IC 446 to NGC 2264 - OSC widefield

[old_eyes]

A widefield OSC image of an attractive part of the sky from IC 446 to the Christmas Tree Cluster (NGC 2264) in Monoceros. Emission, reflection and dark nebulae.

A total of 2 hrs exposure on Pier 5 @Roboscopes in Spain - Tak Epsilon 180, ASI 2400 MC Pro, unguided Paramount MX.

Very nice. Have yet to process my data of the same region. I really like IC2169

Wow.  Absolutely stunning!

Its beautiful!

Yes, the whole reflection complex of IC 2169, NGC 2245, NGC 2247 and IC 446 is very nice, and there is a lot more detail in those nebulae than I have brought out in this image. If I can find a way I will try and get a closer view of these objects.

Do you have OSC or LRGB data? I was surprised how good the OSC came out.

OSC and ha, getting some luminance and more OSC tonight.

Very nice indeed, trying to build up exposure time doing this target group myself with 300mm fl and aps-c 2600 OSC, similar fov.

At 300mm FL I assume you are using a camera lens. What F ratio are you operating at? The Epsilon 180 is F2.8, and therefore pretty fast (near RASA fast). As I noted, I only used 2 hours exposure to get that image, so depending on your F-number and skies, you should not have to wait too long for a nice image.

I would be interested to see what Ha adds to the image!

No, it's a 60mm f/5 quintuplet and already getting all the colour through after 1.5 hrs.  Not like your 180ed or my 130D but thankfully it's a fairly bright target and comes through nicely on the scope/camera combination with similar fov to yours. Houses cut it off for me 1 hr after meridian so it will get 2 hrs or so before moving onto the main targets of the next few nights. It's a nice target group though

F5 is still pretty fast. Around 3x longer exposure for the same number of photons, so a few nights at 2 hours will give you a nice SNR.
