Saturn is badly placed this year, being so low down, and will remain so for another 7 years, or so. It's a shame, because the rings are nicely open. By the time it is higher in the sky, the rings will have tilted away from us. In the year 2030, when it will once again be high in the sky, with the rings open seems a long way away . . .

Plenty of time to practice!
I use an 11" Celestron SCT (CPC 1100) on an equatorial wedge, with an 80mm refractor as a guidescope. They are housed in a 2.2m Pulsar observatory. I use a ZWO ASI1600MC for imaging.

Hi Aratus thanks for the reply I will give another go and see if I can get a better image as I can see it every night in the south without obstruction.
Thanks

How are you imaging? Are you taking single shots, or can you capture a video for subsequent stacking and processing? Apologies if you've said elsewhere.
Scopes: Meade 8" SCT, Skywatcher 127mm Mak
For imaging: Pentax K5, Asda webcam, Star Adventurer (new toy)
For companionship: Mid Cheshire Astronomical Group.

Hi I am using a gpcam v1 mono camera and I stacked 200 frames and use autostark.Then I used regitax for the wavelets and finally use gimp to enhance the image.

The image is nice and sharp, with all the features you might expect like the 'A' and 'B' rings, the equatorial belt, and the planet's shadow on the rings. You might like to try using a barlow to increase the size, if you feel you have enough light to spare.

Increase the exposure, and see if you can bag Titan, and/or some of the other satellites.

Hi Aratus thanks for the comments,I will have another go when it is clear.I am going to try and get to 1000 frames as it took me 2 minutes getting 200.
Thanks

Good idea. Are you manually taking individual frames? You might consider making a video (Avi?) file which would given you more frames per second.
Are you using all the frames you capture, or do you pick and choose the best?
If you took a 1000 frames and used the best 200, you would get a significantly better image.

I notice that Saturn is begining to slip over to the south west now. I really need to get out and observe it myself!
