moon with 90mm lens on M8

I am obsessed with the moon and getting it with my M8. It is not easy. This is the best so far.

Caryl

it is not easy because as Stuart pointed out, you are using the wrong tool for this job

the 90 just isn't long enough to give you the detail you want

as you know I find the Viso/M8 combination excellent for such photographs & that would open up a world of long lenses that really aren't all that comparatively expensive

that said, you may find that setting the focus slightly beyond or below infinity will yield a sharper image as this moon looks a bit soft ...bracketing your focus may help

Hi Caryl,

 

Great shot, especially with a 90mm. People often don't realize just how difficult it is to shoot the moon. When you see those pictures with the moon filling in the whole frame (like Hollywood does it - ET comes to mind), you have to start using things like 800mm lenses. In addition to this, if you expose for more than just a few seconds, you start to pick up the movement of the moon.

 

Good luck. Thanks for sharing.

Thank you Andreas. I have an entire folder of moons at

moon_shots Photo Gallery by Caryl Ritter at pbase.com

Most of them are shot with a 400mm lens on my Nikon. I would like to get the same quality with the Leica but I am not about to spend thousands on more equipment. I have even explored attaching a monoscope to a camera. It is becoming an obsession~ LOL

Don't forget that the moon is in full sun, and the sunny 16 rule applies.

 

In order to get a decent sized moon in the frame you definitely need to go longer. My 560 Telyt, on the DMR (= 756mm) just about gets to full frame.

 

There's an example on here, somewhere.

If you are using an ISO of 100 (say), on a typical sunny day (intemperate lattitudes), the f-stop you require will be 16, with a shutter speed of 1/125

 

If you are using ISO 400, the shutter speed is 500th.

 

Make the shutter speed as near to the ISO as possible, with an f-stop of 16, and in the sunshine, the exposure will be there or there abouts.

 

In the tropics, or at the poles, things will be different of course, but it was (is) a very handy rule for reversal films especially.

 

So, for a moon shot, 125th at f16 at ISO 100 is about right, because the moon is in full sunshine.

 

Here is my attempt from earlier in the year

Will the old telyts fit on my M8? I do not want to mess it up.

Caryl

 

Caryl, the old telyts are perfect on M8: simply, you have to get a Visoflex III (or even the II, limited to vertical finder, that btw is almost easier to use than the prism when you put the gear on a tripod), and then you must be sure to find the lens with the Visoflex attachment (they were available also for Leica SLR... the attachment is interchangeable, but obviously is better to find at once the right one).

 

Inspecting the glass conditions is easy, they are made of a simple coupled pair of glasses : this makes them prone to spherical abherration, but there are two simple rules about:

 

1) The M8 is "cropped" vs, the 24x36 area : spherical abherration is "naturally" lower.

2) The more you can close, the better the image : on a tripod, with static subject, you can close even to f32... the coupled pair is so large that diffraction induced by diaphragm is anyway not significant.

 

And repeat, you can find them at good prices : in these days, Westlicht auction in Wien offered a 400, mint and complete, at the base price of 200 Euros, and a mint complete set with both the 400 and 560 heads at the base price of 400 Euros (you can use both heads on the same focusing assembly).

And LOOK at the fantastic Artichoke's MOON quoted in this thread !!! Taken with the 560....

Thank you for all that info but I think i shalljust use my Nikon for the moon. Here is my best.

Caryl

 

Ouch ! That's superb ! I thought you had no long teles... being not so... well.. let's admit that the Telyt / Visoflex combo is just for Leicaphiles... I used SLR just a little, years and ears ago (bulky Contarex...) and there is no doubt that for strong tele they are the right choice...
