The 6" (1000mm FL) is the bottom end (probably below the bottom end) of what's required for planets. I think the PowerMate is working as it should? Also, the atmosphere close to the horizon doesn't help!

Oh yeah, I keep forgetting you're up at the Artic Circle. Haha

Thanks Craig. Oh if it were only that easy! No I have a (relatively) new telescope. I used to use a 127mm refractor. I replaced that with a Meade 12" Catadioptric telescope with almost 3 times the focal length (2430 vs 952mm). I also used a 4x powermate and a new camera. I used to use an ASI120mm monochrome camera with an rgb filter wheel. I got good results but I wanted to shorten up the workflow and the post processing so I got an ASI224mc color camera which also supports USB3 as opposed to USB2 so I get a much better framerate. Now the only issue is at 47 degrees north, Jupiter is hanging out at 27 degrees (max) above the southern horizon (declination: -14deg) so the "seeing" is just not very good. Unfortunately it gets a lot worse next year when Jupiter's declination will be a miserable -22 degrees, which is where Saturn is currently. Anyway, when Jupiter turns the corner in 2021 and starts crossing higher than it is currently, that's when the good imaging starts. By 2024 it will be crossing at +20 degrees declination. Should be some great imaging then. I think this image is the best I've done with Jupiter to date but I expect much better images with this telescope as the planets get higher in the sky.

Interesting you used the new ASI camera and scope. The EXIF said you were using a Nikon camera and $13,000.00 Lens. Hahaha for EXIF.

A buddy I have on the west coast complained the image was too blah, so I brightened it up a touch...

OMG Brian, that is spectacular.

PS I just saw my other post, sorry.

I shot this a few nights ago with my usual setup of Celestron C8 and CGEM mount.
I imaged with the Celestron 236C CMOS at 640 X 480 and shutter speed of 1/125 seconds.
I ran a 2 minute video capture at 120 FPS and stacked 80% of 12,400 frames.
Registax6 for the wavelet clean up and Photoshop to adjust white balance and saturation.

The second shot is the same video but I only used 10% to stack.

More detail with the 80% but less junk in the 20%...

Jim

Nicely done Jim.

It's been a while since I posted here. I was away for some time but I'm getting back into the astro world again, starting off with the planets, making plans for going off-site to do Mars in July...can't wait! Anyway, Jupiter is currently at -14deg declination which means, from my vantage point at 47deg N latitude, it's max crossing altitude is only 27degrees above the southern horizon. Pretty low so the seeing generally isn't very good. Never-the-less, I must have caught it when the currents were stable and the spirits decided to take pity and let me have this image. It's the best Jupiter I've been able to do to date. I can't wait to catch the planets higher in the sky. Unfortunately, for Jupiter that's still a couple of years away. 2024 will be a good year for imaging that planet.

Beautiful very nicely done. Did you actually use a Nikon AF-S Nikkor 180-400mm Lens to shoot this???

I’m looking for a good, simple intervalometer that can schedule hundreds of images for star trail photography. Any suggestions?

You are looking for something simple.
Here is a simple one for a Nikon DX camera I used for my D5300 camera.
You just need to do a search at eBay for your camera type.
I believe these are good for up to 399 shots.

Shot several minutes of video (5000+/- frames) of Venus this evening with a Celestron 6in. SCT, 2x PowerMate (2000mm FL) and the Tiny1 camera, Celestron Evolution mount, unguided.

The result is about what I expected; a yellow blob with indications of phase...

Enjoy!

Nice shot Brian. Could it be the Power Mate that is causing the blurriness?
Or is the 6" just not enough scope to pull it in?

Getting my equipment setup, checked setup on M5. This is 24 lights of 80 seconds with AT10RC with QHY12 OSC.

Beautiful work Brian.

I used my stand by Celestron C8 and the CGEM mount.
I shot with the Celestron 236C color Cmos at 1/120 second at 640 X 480 and 100 fps.
I stacked 25% of the frames and did wavelets in Registax6.
Cropped and tried to balance the white balance but not sure how close this is.
Jim

Great job with the 8" Jim.

Thank you Craig.
I’ll be thinking about you while I try to image the Squirrel Nut Zippers.
This is our headline band for the kickoff to Summerfest. I have to work until 7 but should be able to image the band before them and the headliner. Going to be a long Saturday night.

Jim

Have fun with your gig Jim.

Rotated 90deg. and cropped

Very nicely done Tony, what scope and camera did you use to get this.
Thanks

Also shot in Mojave. ~5 hours. I only had the exposure set to 400, probably should have bumped that up a bit. I did not process this with the "smoothing effect", but I added a radian blur of 1 in PS.

Very cool Brian, you're having way to much fun out there in the desert. Wish I could be there too.

Reprocessed the original AVI with Autostakkert2 selecting 30% of 9,000 frames. Moved into Registax6 to adjust wavelets and sharpness.
Resized in Photoshop and noise removed with Photoshop Gausian blur.
All in all, I like this shot.
Jim

Very nicely done Jim. I'm off to the mountain Saturday night and see if I can get out from under the Marine layer.

Give are take a few days...it has been 5 weeks since we had a night with limited clouds and no showers predicted. Today - there were none - so I fired up the Vixen with the Quark Chromosphere - along with the ASI174MM-C camera and took close to 30,000 frames of the sun - surface, proms, and flats. So now I have something to process.

....and tonight - if the clouds steer clear - the wide field on the right will be fixed first on the Hercules cluster, M13 - then on to Rho Oph for some narrowband.

You sure can't tell it from the pic but I only have two wires from the scope now....data and power for each. No more snags or worries during an unattended flip!

Good luck Ed hope to see the results from y'all.
