lens used with an FLI CM10 camera with a Baader 50mm x 50mm Square Halpha filter in an FLI CFW4-5 filter wheel with FLI PDF focuser http://www.narrowbandimaging.com/sh2...sq_ha_page.htm it is a total of 16 x 20 minutes or 5h 20m |

Another great image. This is definately one I have to try too. It will be a
tight fit with my camera at 200mm focal length.
