Very nice Job Roger. You're making me seriously think about modding one of my SPC900's :)

Hello Rogerthedodger,

Im amazed at these pics. You have a similar setup to me and ive been trying to capture these with a Canon cam, these are excellent! I live close to you(dudley)so i can no longer blame light pollution(in the sticks aswell), one question though did you modify webcam as far as amp-off mod?

Thanks

Rich T

Hi Rich, yes I have the amp-off mod which does help. Also, I quite often stack these with registax with just a single dark before processing. One day I'll get around to getting an LP filter which should improve things.

Thanks roger,

I have to be honest the amp off is above me, so just installed a small fan. Haven't really tried it yet as need lead to connect to pc, a fifty foot one! Do you have a link to the instructions you followed? Also to get the m57 that close up presumably you had a lens between, what size was it? Thanks again bud, great images.

PS Have you considered Baader Sky Glow filter, seems to make sky very dark, not sure what the result would be on nebula though as cant get canon to focus to try.

The main directions are here http://www.boltonastro.org.uk/Members_Area/Projects/spc880conversion.pdf and this post from Lee shows the wiring more clearly http://stargazerslounge.com/1756146-post109.html in fact, it may be worth looking through that entire thread as there are a lot of hints/discussions in there on doing this mod.

The DSO pics are with no extra magnification, just the webcam on the 'scope - don't forget the webcam has a much smaller FOV than your canon.

Looks like the core of Andromeda, I had the same problem with my DSLR. I didnt realize how bright M31 is and I totally blew out the core with a long, high ISO exposure.

Yes it is, I just spotted the same stars in Davy999's pic in another thread. I still pleased with it though :)

I know I am late to the party, but I thinks these photographs are fabulous! I have the same cam with the same mod - shame I don't have an EQ mount!

Thanks Sam. It'd be interesting if you could try 20 sec exposures and see what comes out, DSS should eliminate the rotation in stacking, but it will narrow the FOV.

It's worth a try! :) The strange thing is, it is clearing up tonight, even though the forecast was for thick, grey cloud...

Having just ordered a webcam, I can't wait to start having a play at trying to get some images. I've a feeling a steep learning curve and expense are coming up! :)

That's impressive! Any chance you could give more info on what you did?

I think these are an inspiration for many to consider some imaging :(

39 x 74s guided, 4 darks with an LX modded SPC900 - while I was trying to get guiding to work reliably I thought I'd try this as a target, nice that it fits in the FOV of the webcam :)
