Star spikes rotated a bit for obvious reasons (if you look at the original). Greg

Nice work Prof. Ray
-
Its amazing with that light pollution you can capture those filaments. Nice work mate. Incidentally, what are your LP levels there? Ray

Procyon & Gomeisa with the Canon 200mm lenses - a 2-frame mosaic. Greg

Western Veil NGC 6960, Stellarvue 102SV refractor, 10 exposures at 15 min each, QHY8L camera, iOptron CEM60 Mount, from Pasadena California, "Light Pollution Central".

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

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.

I know this feeling. When I bought my C14 my Losmandy G11 couldn't guide. Took a year or two improving the gear boxes, motors, etc, until I finally took the plunge (a big plunge) and picked up an AP1600GTO. A good mount makes imaging enjoyable. Ray

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
-
Very nice indeed. I wish I could afford to upgrade the mount, maybe one day. Thoughts on the Ioptron? 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 wanted to put a reprocess of this dusty region in Taurus on here - but it looked rubbish So here's the original. Greg

16 Hours at Brimham Rocks timelapse
Radar replied to Paramount's topic in DSLR and CCD Astrophotography
Great video and the location looked very cool (Brimham Rocks). Ray -
Nice colour and filaments Tony. Are the fires anywhere near you? Ray

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

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.
-
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

Noel pulled out all the stops in processing this one. I think he is trying to encourage me to get the frames off the top and bottom of M31 I need no encouragement - next clear sky - I'm out there Greg
-
Very nice mate. 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

With a full Moon (red circle) for size comparison. 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

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
