Well, i split antares tonight and the seeing was maybe 8.5/10. It was -3 degrees at 9.30pm. Boy it was cold. The peltiers did a great job getting the mirror to less than 1 degree by 8.30. The scope went out at 5.30 and the mirror was 10.5 degrees at that stage.
It seems I must have had low level bad seeing last few weeks. There has been no jetstream or not much clouds in that time, but temps have not gone negative. The last two nights have really dived! Is this temp inversion??
Anyway, am looking to see if cold cold nights mean good seeing.
I did a quick run at 10 fps and was very happy with the result. I will rgb split two from last night and this one.
A few images from registax, astra image and photoshop.
I made the same comment to another jupiter thread tonight, jupiter looks like the top has been processed differently to the bottom. please I am not bagging you, the image its brilliant, just that optical illusion I see. i will go hide in the corner now, sorry for mentioning it.. Pleased for your seeing too.
not sure houghy, i wonder if it the shadow causing the different hemispheres to look diff. Come out of your corner, you have 74 more posts to go tonight!!
Looks great, Davo! I don't think the two halves look different. Different colours , yes but that's because that's the way Jupiter is. Davo, I like the sandstonish colour schemes of your Jupiters.
Great photo & significantly more detail than mine taken a little later. Generous image scale - was this with the 10" Dob? What was in the imaging train?
