Hello Roland,

Focus is always a ? for me, as unless I try best focus and were to then process on AVI to check...it is just what looks best on the laptop screen.

I typically can see very little detail in the bands, but if the GRS or it's wake is visible I can generally see a little detail.

Here is one of the better single frames of the last stacked image that I posted...and it looks just about what I see on the screen when I am focusing and capturing AVI's.

Looks to be windy tonight, but if not I'm out for another try and will see if the TouCam will capture color???

Best Regards,

Preston

Hello Preston,
a single frame of my video of January the 17th done with my 4" 1100 mm achromat.

I did 440 pictures per video and the Great Red Spot was nicely seen in the live view.
I'm curious to see your Jupiter in colour. That would be great.
Clear and nice skies,
Roland

Awesome animation Proky! That color camera does a good job, just like your telescope! How did you record these images? As SER-files with debayering disabled? Just asking, as I'll recieve my ASI120MC this weekend ;-)
Thanks!
Rik

Hi Roland,

Are the 440 pics part of a larger stack? Im recording about 2050 frames over 3+ minutes and then using about 50% or 1000 frames for the stack.

Your single looks like a very good night if that were on my laptop screen when focusing...normally, I am trying to guess what is best focus on the surface of the planet unless the GRS is in view.


Best Regards,

Preston

Dear all:
Here is my best jupiter image. I am still a novice in planet astrophotography.

Jupiter 28th.01.2014. Skywatcher 6"F5 Reflector, ASI120MC, 5X Barlow Meade

Hi Preston,
thank you, Yes, the night was nice. I looked through the eye piece and saw nice structured bands and the Great Red Spot and thought that could be a chance for a nice short video

No, I just took 440 frames at all in that video (about 15 seconds). I took this video without motor drive (I think the battery was empty) so after 15 or 20 seconds Jupiter went out of the view. The next time I will try 2000 frames, too. Maybe that improves the image quality.

And I will follow the advide to use the moons for focusing if the seeing is bad.

Clear skies,
Roland

Hi Rick. I use avi files from SharpCap. Debayering is disable.

Sorry I've been out of the loop for a bit, you guys keep cranking out cool small bore images and this thread is still on fire Nice work out there Joe, Dave, Roland, and Preston; you guys are getting it done! That is one beautiful Jupiter Roberto, that AP magic is tough to beat. And welcome aboard bill44026, a very nice contribution from you and your Skywatcher
I feel like a real slacker this season, you all have been carrying the load so I thought I should contribute something too. Seeing has been just terrible here this winter, but back on the 11th of February I got the TEC 140 out and captured some video. This image was acquired with the TEC 140, TV 5x Powermate for f/35, and my trusty TIS DBK21AU618 w/ a Baader UV/IR cut filter.
I promise to try and not be down so long in the future if I can possibly avoid it, I really like to keep up with everyone's contributions. This thread has opened a lot of peoples eyes and convinced them that they can play this game even if they don't have a huge SCT or Newt, and that is because of the members who have shown their work here...you folks are terrific!

Clear Skies,
Brian

We've only had 3 or 4 clear nights in the last 6 weeks. Finally got a decent night of seeing the other night. It's also the first time I've seen the GRS since December!

That's another nice one Evan, one question for you. Stacking the Barlows gave you a 4x magnification, but the image scale looks smaller than I would expect. Did you reduce the size of the final image at all? Just curious...

Clear Skies,
Brian

Yes, I did.

I'm using RAW video mode with my Canon DSLR. That exposes all of the sensor noise to each video frame (no NR is being done).

By stacking barlows, I'm increasing the image scale. My scope doesn't have the resolving power to see any more detail with the stacked barlows.

However, by increasing the image scale, stacking/processing, then resizing back down to what I'd get with a single 2x barlow, I can eliminate even more sensor noise, while retaining fine detail.


I've done a direct comparison between a single 2x barlow and stacked barlows resized (the videos were taken within a few minutes of each other) - the stacked barlow image had a little less noise and a bit more detail.

A single 3x or 4x barlow (or extension tubes on a 2x barlow) would be more ideal, since you would have fewer optical elements in the light path. I may try using a T-thread extension someday to get the same magnification with a single 2x barlow.

Hi all,

I thought I'd make a contribution to this thread. These were shot with my EON 120. Seeing was shaky and Jupiter was less than 40 degrees high. It shows how much detail can be caught with a "small" scope. I don't think I was getting this much detail back in 2003 with my C8 and toucam camera. How far we have some!!

Hi Paul, it's nice to see you here Very good image, and the color rendition nice. I notice a distinctly red biased base image when using my SW100ED, do you also see this with the EON? With less aperture it is tricky getting good color saturation, something we often take for granted with larger scopes...

Clear Skies,
Brian

Quick single sub - Pentax 105SDP, 5x power mate and 383L without guiding or polar alignment. The 383L is usually too sensitive but this is with the light reduction of the 5x and amp off (no cooling running either).

Very fine image for a 6 inch Proky...and your animation is just so Smooth!!!

How many frames were you capturing versas stacking for these images?

Best Regards,

Preston
