Conjunction of Moon and Jupiter

Clear skies tonight so anyone who wishes they'd seen the earth-grazing asteroid a few days ago you can make up for it by seeing the Moon and Jupiter very close together.

Unfortunately when I have zoom so both are in the viewfinder my camera won't focus properly, but I have a pics of both of them from about 20 minutes ago.

This isn't really off-topic as optics and photography have often featured in the pages of ME, and my question would be - any suggestions for getting digital cameras to work with telescopes?

Neil

I think it's called "digiscoping" try a search for it.

I thought about it for ocasional bird watching some time ago, but could not work out if my camera was suitable, so did not take it any further.

My camera was reluctant to work with the scope (itself a 30mm lens with an eypiece converter on it). I've had feeble results with binoculars and my compact digital.

I've heard of mounts that unite camera and scope - such a thing should be easy enough to make, if I knew how they work!

With the 'scope' I could see three of jupiter's moons just now.

Neil

Thanks for the heads up.

I have just had a great half hour outside in the freezing cold with our telescope.

It must be one of the clearest nights we have had for months.

I noticed that great sight here (Melbourne, Oz) too, amazing.

But your moon is upside down!!

Obviously not fit for purpose ?

See it here if you want.

Apologies for my last posting , I was part way through editing it and got called away.

Anyone looking to couple cameras and telescopes might find these useful.

An Internet search engine will reveal lots of other dealer sites, and useful information on the subject.

Hi Neil,

The adaptor you mentioned is a T-Ring or T-Adaptor and depends on the type of camera you have e.g. DSLR or Compact. I use a T-Ring with my DSLR for astrophotography and these connect the camera body directly to the telescope focusing tube (on an SCT scope) without the need for a camera lens.

The DSLR adaptors have a thread on one end to attach to a scope and the other is machined or threaded to fit to the camera's lens mount. This setup basically makes the scope a long focal length lens.

The compact camera adaptors are usually just a sleeve that threads onto a scope and allows the smaller diameter (non-detachable) compact lens to slide into the tube and is secured with some kind of locking screw or clamp, or just held in place with the camera mounted on a bracket of some form. I've not used this method but I'm sure there wil be many articles on line to show the setup and different ways to achieve focus.

Digiscoping is a term more used for birding or wildlife study.

I'm hoping to make an equatorial mount when I can get hold of a lathe and have a better understanding of machining and gears etc. The "seeing" here in Bristol was a little misty but I did notice the two objects last night.

Regards,
Ed.

Sid,

Many thanks for posting that link: as I imagine many others did, I went out with my binoculars several times on Friday night, only to see an unrelieved bank of dense cloud every time. I don't imagine, even if it had been clear, that I would have had as good a view of it as the one in that recording.

David,

Lot's of good stuff on the APOD site. One of the first places I visit each morning.

Thanks all.

V8 some useful ideas on those sites - interesting taht t-mount is still used for DSLRs - I have a 300mm standard and a 500mm mirror lens with t-mount, so presumably just an adaptor would give me som impressive lenses.

The two pics above were taken on my Nikon bridge camera with 4X digital zoom - effectively 2400mm so about 48x. Apparently Gillieo made do with 20x so I takes me 'at off to 'im, I does!

Neil

Yesterday morning the sun was very weak through the thin cloud not long after sunrise. I got this pic with the camera set at 80ASA, leaning on a car roof:

Very pleased with the sunspots - never caught those before. They match up with the live picture on NASA's SOHO site, but for some reason they have a slightly sharper picture than mine!

Neil

Nice one Neil. I've never dared point my camera at the sun like that for fear of burning out the ccd sensor. Here's the moon taken a couple of years ago when I was playing with my new bridge camera:

Nice balance with the sky, Russell. I would not are zoom in on the sun, but it was so weak you could look directly at it.

Neil

For you moon watchers out there I was sent this link to a full moon over Wellington NZ.

I was impressed by it anyway.

I used to try my hand at astrophotography a few years back before children etc. still have my telescope and camera stuff safely tucked away, but here's a few shots i was quite happy with.

All looks a bit nebulous to me

very impressive, Exactly what equipment do you have? A star-tracking equitorial mount would be a good project.
