Not bad, I think you can see both of the satellite galaxies as well!

Zatnikitelman, that only took a 500mm (Telephoto?) lense to get such a close-up of the moon?

The moon is quite big

Also, the picture seems slightly out of focus to me.

Yep, it's a 500mm lens, but I'm not sure if it qualifies as "telephoto." I'll try again tonight if it's clear to see if I can't help the focusing. I've got the focus set to infinity when I take these pics (you should see the rejects! ) and I'll check to see if it's somehow sliding down or coming out of focus when the shutter goes off (I use timer mode so I can dampen the vibrations before it actually goes off). Tonight might also be less windy which could have caused some of the blurring.

With Nikon's D80 CCD, it's about 3.2 degrees field of view for 500 mm lens, so by adding to it uncropped picture size of 3872 x 2592 pixels, it's pretty possible to get Moon that big, after cropping almost half of the image.

I should try and find M33 through my telescope. I can see M32 quite easily, so am I likely to be able to find M33?

My introduction into Astrophotography:

I've tried pointing my digital cam through the eyepiece of my 6 cm refractor, but no success, so this week I tried taking many images, just using optical zoom on my cam.

Here are the results:

Part of the constellation Orion:



The three bright starts top right are the Orion's belt. To my surprise, a bit of the Great nebula in Orion can be seen.
103 x 4 second exposure, ISO200, 4x optical zoom. A mistake I made was using F3.2, instead of F2.8. I didn't notice the cam change the setting until I was done shooting. Next time I'll use F2.8, which will give about 1.5 times brightness.


Pleiades:


Pleiades is a nebula / young cluster of stars. You can see it in the sky even from a light polluted city. A person with normal vission should be able to resolve 7 to 8 stars in a light polluted area.

It's located "towards the west" of constellation Orion, with a bunch of relativelly bright stars very close together.

This image was compiled from 76 images of 1 second exposure, 12x optical zoom, ISO200, F3.2.



These are my first two stacked images, so any imput is welcome.

The main problem I've had shooting with the cam on a tripod alone is that if I used zoom, I would have to restrict my exposure time, to prevent the stars from being smudgy. A 12x zoom will only allow a max of 1 second exposures. A 4x zoom will only allow around 4 second exposures...

Also, I'm restricted to using low ISO. I tried using ISO1000, but then DeepSkyStacker mistook the noise in the image as stars and the end result was horrible.

I know DeepSkyStacker wasn't really designed with digital cameras pointed at the sky in mind, so if anyone has any experience to share, I'd be thankful.

Since you are a crafty person, I suspect you will be able to build an Equatorial Mount very easily. There are some good tutorials for homemade ones to be found on the net.
I am planning to build one myself but never get around to it But I might get my hands on a 300mm lens soon. That will certainly provide me with enough incentive to finally build one.

Build one, huh? That's a pretty good idea!

I'll have a look for some online tutorials. I have some spare wood and I should have all the tools I'll need. If I do build one, I'll be sure to make a thread

Thanks
