Jupiter, Europa and Io (03/08/21)

[Yawning Angel]

I been feeling vaguely disappointed in my C8's performance lately, and getting the itch to replace it! With last night being unexpectedly clear, I thought I'd keep the wallet closed and spend the night fiddling to really nail down the collimation

C8, x2.5 barlow, 174m RGB and 642BP IR

The result:

I might keep it after all 🙂

Yes I would, that's a nice image. The C8 has done well.

[Sunshine]

Yes, maybe you were too quick to judge as this is a great capture.

[Space Hopper]

Just shows you what a well ordered C8 is capable of.

Excellent work.

I had a C8 HD Edge a few years ago and foolishly sold it.

Always regretted it.

Very nice image, nice work👍

[morimarty]

Thats a very nice image Alex. Your framing is really good too. Collimation is really key in planetary imaging so spend plenty of time to get it spot on. The C8 is a very capable telescope take a look at Angie's recent post @U Cyg.

Ditto the collimation focus are the key + good seeing also, the C 8 is more than capable of capturing superb images of the planets i refer you to the post above!

BTW  very nice capture!

Thank you to everyone for your kind comments!

I'm so used to my maintenance free refractor I've been neglecting the C8

Yes, I found that I had to back everything off and come at the collimation fresh. Had one screw that never nipped up and the others far too tight...I'm just hoping it holds for a bit now 🤞

Focus...I have the Celestron motor on there, but I found a different technique that helped (I think). Instead of connecting it to Sharpcap and using the steps, I found using the native Celestron application and driving the motor at slow speed to be much more accurate (quieter too!)

Nicely processed that. Good capture

[Yawning Angel]

Now with added derotation

[U Cyg]

Nice images, this derotated image is showing much more detail.

It's a keeper, Alex. Great image; love the detail and color you were able to tease out with the de-rotation

[CraigT82]

Derotation looks nicer there, well worth the effort

[Pete Presland]

A fine looking image, given some even better seeing conditions and you will see even more detail.
