M51 with C14 test image

Hi all,

I had a chance to get out imaging for first time in a long time. So I got to test the AP1200 mount properly and here is the result of 60 x 2min exposures unguided with C14@3910mm focal length binning was 2x2 camera was Atik 4meg @-20deg.
This was my first time imaging at such a high focal length getting the focus right was a challenge the image was processed in images plus and Photoshop CS3 Darks was 30 x 2mins flats was 35000adu

@-20deg?

Is that 20C below ambient or is that -20C?
Sorry to be pedantic.

None the less, I like the capture - also its a wonderful target.

Hi Mark,

No Problem it's below ambient thanks for the feed back

Carl.

Thats some serious tracking there Carl,
Very nice!

Excellent image there Carl with finer structures now visible in M51 and NGC5195 and well framed. Like Mark I have a technical question regarding if you captured the images unfiltered or filtered.
I would also recommend that you get your hands on an Optec TCF unit for taking care of focusing during imaging runs through the night especially when using longer focal lengths. I am sure your going to have lots of fun with the AP1200 and I am looking forward to additional images.

Hi Mike,

The image was taking with no filters I have a Crayford Moonlite auto focuser I think Gary has it I must locate it.

Thanks for the comments.

Carl.
