Title: Getting started - Choosing software and a webcam
Post by: Delphine on Oct 15, 2007, 16:56:41
Thanks for continuing this discussion publically - I appreciate it.

I have a couple of really basic questions to ask I'm afraid.

1.  I would like to practice with Registax and the K3ccdtools v 1 and download them now before I buy a webcam.  Is this physically possible or do they need some kind of tie in with the webcam? 

2.  I have searched the net for webcams and found a Philips SPC900NC from Amazon.  Not sure if it is a Toucam but it has a CCD chip in it.  would this be OK? - other amateur astronomers seem to rate it.

3.  Am I correct in thinking that the webcam doesn't need to be modified if you are just going to do the moon and planets?  -  I don't know what modification is required but suspect I don't need to know!!

Cheers
Delphine

I have just heard from Miriam that the Philips SPC900NC is the one that she has so I am going to get one of those.

Hi Delphine - Not basic questions at all...

You can certainly practice with Registax if you have an avi file - K3 you will need to have a webcam connected to practice capturing (unless you just want to use it to process).

The SPC900NC is a great starter camera - The CCD chip is great - it is more sensitive than a CMOS one.. it does not need to be modified for the moon or planets - you will need to get an Infra Red blocking filter & also a nose piece so you can connect the camera to your telescope - you can see examples here although shop around (you may get cheaper).

It's basically the same webcam as I started with.

Cheers,  John

(Just split this thread out of the monster "Digital Photography" one, as it's a new question or three.)

if I remember (and that's a big if) I'll write some of my old planetary avis to a cdrom if you want to have a practice. There's nothing special about them though...

I'm reading this one too as Miriam and Delphine are a step ahead of me and taking notes.

Hi John

Many thanks John for your advice & information.  I clicked onto the website link you gave me so I now know what the filter looks like and where to buy it!  Thanks also for the reassurance that I will be buying the correct webcam.  

I am glad that I can practice with Registax without actually having the camera as I am not sure when I would be able to produce my own images to process.

Cheers
Delphine

Hi Ian

Many thanks for your offer to give me some of your planetary AVI files on a CD [if you remember!].  I really appreciate it.

Cheers
Delphine

I have just ordered the Philips SPC900NC from Amazon and the IR-UV filter and adaptor from Telescope House.  Now I am eagerly awaiting delivery :D.  Thanks for your advice everyone.

Woohoo !! I can't wait for your fantastic images of the moon, Jupiter, Saturn and Mars. We have a plethora of new imagers recently, this is great. One of the things I hoped would come out of Deep Sky Camp and the Imaging Sessions would be to encourage more people to give astrophotography a go so i'm happy :)

Thanks for your encouragement Mike.  Not sure if the word 'fantastic' is the right one but I will do my best :D

Getting an image through a telescope isn't so hard, but getting it all right all the same time takes a bit of work. So based on that *any* image you make starts off at fantastic and will with time and practice head towards eye-popping.

That's why it's sufficiently rewarding to spend a small fortune on kit to sit out, on your tod, in the cold and dark, all night to get one image.

Hooray!!  Today I have loaded the webcam onto my laptop and downloaded K3CCD V1 and Registax.  All seems to be OK.  I have been playing around with the Jupiter AVI that Ian gave me in K3CCD.  Now I have got to figure out how to capture images.  I tested the webcam but didn't know how to switch it off so I have video of myself looking very puzzled!!!  Lots to learn but fingers crossed everything seem to be working at the moment :D

Ah, yes, I remember I had to give you some additional information about that avi that I gave to you. It was the output from a modified webcam that gives a less processed image (webcams normally do some processing such as sharpening and colour balance on the fly). If you notice the colours looking a little strange that'll be why.

That said, it'll still stack and so on. We can go on to talk about some of the software mods after you've got going with it as it is...

Many thanks Ian.  However as you suggest I will practice with the software as it is at the moment - I don't want to confuse myself too much!!

Well done Delphine, we seem to be at roughly the same point, except you've done some reading up on the subject and I haven't had time to do that as yet, it's difficult to fit everything in when you work full time.  Perhaps we should keep in touch with each other and compare notes.

Ian, did you lend Delphine a video to play around with on Registax and if so, could I perhaps borrow it too when Delphione has finished with it.  I haven't yet downloaded registax, but I probably will.

that's no problem Delphine, if you get a final image, post it and we see how you're getting on. If it's better than mine you can the teach me what you did.

It'll work with registax as well Carole, so feel free...

Hi Ian

I have been using your saturn avi to play around with registax and KCCD but am not sure if I have sussed it correctly.  You have told me a couple of times that there is a  website which explains [in simple terms] how to use the imaging software.  Unfortunately I can't find it on the forums - please can you point me in the right direction. 

Many thanks.
Delphine

This is the site. He's got loads of tutorials about all sorts of stuff. He's a dutch guy called Jan Timmermans who is something of a key player in the QCUIAG group.
