Double transit Europa and Io

[Pete Presland]

This mornings double moon and shadow transits, Europa and Io. Just the "L" channel for now. C9.25/ASI120mm,742 filter. 180seconds, stacked in A/S2.

Great capture of a double transit. Moons sitting beautifully over their shadows close to/at opposition. Plenty of detail on Jupe. Clouded out here...inevitably!

Very nice capture, look forward to seeing the final result. I was observing this last night so it's nice to see confirmation of some of the detail I saw. Thanks!

Excellent work. I stuck a webcam on my mak but gave up and did visual with the dob. Now I can see some of the fleeting details I was unable to draw. Thanks for sharing

Great capture Pete, haven't looked at mine yet but don't think it will be that good.

I tried the focusing from a distance, you suggested neil, it works very well. Still not good with the x2 barlow,  but I have purchased a x1.8 and will give that a go.

A great double transit capture Pete!

Very nice image. Lovely detail.

Nice capture Pete.

Well captured Pete! I've found 1.5x drizzle in as!2 works very well on the Jovian moons which might be worth a try with your shorter FL.

Thanks i have never tried the drizzle option, I will give that a go tonight!

Nice detail in that L channel, hope the seeing held for the rest.  Was that taken at native focal length?

It was, around 2350mm maybe a little more with the focuser and filter in position. I tried using a x2 Barlow, but the FL goes up to 6000+ according to Firecapture, focusing seems very difficult. I have recently purchased a x1.8 so I am going to try this next time.

Yes it does Peter, to get it to work at higher FL can take more time. sometimes I don't nail focus the first few captures myself, especially under our UK skies. If you keep at it you get better with higher focal length, using this tech. But ii will say its what I prefer, which is not everyone, some prefer a motor focus and no wobble, I can see why

What I have been doing is using 2x-- 80mm Extension  tubes.

This give me f15 on my C8. A  Barlow gives me f20 ,which is

a bit to much. Easier to focus as well.  Found better images,

without a I/R cut filter. It seem all trial & error @ the moment.

Nice pict by the way.
