    Here's a quick process of last night's M31 data taken with the Sky 90 array. This is 9-hours worth of 20-minute subs. Weather permitting I will go for a LOT more data on this one and may start off with 30-minute subs Greg

    Got out for a couple of hours last night before the Moon rose. This is 11 x 10-minute subs using the Hyperstar III on the C11 with a Trius 814C OSC CCD. Noel Carboni processed this one as it was very difficult to sort out (flatten) with a large bright nucleus in the middle of the frame. Greg

    That looks awesome mate. Have you opened up the starlight express? Those types of plugs may come with fusable resistors which pop if connected to power. Worth opening up and having a fiddle if you are handy with some electronics. Sometimes it is just a visual inspection to locate a burnt out component. Ray

    Switched out my Celestron CGEM for an iOptron CEM60 mount which I now use for imaging. took this of the Eastern Veil over about two and a half hours at 15 minutes per exposure with a Stellarvue 102CV scope and QHY8L camera.

    I had a Celestron CGEM for about 8 years and it performed pretty well. Guiding graph was a bit jagged but within the first row of parallel lines on the graph. It also began to chatter when slewing so I decided to try an iOptron CEM60. I had gotten an iOptron 25P for portable imaging and was very impressed with the smoothness of the guiding and operation so I thought its big brother might be good. upon setting it up, by mistake I plugged my guiding camera into a power port. from there on I couldn't guide at all, so thinking the mount might have issues I sent it back to iOptron for repairs. They fiddled with it but found no problems and sent it back to me. I tried connecting the mount directly to the computer for guiding using a GPUSB box and PHD. Works fine and guiding is exceptional. They have a good polar alignment scope and illuminated rings to place Polaris in the right spot. Seems to be nearly perfect. I took the viel nebula using 15 minute subs for 10 exposures over a two hour and half period of time. all frames had perfectly round stars. guiding graph is attached in photo. So judgement is, its about as good as it gets for a mid priced mount so far, and super smooth operation. Not sure what to do with guiding though the camera to the mount as that doesn't work so I think I may have fried a circuit in my Starlight Express guiding camera, but it does send images tot he computer that I can use to guide using the GPUSB box and cables.

    Geezuz! I'm not sweeping that up. Great capture of dark neb, which is actually quite a hard thing to resolve. Nice work Prof. Ray

    Lots of dust in there. Shane

    Not in Pasadena where we live, but along the coast about 50 miles away its horrific and smoke is everywhere. this area of the coastal plain has a history of burning to the sea when off shore winds pick up for centuries, but now people have populated the slopes so its dangerous. I was out of the imaging business for nearly six months after changing out my mount and getting the new one up to performing. when skies clear I hope to do more.

    I spent the night at Brimham Rocks in North Yorkshire shooting another "Holy Grail" time lapse (day to night to day). Although it is a lovely area to shoot from scenery wise, it wasn't as dark as I was hoping and there was a fair bit of light pollution from Harrogate and the skies were a bit milky so the milky way didn't show that well, to top it all I accidentally tripped over one of the tripod legs when I was checking on batteries so there is a jolt in the time lapse. I've also included a couple of stills taken with my Fuji GFX50S and some drone footage from the morning taken with my Mavic Air. I used my Sony A7Sii and Samyang 24mm f1.4 lens on a Dynamic Perception slider and Pan and tilt head. In all I took about 2,200 images for the time lapse. The video can be seen at the link below in HD and 4K https://www.youtube.com/watch?v=5Zwrkua_AfM

    Epic mate. I almost got some photons tonight but just as I was doing my PA cloud rolled in. At least one of us is getting some telescope time. Ray

    Just for a laugh I combined some old Canon 200mm lens on Canon 5D MkII data with the recent Sky 90 data to see M31 in perspective Greg

    Not fair, jealous, envious, quite upset. All I have is lingering altostratus this week. Some spatterings of blue sky but mostly wispy high altitude cloud. Now that I have vented about my problems, I'll exercise some self control and move on. Great data for such a short run Prof. Awesome little rig you have there. However it looks upside down from Perth, Australia. Can you flip it? My necks hurting. Ray

    Incredible Prof. Well done. Ray

    Actually - VERY deep images of the region show it's full of red emission, probably all coming from the Heart nebula which you can just see top left. Greg

    I didn't refocus during those 110-minutes, but it was coming up to refocus time Usually need to refocus the Hyperstar every hour on a cold night. Greg

    Epic effort Prof. Man that focus must have been sharp for the detail in those dust lanes. How often do you need to refocus? Ray

    Beautiful Prof. Would have been a nice intense nebula in that location before those stars formed and sucked up all the gas. Ray

    I live on a mainroad and each car that passes makes my 4 metre scope shake like a mother. The shake effect seems to be worse on my planetary (this camera) than when I shoot on my large format QSI. I really need better dampening technology in the ground for my pier to prevent those vibrations travelling upward. Anyone know what the straight gully's are caused by in the first photo? Below - Ray's X-wing fighter is clearly shown on the right handside here. I managed to snap its shadow as it was chasing an imperial tie-fighter smuggling the data of a rebel stronghold. The shaky-ness of my pier causes my histogram to spill over and cause the excessive white point. Ray
