It does slew very slowly during final alignment ... Are you sure it's not moving ?

Hi @Gottzi

Just noticed you joined the group.

It's pretty quiet here but a few of us do post occasionally.

Saw the same thing last night, very hard to focus... Then it would drift in and out to a blur , yet the planet seemed fairly stable.

Lovely image !

Io being misshapen is most likely stacking induced.

Almost embarrassed to post but haven't seen many Jupiters taken on this year's opposition.

Very poor seeing through very infrequent gaps in the cloud.

C9.25 - 2 x Barlow - zwo ADC - zwo 224mc on an Ioptron HEM 27.

Best 10% of 8000 frames at 3ms.

Light hearted entry !

Waiting for Jupiter to poke through the clouds on opposition night 2022 ...

Handheld, low light mode on a Pixel 4a, slight highlights boost and crop in Snapseed.

Excellent 👌

Next time it's clear (🤞🏻) I'll double check but I'm sure on my SW72ed with 0.8 reducer it barely moves in and out while autofocusing using APT.

Nope, tried it. The reducer hits the face of the focuser and I get an error message. 

How far does the focuser move in ? Surely 5 mm is enough ?

If you have 5mm movement available it should work, try using shorter steps in calibration.

Mine only moves about 2mm in and out when focusing, might even be less ?

Seeing is everything, keep trying and one night it will come together ... Still a good image though.

It's easy in phd2, just connect the usb to the handset, run Ioptron commander, find the com port from Windows device manager , connect then run new profile wizard.

A little foible I noticed is that the mount mount track until you've done an alignment unlike skywatchers.

I bought the HEM27 recently, choice determined by available funds and a @FLO offer at the right time ...

I'm not really sure yet but I think I like it 🤞🏻

I'm still trying different guide parameters and learning the Ioptron commander side of things.

Attached a guide log from 16th sept. No imaging, just playing with different settings, guide assistant runs etc.

Pe seems to be about 40 peak to peak if I've read it correctly.PHD2_GuideLog_2022-09-16_203828.txt

I was just going to say that 😃

Also, if the RGB alignment tool won't run, re start registax in admin mode.

You could use Pipp to sort the ser file and let it centre, crop and select the best frames then use autostackert to stack.

Well, I've tweaked it in Photoshop and not sure if I've over or under processed it. Pleased with the first light image though. 

Celestron 11inch SCT, Zwo Asi 224mc + Baader Neodymium filter + ADC, 9,000 frames with 25% stack using autostakker3, 

In registax try the RGB alignment tool, it should make things a bit sharper , the colours  look slightly misaligned.

If it won't open try running registax as admin.

Great shot though.

I'm going to have to learn WinJupos me thinks.

Maybe another way to approach this Is ... how many good frames do you need to stack to get a good image deep enough to sharpen ?

If for arguments sake 1500 frames gives a good enough result, why go further ?

Quick update, nothing exciting managed a bit of planetary between the clouds last night.

Extended legs about 1/2 way which was enough to feel pretty stable, I'll make something to hang the battery pack from for extra security eventually.

When focusing it took about 10 seconds to dampen down vibrations ( was about 5 on the heq5 )

Also caught Io bottom left corner.

Yes. I am! Is there a cure?

Yes, but it costs money 🤣

And now you're hooked 🤣

Rough idea of size comparison to AZ-Gti in eq mode ...

You've done well there ! Banding on the surface and hints of Cassini division 👍🏻

Zorin is a nice easy Linux to try, you can load it into a thumb drive to try it out.

That's excellent !
