Same advice than wildlifephotog.

My 10 years old son is having a lot of fun with his 200mm dobson (Skyquest Intelliquest).
This model's price was about 600 €, and includes a sky pointing electronic assistance device.

Basically, the 2 axis (altitude and azimut) have coders with a 0.1 angular resolution. you need to align the telescope with two chosen stars and the computer will then know its exact position and orientation.
You can then select an object you want to see (planetary or deep space, like a nebula or galaxy) and the coders will display angular offset. Set the two values to zero by moving manually the two axis, and look in an eyepiece with a large angle of vision. That's it.

One more advice: the quality of your viewing experience will directly depend on the quality of your eyepieces. In my opinion, that's where the spending effort should be.

Hi there,

What you need to consider:
- Optical formula (refractor, reflector)
- Mount (german equatorial mount on tripod, Altitude/Azimutal arm, dobsonian)
- Motorized or not

For astrophotography, you basically need an equatorial mount (i.e. that's aligned with Polaris), motorized to compensate earth's rotation.

I would suggest to move gradually into the hobby. First of all, grab a good paper sky map (or download one of the many freewares available on internet), and get a good pair of binoculars.
It's lightweight, instantly available (no need to calibrate or install anything) and surprisingly rewarding. You can catch some deep spaces objects and see the biggest planets of the solar system.

Then, if you definitively catch the virus, but are on a budget, I would recommend a reflector on a dobson mount. You get a larger diameter for the dollar, and that's finally what matters.

The larger the diameter of the tube, the more light you can receive on the back mirror, thus giving you the possibility of viewing very faint stellar objects.

Magnification is really a secondary aspect. It could help catching details in planetary observations, but at the cost of the quantity of light you can catch.

Clear skies...

Stu,

It may be redudant saying this, but what you've done for this little girl is just awesome. I'm sure that for the rest of her life, when she'll hear a shutter click, she'll remember you!

I've started to loan my digital cams to my kids as soon as they had enough motricity to stand still for a second or so (that's about 4-5 years old).
Since then, they produced amazing shots, much better (in my opinion) that what I could acheive with my fairly technical approach to photography. My older one (he's just turned 10) is producing still-images movies with my old Oly p&s and lego bricks.

Natural, they say... ;)

Pretty much anything will do, except commercial R&B crap.

Lots of stuff from the nineties (Pixies, Ride, Boo radleys, High llamas, The Cult), then some electronic music every now and then(french band Air, mostly).

Classical music (that's what I was originally educated to), and Blues from the Delta.

All in all, I believe life's worthless without music. With photography, it's the most powerful emotion vector to me.

I'll get the pics done this week-end. That's gonna be a good assignment for my recently acquired K200D !

As for water resistance, I can get to my local Decathlon dealer and ask for more detailed specs.

I must admit that I've never used it under heavy shower, but never had an issue with humidity or "regular" rain (whatever regular means here in center of France;).

And it stands up to the task.

Very easy to deploy and secure, fairly good impermeability. You need a couple of minutes to get the trick to pack it back, but only if you have two left hands (which is my case, btw).

I own a 3'' version, room for 2 and a good deal of space left.

If you need some more info, I can get it out in the backyard and shoot a couple of pics :)

Sure looks like a sweet deal... in the US at least!

Found on Amazon.com : D-BG3 for $40.88

Found on Amazon.fr : D-BG3 for 100.64 (a whopping $135 !)

The european version must include platinum connection pin or something to justify 3 times the US price!!!

Go figure...

Hi there,

A few words to introduce myself here...

I'm living near Blois, in the Loire Valley, which is a pretty nice playfield for landscape, nature and architecture shots.

I've recently got into digital photography a little more seriously with the acquisition of a K200D (Olympus p&s before that). I'm still in the steepy part of the learning curve, but I've already found a great source of information by browsing the forum.

Thanks in advance for your help and support !
