Spectra-L200 -first light

Recommended Posts

Hey guys,

I have just assembled the L200 and she is an absolute beauty!

I have a question, I have a 400D SLR and I'm interested in modifying it. Is it a good idea to use a modified DLSR for shooting the spectra thought the spectroscope? Removing the filter would allow Halpha to pass, thus increasing the signal.

Are there any side effects to using a modified camera for shooting spectra?

Side affects....Hmmm well I suppose there's the endless nights of processing all that additional data you'll collect:rolleyes:

No, a modified DSLR is a very good solution. I use a filter removed modded 1000D and it gives very good results.

See the image:

Top - Std canon 350D

Bottom - no filter modded 300D

No prizes for seeing the additional UV and the extended NIR.

What sort of grating is it that is in the L200? Is it a ruled reflection grating or is it a holographic grating? Also where could I pick up spare and additional higher resolution gratings?

I think Jack may have been refering to the spectral comparison shown in message #7
