Ha is quite good isn't it....

Hmmm OK this isn’t too bad. Currently having a play with new Ha filter. Attached to ATIK 16IC looking at Crescent Neb, single 5 min sub – only curves processed – I’ll post final image when it’s done. Only tried Ha cos not done any imaging for ages and Moon is up again tonight.

That's really good going for one 5 min sub!

It's great the way it cuts through everything even when the moon is right up there

That single sub is a mighty impressive argument for buying an Ha filter. What bandwidth is the one you are using?

[msinclairinork]

yup, your on to a winner here!

Looking forward to the finished product!

Keep us posted

It’s an Astronomik 12nm. Think it was about £100

Got lots more subs – will post result when stacked and processed.

Off camping for the weekend now….Hope the weather holds up.

Outstanding for 5 mins. If you can get the guiding to behave Ha thrives on long subs. I was bashing away at the Heart on 15 mins a throw the other night.

Ha is THE filter, as you imply. It pulls out a glory of structural detail in nebulae and gives incredible resolution. Also you don't need a highly corrected apo to get a result, a basic semi apo is fine.

Cor 5 minutes, thats excellent nice and clean with plenty of detail, wish my subs were like that:D

Ha gets us out imaging when theres a full moon so its definitely good

I just bought a 12nm DSLR filter a few days ago, really REALLY looking forward to using it now!

Does anyone know if the 35nm one advertised by FLO is any good?

Ask them. They are honest guys.

Ok – final image attached.

ATIK 16IC with Astronomik 12nm Ha filter on a WO Megrez 72

2.5 hours in 5 min & 7 min subs over two days (when the moon was up)

Guided with PHD & EQMOD on an EQ6 Pro

Dark-framed, aligned & stacked in Nebulosity, curves, levels & tweaked in Photoshop.

I was lazy and didn’t re-frame correctly when it passed over the meridian; as such I had to crop a lot of the edges from the image ….

Now I know Ha works well I will have to setup a list of “moon night” targets.

Stunning, that is just beautiful. I've just been trying out the same filter I bought recently, and it seems to do a great job in the Moonlit nights.

Wow that is fantastic!!! Ha looks very interesting indeed. I just checked out the cost for the EOS CLS Clip version £150.00. Has anyone tried doing any Ha using a 1000d??

Well done Mick. I am just about to blow this months expenses..lol
