It was a pretty miserable saturday- murky, cold & raining. I had that sinking no astronomy feeling- you know the one I mean.

 

At 2.00AM Sunday morning I happened to glance out of the window and the Sky was really clear- I mean unusually transparent for my region and quite dark.

 

I knew that the local group galaxies were high- M81 & M82 were nearly on the Meridian. I swung the C14 into action.

 

I have always wanted to capture M81- but either it was never well placed or the weather was not co-operating.

 

The image I managed to capture came out good for my conditions-  I'm probably Bortle 8 at best.

 

I took 12 RGB 3 minute subs in each channel and 22 3 minute L subs. All at 2x2 bin on the ASI6200 with Baader LRGB filters. C14 Edge at F11.

 

A larger image is posted here https://www.astrobin.com/380v2s/

 

It is a shame that I can't position my camera sensor to suit as it slightly cropped the galaxy however when rotated it kind of gives the effect of falling in which I really like.

 

As always let me know what you think of the image

 

Best wishes

Mark

 

........stay safe in these troubled times.

Nice image. Tight core too. I’m almost more impressed you can take 3 min subs in bottle 8. In my neck of the woods, that’s a white washed out image unless I got darn near narrowband

Whilst I am in Bortle 8 my garden has high sided walls & my telescope is in a corner which helps a bit. There are very wide changes in Sky brightness. I get the darkest sky after a rain storm which happened last night.

Always impressed what people lost from such light polluted skies. Now the next thing to overcome will be the massive influx of satellites being put into orbit!

Very nice!

One bonus of your camera orientation is that you got UGC5336 showing very nicely.  Well done!

Thank you all for the kind comments. I face the challenges with a smile- the hard work does eventually pay off.

I think its a shot like this that keeps most of us going in this hobby... So many challenges, but when you have those nights where you get great data and a shot you're proud of is the result it makes all the headache worth it. It rejuvenates you and keeps you going and forgetting the nights it didn't go so well, or not at all...

 

Excellent work!

 

Regards,

Skyhunter1

I have removed several posts from this thread which devolved into bickering and mutual ad-hominem attacks. The posts didn't have to take that direction--it all started rather innocently and then one slight led to another and so on.

 

I would like to remind everyone a few things, all parts of the "play nice" spirit:

 

1) When someone asks for criticism, please try to be gentle *even if the poster made no such requirement*. Remember that standards differ. 

2) When someone makes an honest if apparently over-critical comment, it's sometimes best to ignore it. It may well have been made in good faith. It may also be wrong. It's only an opinion. 

3) If someone steps outside the bounds of civility, do NOT step out of bounds yourself. Post a moderator alert, and happily browse other threads pending resolution. 

4) No poster "owns" a thread on CN. If you post, you accept that any member in good standing may reply, as long as it's done in the "play nice" spirit and stays within the TOS. 

 

Thank you, and let's go back to admiring/discussing the image posted in a pleasant way.

I absolutely love these images of galaxies up close, of which we normally see wider shots of. Really changes the perspective in a fresh way...great work :)

The C14 at 4 metres focal length gives this perspective out of the box- however you then enter a world of pain with guiding requirements and all the equipment to match. I would estimate that I must have spent £50K on the equipment I have and too be honest the spending can go on infinetly because there is always some desireable new gadget.

Very nice 👍
Looks like a nice future target for my C9.25.
You are tempting me to spend more money for a dedicated monochrome sensor and filters etc.

Very nice.  Looks 3D to me.  I see that top spiral arm rising up out of the plane of the galaxy and extending upwards.

I have that impression as well- it felt I was being grabbed by the center black hole and was being pulled in

Thanks Michael- its a truly wonderful Galaxy- I'm so glad it is part of local group and being available all year you can just keep on practicing your skills all year round. I need to work on the stars but currently I'm more than happy.
