Many thanks again to all for your comments on my Pelican attempt, i`m still playing with the data at the moment to see if i can get anymore out of it.

Uggs, amazing capture of Abell 2218.and all those fuzzy galaxies, quite an achievement, very nicely done indeed .Your Cigar is just excellent, first class for sure, again brillient .

James, as Tel says, those are really nice and detailed images of Saturn, be proud of them, we cannot control the seeing, thats in the lap of the weather gods, we can only make the best of our captures with processing to the best we can.Saturn of course, as with any solar system target, will be better captured when they reach a position much higher in altitude, sadly we have to wait for those years when they are riding high in our skies, but in the mean time keep plugging away,your doing just fine

best regards,

Tom.

Thanks very much for the feedback guys! I'm getting to the end of my image coffers (I try not to do more than one or two at a time to avoid flooding the forum). These next three images are re-processes of old data using new techniques that I have picked up in Pixinsight.

The first one is a re-process of data I gathered on M31 last summer. The image consists of 1h50m of 10 minute exposures captured with a QSI 583c through a Televue 127is guided on a Paramount ME. The differences in processing surround HDR management, accurate colour calibration, and local equalization.

This next one is a re-process of that Iris nebula (NGC 7023) data that never quite came out right last summer. Again, the biggest differences are around the colour calibration and HDR management. I think this one was about two hours of total data through the setup noted above. My only comment on the image is that it is dusty!

Cheers,
Dan

Wonerfully detailed images Dan ! I hope to achieve such results sometime in the future. They are truly inspirational. Please flood the forum.

Couldn't let this thread slip to page 3, so I've been looking around for something more obscure to try to image along the lines of emission nebulae just to see what the selective effect might be in overlaying Ha with Olll with my Atik 314L+, and found this one. Labelled NGC 7538, it sits in the constellation of Cepheus.

For a trial run, I chose to place it in a wide FOV although it would have benefited better from something a little narrower; it being only 9 arcmins. X 6 arcmins in size but interestingly enough, looking somewhat like the Crab nebula: the detail of which being there but couldn't under these conditions, be best presented.

Anyhow, for what it's worth, here's that initial result.

'Scope: 102mm (4") f/5.9 achromat.
Camera: Atik 314L+

Capture Software: Nebulosity 2.

Guide 'Scope: Celestron Nexstar 8i OTA @ f/6.3.
Guide Camera: Meade DSI Mk.1.

Guide Software: PHD

Mount: Skywatcher HEQ5 Pro.

Subs: 10 X 5 mins. in Ha. 10 X 5 mins. in Olll

3 X 5 mins. Darks. No Flats: No Bias.

Atik running at ca. -12 Celsius.

Processed in Nebulosity 2 / P/Shop CS2/ Registax 6.

Seeing conditions: fair to good.

Thank you for looking.

Best regards,
Tel

Excellent images, simply awesome by everyone. Some of the sharpest Saturn images that I have seen Hopskipson.

And Uggbits, your imaging capabilities are simply breathtaking to say the least. Each and every Messier you imaged is outstanding and the pictures leaps out.

Fine effort Tel considering your seeing conditions.

Great image Tel and one that most of us will not have seen before. And yes, it does resemble the "Crab".

Thanks for posting.

Regards. Peter.

Hello Gang...Simply great images taken by all of you...
Great to see that some of us have a better relationship with Mother Nature...Not me.

Keep them coming and keep on taking center stage...

Regards,
Pete

Many thanks folks, your comments are always much appreciated.

At the moment I'm trying to take advantage of a few clear nights, (they won't last), in order to see what a little tweaking to my mount might do to improve my images. I found, for instance, recently that my camera and filter wheel assembly was waggling about in my achromat's focuser draw tube quite significantly and that, with the weight of said camera and filter wheel, declination axis balance was also somewhat adrift !

Anyway, I set out last night to capture the Eastern Veil Nebula in both Ha and Olll and here's the result having combined the two images.

'Scope: 102mm (4") f/5.9 Achromat.
Camera: Atik 314L+

Guide 'scope: Nexstar 8i SCT at f/6.3
Guide camera: Meade DSI Mk.1.
Guide software: Stark Lab. PHD.

Mount: Skywatcher HEQ5 Pro GEM.

Subs: 10 x 5 mins. Ha. 10 x 5 mins. Olll.
Captured, stacked and processed in Nebulosity 2. Further processing in P/Shop CS2.

Seeing: Fair to good.

Thank you for looking.

Best regards,
Tel

Very nice Tel.

Glad you sorted out your waggling!

Here's my attempt from last night -

...I set out last night to capture the Western Veil Nebula in Ha, S2 and Olll and here's the result having combined the three images.

'Scope: Williams Optics ZS70 with 0.8 reducer/flattener
Camera: Atik something or other

Guided through 8x50 finder scope with DSI1.

Subs: 10 x 5 mins Ha. 10 x 10 mins Olll. 10 x 5 mins S2

Captured in Nebulosity 2.
Stacked in DSS.
Processed with fits liberator and P/Shop.

Seeing: Pretty much the same as just down the road in Wallingford.

Turning this into a jpg hasn't done it any favours...

Uggbits, great M31 and Iris nebula, superb imaging as usual, keep em coming!

Tel,great to see that Atik in action again, nice NGC 7538, and Eastern veil captures, , its clear to see that your Waggle problem has been solved just by comparing the stars in both images, the NGC 7538 stars look a little egg shaped, while the Eastern veil has perfect round stars.Nice job.

Andy, i have already sent you my comments via email, so again and suffice to say, great job on the Western veil nebula,love it .

best regards to all,

Tom.

Nice narrow band images! Good to see you got rid of your waggle, Tel (was it painful ?). Clear skies.

Superb "Witch's Broom", Andy ! It's nice when one uses narrow band imaging that, as opposed to "true" colour, (if it exists.... and we don't want to go down that road again, do we, guys?), one actually gets to choose how best to present one's image !

In my case, I've still yet to master the bicolour palette technique and, to that end, thank you for the information you sent me in that regard this morning.

I did, as I mentioned to you, also come across what is termed a "Kellner Ha stretch" feature contained in Nebulosity 2, which I have since applied, together with a degree of background sharpening, to my image above of the Eastern Veil nebula. Here's the modified result which I believe has "tightened up" the starry background and enhanced the wispiness of the nebula itself.

Thank you for looking.

Best regards,
Tel

Hi Tom, Hi James,

Many thanks for looking and your kind comments !

James; It was touch and go with The "Waggles" which, proved to be more frustrating than painful, but once diagnosed, thanks to the application of an adapter or two plus a little Teflon tape..........

Best regards,
Tel

Just be careful how you pull that tape off again Tel!!

I really like your second image - the first was nice but you've got it looking much sharper.

I've been messing about with mixing narrowband results in the channels in PS. I now have an Andy Warhol like Witches Broom!

"true" colour




What's that?

Hi Tel,
Your second "worked upon" image of the veil is a great improvement on the original, which in its self is a wonderful capture.
Not only is it much sharper and brighter, but the fainter parts of the nebula, instead of being lost as they are in the original, can be seen in the star field almost to the bottom edge of the image. Great work.

Regards. Peter.

Yes, Andy, it's amazing when one considers that the imaging precision of a 1000+ camera and an 85 filter wheel can and does apparently rely on a 4" strip of plumber's tape to ensure the two a) don't produce a loose fit or worse, b) part company !

Best regards,
tel

Many thanks, Peter ! It's really nice to get a good image once in a while amid all those others which don't come up to snuff for one reason or another.

Still, I suppose it's like everything else one strives to do: you know, three steps forward; two steps back ! .

Perhaps though, that's what maintains the interest. A little like Golf perhaps ?

Best regards,
Tel

Very images, Tel.

As for golf, not a fan, except for driving around in the carts. If you get one with a full charge, you can get enough speed to jump them on small hills.
