Thanks Glenn I'm glad to see the continuing interest in this thread, I think many folks are intimidated with planetary imaging and think you have to have a big SCT or Newt to play...clearly you don't.
As for that "other" thread, I am starting to think "why bother?". Sometimes I just can't pass up a challenge

Clear Skies,
Brian

Do small bore sketches count? 150mm MCT with human eyeball.

.....maybe they don't 'cos it is an imaging forum Norme, but who cares - not me!?!

I'm glad you posted - makes me realise I should look at the sketching you visual obbing folks create more often!

Kokatha, thank you. Well...its....an...image, kind of, sort of.

Anyway, my apologies. This is an interesting thread and been running for a long time. Been following it and could not resist, it's what a "small bore" can do that's interesting.

With that, my regards...to all you imagers. As a visual observer, I appreciate your work and peruse your forum from time to time. One request, though. We observe the same meridian about 2 days prior to those of you in the US, can you get your images up in a timely manner, like two days before you take them? Please. (In jest.)

Hi Norme,

While this is an imaging thread, your sketch is terrific and gives us a really good insight into what visual guys are doing. I like visual work and try to fit some in to most of my sessions, many imagers do not appreciate the skill involved in picking out fine detail at the eye piece. Following your work in other forums I know what a skilled observer you are, so I'm glad you shared the sketch as a "special treat" here. Thanks!

Clear Skies,
Brian

This was taken from my back yard in Halifax on the evening of December 8-9. Seeing was incredible, but man it was cold. This is the first image I have taken in a long time. It is also the first with my new setup, a Meade LXD55 AR5 5 inch achro. I expect the quality of my images to improve a lot as I upgrade my equipment and gain experience. But this was a spur of the moment effort to serve as a benchmark for future efforts.



Equipment:

Meade LXD55 AR-5 5" achro.
Mead 4000 18mm Plossl
Antares 2.5X Barlow
Samsung S4 phone on the sketchiest improvised mount ever.

13 of 21 images stacked in Lynkeos and processed with PS.

I'm happy with my new telescope system, but the mount has a persistent wiggle that I've tracked down to play in the declination axis. Time for a rebuild I guess. As long as the wind is calm, it's no biggie. The mount is accurate though. Very happy.

The GRS was very prominent. Not captured in the image was the incredible seeing. Visually, Jupiter was breathtaking. The north and south equatorial belts showed incredible detail and variation. Every major cloud belt showed some detail and I could easily make out some of the minor storms. I even watched as Callisto and Europa "traded spaces" in their apparent positions. It was truly a sight to behold.

Enjoy!

Took these Nov 12 with pretty good seeing (could not get myself out of bed before Ios shadow appeared though). Images were taken with a Starfire 152, Barcon with ASI 120 MC. 15000 frames over 90 seconds every 4 minutes over about 90 minutes. At the end the sun had come up and the image quality deteriorated. Postprocessed with Autostakkert using the best 15% of frames (some also with PIPP), wavelets in Registax and assembled in photoshop. Had to compress it a little bit to fulfill the maximum file size requirements. I had posted this before, but thought it would fit here as well.

Thank you Brian, yea, sorry for jumping in there. I've been eyeing this thread with interest in small bore images since it began. Fascinating.

You are off to a good start there, welcome back to the imaging game. It will all get easier as you become more familiar with the gear and processing routine. Keep up the effort, I look forward to seeing more pix

Clear Skies,
Brian

Very cool animation Ulrich! Imaging with refractors is a very comfortable, low stress way to do business. That Starfire 152 is a fabulous OTA, do you have a motofcuser on your scope or are you manual? Thanks for posting

Clear Skies,
Brian

Hi Brian, thank you for your kind words. I am using a manual (feather touch) focuser. I do have a little JMI motorized focuser, but somehow prefer the tactile feedback of the manual focuser.

Since I like animations a lot, here is the animation
from 7th to 8th of December I did with my 150mm Mak.

That is one fine small bore image Michal
You just have to love those ZWO ASI cameras...

Clear Skies,
