Melotte-15 in Ha (IC1805)

[swag72]

I want to do a narrowband image of this, but the moon and a couple of moves of the CCD have put paid to it with this data anyway. So I have settled on an Ha image of this region for the moment anyway. I continue to really enjoy the little scope I have and know that I have made the right decision to abandon the 120ED and look towards more widefield with another Atik (Once I've decided which one!)

Using the 5 hours of Ha data from last night, I hope to add OIII and SII to this for another NB project.

M: HEQ5

T: Pentax 75SDHF

C: Atik 314L+ Baader 7nm Ha filter and Trutek manual filter wheel

31 x 2100s of exposures

Very nice smooth start you have made there Sara. Plenty of detail showing

[Shibby]

Ah, so that's how it's supposed to look!

Great job, you have just managed to frame all the most interesting bits.

[swag72]

Thanks both for looking. I think that the widefield on this one Lewis is more interesting, but unfortunately at the moment I can only go in close!

[Jessun]

Really nice! Phenomenal exposure times for the HEQ5 trooper!

[Martin-Devon]

Wow - 35 minute subs - that's really special - very nice round stars as well so you must have that Pempro working nicely. Really nice deep & detailed image, look forward to seeing the rest of the composition following other filters.

[swag72]

Thanks both - Martin only 1200s subs, got the numbers round the wrong way!!!

Having a go at a mosaic for the first time ever on this target while I waut for that dastardly moon to leave the area!!

[prokyon]

Great Halpha result! Good decission to take the little Pentax. Could become a stunning hubble palette.

[Gina]

Very nice indeed

[swag72]

Thanks Prokyon and Gina - Managed to collect a couple of panes last night for a mosaic, so will settle on that at the moment!

[farunj]

Wow!! That's superb!! Awesome!!

[Tim]

Very nice and smooth Sara. So is that 18 hours worth then?

Cheers

Tim

Imaging excellence as usual.

Your trade mark is becoming, "Smoothly sharp"

Could that be telling you what CCD to go for in the future ? Or do you want a wider field ?

Dave.

Thanks Tim and Dave. This is 10 hours of subs, only 1200s per sub, not 2100 as per my typo!!

Looking at widefield Dave, so either a 460 Atik or a 4000. Just need some comparison type data between the two instead of figures!!

[Tim]

I think the 460 uses the same chip style as the 428ex.

If you would like to see some results from mine, just shout. I have to say, I am extremely pleased with the 428ex. Using at the moment with a Borg77 at 1x1, but it is also very useful at 2x2 with my C11, even working at F10.

I was used to using the SX H9 which was great, but have to say I like the Atik 428 even more

[swag72]

Cheers Tim. I am very torn between the sensitivity of the 460 and the fov of the 4000 - I can not decide. Well, I do for one day, read something else then change my mind again.

Procrastination and too much information on the net will be the death of me!!

masterpiece!!!,

how did you manage 2100sec single exposure?!

Only 1200s exposures - A typo with no edit facility!!
