NGC7000. First go at Narrowband, DSLR

[PaulB]

On Friday, here in Macclesfield. The cloud gods took the night off. I am sorry if they invaded some body else's skies on Friday evening.

I used the time to image NGC 7000 using my Canon 1000d (modified) with a new narrow band filter I have recently bought. This is a Astronomik 6nm Ha EOS clip, that I bought from Modern Astronomy last month, but hadn't used yet.

I have the camera attached to my William Optics ZS66sd which has a WO Flattener 6 attached. This reduces the focal length from 388mm to 310mm, with a slightly fast F ratio (4.8)

Guiding is via PHD2 with a QHY5II and 50mm Pentacon lens, and for DSLR capture I use APT.

5x900 seconds with 2x900 second dark frames added. These were stacked in DSS and processed in StarTools, and PS.

Because the filter is 6nm. It is very dark. So you need more exposures than I used here. This is a work in progress.

Great image. Do you plan to add Ha to rgb taken without filter?

Great start and welcome to narrowband DSO imaging

[PaulB]

Thank you.

Wim.

At the moment. I want to stay with Mono, until I am more familiar, with this type of imaging. 

Gina.

Thank you.

I am used to CCD narrowband. But- Not DSLR. You certainly miss the sensitivity of a cooled CCD for narrow band photography

Nice image.

[PaulB]

Thank you.

Looks like a great start to your narrowband imaging
