Jupiter from the 23.4.2017, RGB and OSC

[Pete Presland]

Some pretty decent seeing conditions last night, wasn't expecting much to be honest!

First image is 7.5 mins RGB with my Asi120mm, derotated in Winjupos. The second is 3 mins OSC with my Asi224mc. Both with the C9.25. I could do with upping the image scale slightly maybe with the Asi224mc. Both stacked in Autostakkert2.

Very nice. Lovely subtle detail visible. Next time I will try 3 minutes with the ASI224MC, instead of 90 seconds I used last time

I might have a go at derotating it as well, I guess 3 minutes at getting on for F20 might be getting to the point of blurring some of the detail.

Very similar to what I got Pete, nicely done you've pulled out some good detail despite the unpredictable conditions!

[bottletopburly]

Nice work pete  very nice

[xtreemchaos]

cracking shots Pete, great detail caught mate. thanks, charl.

[Tommohawk]

Agree with everyone else - nice detail and like the processing too.

Are you using any barlow - would a x2 be too much do you think? Also wonder why the ASI120 and 224 images seen different scale when pixel size is the same.

Can I ask what frame rate you get with the ASI224, and is it USB3 or 2?

Sorry - lots of question!

[Pete Presland]

I am using a X1.8 Barlow with both cameras.

The image scale difference Is down to the filter wheel increasing the Focal length with the Asi120mm. Frame rate for the Asi224mc was around 120 fps.

Very nice images Pete. Lots of nice detail coming through.

Pete any chance of posting the  FC log file for those captures 

cheers dave

No problem will do tonight

Was that for mono and osc?

Yes one shot colour 

[bottletopburly]

Wondered what OSC stood for ? Every day's a school day ☺️

Two lovely images Pete, But the mono rgb is the one for me.

[astroman001]

Interesting comparison. I bet with a bit more image scale and colour tweaking, that there would not be much to choose between them. I use an ADC with the 224MC which at these altitudes is a must.

Processing is so much easier.  Seeing has to be really fantastic to differentiate between RGB and OSC with ADC.

Best regards

Peter

Beautiful images, Pete, with some very appealing processing.

Pretty Jupters! Thanks.

[U Cyg]

Lovely images Pete.  I don't see a lot of difference between them, but I think the RGB just wins.  I agree with Peter's comments above about image scale with the asi224.
