Saturn 2nd April

Seeing was very up & down (ranging 2-6/10) but while I thought it was 'up' decided on an F35 capture. In the shot is Tethys left & Enceladus right.

Thanks Stuart.

Oh yes, chaffing at the bit to get the 14" up & running again - I'm having collimation (the holding of!) problems as well as EQ6 RA problems right now although I'm nearly sorted..

Comments regarding images with ringing and banding are normally negative, but in this case: nice rings and bands! Well done Asi - can't wait to see what you can do with the 14"!

Your mounting the flextube on the EQ?

Thanks guys. Well it's a home made 'flextube mate. Have you not seen it? Collimation is done by 2 wires with turnbuckles wrapped around the OTA 180 degrees, 180 degrees apart.

Very nice despite the conditions John. I can see the Enke and even detail in the B ring, maybe even the Maxwell gap? Having Saturn higher is making for better imaging prospects. I really must get my act together.

Ahhh I have seen that pic but did not realize it was your SW Dob! Looks fantastic John what a transformation! Tube thermals should not be a problem. That definitely needs pointing at Saturn!

Yes Paul it's about time mate, get cracking

Thanks Trevor. I actually set up twice. The first run was passable seeing but after stacking a few, deleted the data packed up & called it a night. 30 mins later I setup again determined to get something better. I run a lot on intuition & gut feeling these days..

Yeah, no thermals Stuart although it still takes a lot to stop that big mirror from shedding heat & creating that barrier layer which is just as damning in effect as thermals. I hate newts man..

This is an interesting result to me, interesting because it was a test using 60FPS with a 30% full histogram. Unfortunately the image scale has to be around F20-22 & no more, but in reasonable seeing, Saturn should be imaged at a minimum of F30 to gain the desired resolution. The point is, don't be too concerned about sticking to 'rules of thumb' about full histo's on THIS target. On Jupiter, the histo rule is set in stone IMO.

Another two results from the same date. Seeing wasn't overly good at this stage so I stuck with F22.
