Mars, the 26th March

[beamish]

Seeing was at times last night bordering on XLNT but generally good, transparency was good too.

First & last are RGB's , centre ® RGB taken between 21:43 and 22:25 U.T. 26/03/2012

All are shown at 100% scale no resizing at all, the Focal length was 11.559m so... f41.4

I was going to post my Saturn but it was a pile of do-do, too low!! I'll try again tonight but later when it's higher.

How on earth (or should that be Mars) did you get over 11 metres focal length? Astounding result anyway!

[beamish]

:)Ha , with one of these and patience of a saint

here's another version

Very good indeed, your best Mars I think. Good processing, not over sharpened and colour natural.

sorry to be dim, what is that and so how do you use that?

[Pete Presland]

nice images as well!

Ta

........it's a telescopic extender, it keeps the orientation of the camera the same, but TBH a set of T thread extensions would do it only mine weren't long enough

[Space Cowboy]

Super shots Karlo, glad you had good seeing!

[beamish]

Thanks Stuart

[Olorin]

very good result Karlo, send some of that good seeing my way as well :-)

[beamish]

cheers Olorin,

You can have it all, no more imaging for me ATM except may be Lunar, since my EFW control box has packed in

[AztecastroMcJ]

Excellent Karlo, lovely detail and processing

any attempt @f40 for me has been orange fuzzball so you done very well there aswell

[neil phillips]

very sharp Karlo, the uk is treating us at the moment isnt it

[beamish]

Thanks guys, yeah not too bad at all ATM - makes a pleasant change

Last night the seeing certainly wasn't going to stand F40 but it all became a bit irrelevant when the FW went Pete Tong! About to set up for my 1st C11 look at Venus and possibly shoot the Moon

[AztecastroMcJ]

hey Karlo was just having another gawp at these

and think u may have got focal length wrong ??

check sizes with mine and Peter's recent f/30 shots seem same

my f40 orange blob i have is way bigger than these at 100% scale

what u think ?

[beamish]

righto I'm off to check, hang on..................................

...........okay,

206x 5.6 ( Dp) =1153.6

12.97" /121 pixels= 0.107

1153.6/0.107= 10781mm

10781/279.4 (aperture)= 38.58

effective F ratio is F38.58 +/- a little cos I rushed it so no F40 is probably about right

[AztecastroMcJ]

check size with Peters ?

i was using ext + x3 Tal so mine should be f/29 - f/30

i have 1.25" visual back aswell

if i'm wrong i would like to know aswell bit worrying actually

what barlow were u using etc ?

[AztecastroMcJ]

Stuarts f/31 looks same size aswell

trying to convince myself here aswell as u

[beamish]

right I've just applied the same to your pics from here and came up with an efective F ratio of F45.8 for yours !!! 12.817metres

[AztecastroMcJ]

check Peter's lol

f/30 apparantly
