Hubble palette and the DSLR

[swag72]

I keep seeing these hubble palette images and I find them utterly stunning. So, is it possible to get these images with a DSLR?

Its usualy done with a mono ccd and narrowband filters

[swag72]

I thought that was the case - But can it be done with a DSLR?

Not really - you need to use OIII & SII filters - the signal strength is usually very weak, a more sensitive mono ccd is required and even then we are talking about exposure times of 20/30 mins per sub.

You can do some lovely mono Ha images with a DSLR though.

What would you suggest would be the best filter to get mono Ha images with a DSLR? My DSLR is modded if that makes a difference.

Your mono pics are lovely John.

Oh, you're too kind

I used the Astronomik H Alpha Filter 12nm which is available in an EOS clip filter deign - it just drops in to the body of your camera where the lens goes. They are great.

I have a birthday coming and I was wondering about getting a couple of these filters. I like the clip design - Already have one - What filters would you suggest as there's loads there!!

[martin_h]

On that page - Astronomik H Alpha Filter 12nm and 6nm - EOS clip fitting

[swag72]

You wouldn't recommend any of the others Martin? Also, is it worth getting the 12nm and the 6nm?

No you only need 1 of those, John uses the 12nm so I guess that one works ok.

[swag72]

How about the OIII and SII? Wonder what kind of results you can get with them on a DSLR.

[martin_h]

Ruddy hard work I should imagine! On a mono CCD you are looking at sub times of 15 mins minimum, 20 -30 mins are the norm.

[swag72]

Mmm, sounds like hard work!! Maybe just a little too much for me right now!!!!

FWIW, I'd go for the more narrow pass band as it'll give you more HA and less noise plus it'll be less affected by light pollution and/or the Moon.

Seconded, having used the 12nm if I bought another I'd get the 6nm.

I wouldn't rule out narrowband imaging on the DSLR, you may want to look at this:

Maybe I might try it one day... certainly much cheaper then buying a decent mono ccd w/ narrowband filters. But who knows what the future holds, can you imagine that Unguided Narrowband Imaging..

How do you combine narrowband images with normal images? Or do you not bother and just take narrowband images? What kind of exposure subs are you looking at with narrowband?

[martin_h]

Normally you would just take narrowband BUT you can combine RGB with narrowband to get some interesting results. As for sub time - Ha- you might get something at 10 min subs but OIII and SII will need longer.
