Many thanks, Ben, for your kind appreciation.

Golf fan ? Nor me. Perhaps because over here, golf buggies are far more of a rarity and golf courses are "long things" !

No, nowadays, I tend more and more to heed the one time words of Winston Churchill :

"Why stand up when you can sit down, and why sit down when you can lie down" !

And, the older I get, the more ....... !

Best regards,
Tel

With a tremendous amount of help from Andy, (Mushroom Bill) ; with regard to frame alignment in P/Shop, I've at last been able to make my first steps into the use of the "Hubble Palette"; (the artificial colouring of celestial objects).

Taking therefore the monochrome subs produced from my attempts at Ha and Olll imaging of the Eastern Veil nebula, (above), here's the result.

Thank you for looking.

Best regards,
Tel

It is coming along nicely Tel. Now for the S2 filter?

Iím always grateful for the help you gave me when I started out so glad to assist when I can. Clearly, I don't know that much as I made the Veil nebula blue and green!!

Talking of which hereís another from my Veil Nebula series. Same details as before, just switched around the RGB channels.

Many thanks, Andy !

As to "paprika", James, I don't know, you may well be right in your interpretation but remembering that this colouration within this narrowband and thus monochrome imaging discipline is "introduced" and thus as such can be varied at a touch of the "Hue" and "Saturation" sliders, I think they nevertheless, make for attractive (even fun, if you like), images. After all, it's a technique widely used by the "Hubble" and what beautiful images it produces.

I was introduced to it by Nik Syzmanek; the author of "Infinity Rising" and article writer for the UK's "Astronomy Now" monthly magazine, who, on the topic, quotes the result of such "paletting" as follows:

"I'll stress here that these kinds of colour shifts are purely to the taste of the imager. Narrowband images are more akin to false colour images, unlike the careful processing we apply to broadband galaxy images, so we can allow ourselves a measure of artistic licence here".

(Perhaps we go too far) !

Keep the comments coming !

Best regards,
Tel

Thanks, Ben, your comments much appreciated. It certainly adds a new, (perhaps novel?) dimension to narrowband imaging !

What will you lads come up with next. Amazing.

As I said above, I just love the colours, true or not.

Please keep playing.

Regards. Peter.

Still experimenting with bi-colour processing a-la- Hubble palette.

It's great fun !

Many thanks for looking.

Very nice Wizard, Tel . Looks like your getting the hang of this. I looks a lot "smoother" than the Veil.

Many thanks, James ! Much appreciated ! It's good to practice the art. The problem is though, getting the images in the first place !

Summer on Summer and Winter on Winter weather patterns over here these days, are guaranteed to give us about 80% cloud cover day and night throughout almost any year, and with very short runs: probably only ca. three nights maximum at any one time of clear skies !

Bah !

Best regards,
Tel

Like this re-pro better Tel, you certainly seem to be getting the hang of using the Hubble palette for colour .

I wont mention the weather, too damn depressing

regards,

Tom.

Always wanted to ask you this ( and other members living in the area as well ), if you ever get to see or image the Milky Way.

I think I have to revisit these and try to reprocess them.

What lens are you using for Milky Way shots?

The 14-24mm F2.8 I want to buy for the wife's camera will set me back around $700.

I swear, that thing is exactly like a telescope... Only as good as the lens/EP you buy. LOL.

Hi James,

A splendid shot of the Milky Way ! (Particularly from Queens NY) !

Seriously though, many congratulations on a fine image !

Couldn't however resist the "tweak" ! (All good practice) !

Best regards,
Tel

For the first time in three weeks the skies were reasonable over southern England: not great, due to some high atmospheric haziness, but nevertheless, at least something with which to work.

This then is the Crescent Nebula, (NGC 6888), in Cygnus, captured last night/early morning in Ha.

Capture 'scope: Phenix 102mm, f/5.9 achromat with Baader semi- apo filter.

Camera: Atik 314L CCD monochrome.

Capture software: Stark Lab.Nebulosity 2.

Guide 'scope: Nexstar 8i OTA at f/6.3.

Guide camera: Meade DSI.

Guide software: Stark Lab. PHD.

10 subs. at 5 minutes per sub. No flats, darks or bias. Camera temperature ca. -12C.

The capture was equally made using an Olll filter which will serve to present a bi-colour palette image when I get around to assessing its quality.

Many thanks for looking.

Best regards,
Tel
