    Here is a 2-frame mosaic taken using the Canon 200mm prime lenses and the Trius M26C OSC CCDs. It is centred on the Crescent nebula in Cygnus. Needs more data. Greg

    That's a ton of stars. How many stars have you captured in all your photos? Be easy software to write where it just looks at all your image files without even opening and counts them. There is already software that counts stars in open images, and similar software is used in biotech to count cells. Ray

    I have grown to appreciate planetary imaging more over the years. The planets change. Rings up, rings down, cloud pattern changes, an occasional asteroid or comet strike, (if one is lucky enough to be imaging at the time...) Most importantly, being able to get some imaging time and still get to bed at a decent hour. As the topic dictates, here are a few of Saturn this apparition. First out RGB on 09/01/22 Played around with mapping the channels to different colors in this one. Interesting but ehh... This one from 09/08/22 First couple of images using a ZWO120mm. Last one with a ZWO1290. The results don't seem any better to me with the 1290. I am going to revisit my old Celestron Skyris 618M for comparison on my next outing. It has the same sensor as the older DMK21AU618.AS Anyhoo, sure is fun. Tim

    Still using the C9.25. Love to find a bargain on something a little bigger. I really think the images I am getting are at the threshold of what I can do with this aperture. Tim

    Another 200mm lens 2-framer with only 2-hours of 5-minute subs. Greg

    Some beautiful structures in there! Ray

    Geesuz Prof, that's a lot of stars!

    I found some old 200mm lens data of this region from 2015-08-08 consisting of 8 x 30-minute subs. I added this to the previously shown 10.42 hours of exposure time to give this final composite image of 14.42 hours. Probably enough on this one with that setup. Greg

    That is one dense starfield. Great image! Tim

    The central bright star is Sulafat - move to the right hand edge at the 3 o'clock position from Sulufat and that is Sheliak - these are the two bottom stars in central Lyra. Move 3/4 of the way from Sulufat towards Sheliak and that is M57 - the Ring Nebula. This is a composite single framer using the Canon 200mm prime lenses and the Trius M26C OSC CCDs. A total of 6-hours and 20-minutes using 10-minute sub-exposures. Greg

    I loved that movie, 'The Full Monty'. Definitely a classic! Amazing image! It's so hard to say when enough, is enough, on a target like this. Tim

    And with the Celestron Skyris. I think, I prefer the Skyris over the ZWO models. Opinions? Tim

    Incredible. I'd love to get my C14 onto that nebula lower centre. Ray

    This is a 2-frame mosaic of the Cocoon nebula region using the 200mm lenses and the M26C OSC CCDs. 5 hours of total exposure time using 10-minute subs. Greg

    This is a 2-frame mosaic of the Ruchbah region in Cassiopeia using the Canon 200mm prime lenses and the Trius M26C OSC CCDs. Each frame is 2.5-hours of 10-minute subs. Greg

    This is a 2-frame mosaic of the Caph region of Cassiopeia using the Canon 200mm prime lenses and the Trius M26C OSC CCDs. Each fram is 2-hours of 10-minute subs. Greg

    Here is a 2-frame mosaic using the Canon 200mm prime lenses and the Trius M26C OSC CCDs. This is Castor (blue star at the top) and Pollux (the yellow star at the bottom) the Twins in Gemini. 6 hours and 20-minutes of 10-minute subs went into this one. Greg

    This is a 2-frame mosaic using the 200mm lenses and Trius M26C OSC CCDs. It shows M44 (the Beehive Cluster) sitting within the "Stargate" formed by the 4 central stars of Cancer the Crab. Each frame is 3-hours of 10-minute subs. And to top it all, over to the left are two Carbon stars, one in the middle and one in the lower left hand corner. Greg

    NA & Pelican nebula on the 200mm lenses and M26C OSC CCDs - 17 x 20-minute subs plus 19 x 15-minute subs giving 10.42 hours in total. Greg

    Totally agree - hard to believe it's real - that's what a short focal length does for you Greg

    Its quite mind blowing when I see all these stars in your pics Prof. Kind of hits home what must be out there. Ray

    Here's a big crop to just the Double Cluster and Stock 2. Greg

    A reprocess from 2016-11-07 the Double Cluster & Stock 2 in Perseus. This is a 2-frame mosaic using the 200mm lenses and M26C OSC CCDs. A total of 6.5 hours exposure time using 450-second subs. Greg

    Yeah - the Moon and Orion do the same thing as well. Fairly difficult to explain seeing as the Earth is flat Greg

    Very nice Prof. But it is upside down from Australia. Ray

    First night out imaging for the new imaging season last night and fired up the C11/Hyperstar 4/2600MC Pro CMOS system to image M31. Got 52 (out of 60) subs at 3-minutes per sub. A lousy process - byt hopefully Noel will do better later. Greg

    This is a 2-framer with the 200mm lenses and the Trius M26C OSC CCDs. The frame on the left is centred on IC2087 and the frame on the right is centred on SAO76573. This dusty region is just a tiny part of the massive Taurus Molecular Cloud. Each frame is 10-hours of 20-minute subs so this is a 20-hour exposure image! Greg
