Jupiter 21 July

[IanL]

Had some better seeing tonight but only just. Knocked of 19 AVI's and this is the first one done. Happy with results so far but i feel that the image is to grainy and also lacking fine detail. But i'll work on that another day. Just take the seeing while its here.

PS, :thumbsup: Mike i followed some of you instructions with regestax made all the difference.

Cheers

Great effort. Looks like an improvement! More frames will get you less noise.

Will done Ian, very nice work! I envy the clear skies and decent seeing you've been having.

[IanL]

Mike the seeing has been terrible. Jusr sort of got a break last night from a howling jetstream

Hi Ian

A very nice image Ian – I don’t know how you manage to get such good results without using a motorised focuser, even though the Mewlon focuser is quite smooth with minimal image shift!

I was out last night too, using K3CCDTools to explore the periodic error on my EM200. I poked the Mewlon 180 with Televue x2.5 Powermate and DBK 21AF04.AS at Jupiter part way through the session (21:52), as there were some reasonably good moments of seeing as I watched Nunki on the K3 display. So, just for comparison, here is a twin Mewlon shootout across Bris Vegas.

I reckon the seeing was more like 6/10 for some good periods, although later on it appeared to deteriorate to maybe 5/10 as I chased down a few doubles? If only there was a device we could plug in and use, to derive a more objective and standarised assessment of seeing?

The image is a stack of 644 from 1600 in Registax, with Wavelets 1=30 and 2=15, no other processing.

Looking good, Ian. The second one especially has quite a lot of detail.

Hi Dennis,

I am just enjoying making up for lost time due to clouds in the uk.
The more i am out the more i am learning. Although i am 10 feet away from a main road which is a pain as cars come over the hill their lights refect off the roof of my house which i am sure is not doing the imaging any good along with a garage 100yards away. But i am still fighting with the mount, registax and a host of other things. But enjoying it. Thats the main thing for me is to enjoy it. Just for comparision here is an AVI ran through registax and used the same wavlets as yourself. 10:25 and about 975 frames. Nothing else done to the image

Hi Ian

You are catching some nice detail in your Jupiter images now – well done for persevering in spite of the less than ideal seeing in Brisbane this season.

What Barlow are you using with the ToUcam – I see your image scale is larger than mine with the TeleVue x2.5 Powermate? Another factor for the size difference could be the ToUcam vs. DBK, even though they appear to be the same chip?

Or, probably the real reason, you are a smooth operator and I am a klutz!

Cheers

Dennis

PS - How is the collimation holding up?

[IanL]

Orion barlow 2 or 3 times i think it is.
Just checked shorty plus 3 element 2x barlow
Collomation is holding well. Although i am going to fine tune it as i feel that small detail on Jupiter is missing and that along withe the elements could be at fault

Thanks Ian, I originally suspected you had a x3 Barlow plugged in there due to the image scale.

Cheers
