Taken 231107 17.35, with SX thru ED80, guided with PHD via EOZS66. L= 9x300secs Ha = 6x300secs/CLS filter.
This wa going to be RGB but full Moon was about to appear from behind a tree, so I did not have time.

I had to delete 3 of the L due to star trailing.

No tree, and the Moon'd have got you sooner. Guess they're useful for sometimes. ;)

Nice shot. :)

Mike

Pretty good Fay. Not sure about the Christmas Card stars you've 'created' there though ;)

Thanks Rick. I think the Christmas card stars could be a woman thing. I am not sure if it is "pure" to put them on.

I will remove the christmas card stars, to be more correct.

Does this mean Santa won't be coming  :cry:

Perhaps this is more subtle

Great image Fay, did you have any luck with the FR on the ED80.

I like it - that's a nice image.  It's a fascinating target - it really does look like a bubble. 

Fay

Mick, you can still put your stocking up for Santa. I have asked him to make you a special case.

Thanks Mark.

Tony,

I have not found the correct combination. I am more interested in the FR suiting my SX as the Canon has a wide field of view anyway, although I do not have the correct adaptor for the Canon yet. Tony Sizer was going to investigate an adaptor.

I read an old advert that Adirondack was going to do a special FR for SX cameras whereby you had to remove the tube in front of the chip & attach the FR first. I contacted them & they said that they only did a 0.5 FR, of which I have a 1.25 one of those, & they are not sure if it would work with the SX as I would need "inward travel" for it to work.
It seems that a FR is not all things to all equipment. It has to be carefully worked out for the camera & scope used.

My 0.25 FR produces a lot of vignetting, I think because I cannot get it near enough to the chip, so I thought that a 2" would give a result.
I will be interested to see how you get on.

They are artificially added in using Astronomy Tools.

I agree with Rick that the first version shows more detail and is less saturated.

Fay,

Are you taking about a Focal Reducer for the ED80?  If so the Astro Physics one work and is easy to use.  Also I thought you had a ZS66 with a FL of about 350mm I think, I'd use this rather than spending another £100+ on a good FR.

Lastly ou have Ha and CLS Filters, you can do a false Colour image if you use Ha for Red and CLS for Blue and Green, just a thought.

Nice image by the way.

Chris

Fay

Thanks for all that Chris. I will digest the info

Lie, say you used a newt with thick secondy supports then your image is ok.

I like it, I also remember John and Mike posting images with spikes????


Chris

P.S. John where you been hiding?


Fay

I only meant the big star to have spikes, I did not want the others they just appeared. I wanted a subtle look but I had a bit of a problem with Astronomy Tools, going thru about 100 actions on the image, & not knowing how to get out of it.
I will try out what you have said, John, I did not know about that.

Hi Fay,

That is a really impressive image, I can't believe you took that at 5:30pm in the afternoon !

Robert

Mike

Yeah I have to admit that taking that kind of image in the daytime is pretty impressive. I take it you have a sunlight filter?

No, but it was just about dark, with a lot of moonglow

I must add, that a while ago, Chris suggested using Push Hard Dummy, for guiding. I thought he was taking the mickey.

I was having trouble with K3 guiding. Kept freezing, nerve wracking graph to watch  etc etc.

I wanted to use Maxim, but, I could not get the guiding going with the webcam. Mike, I read somewhere that Maxim does not support webcam guiding, I could be wrong, but anyway, I could not get it to work.

John reminded me of PHD & so that is what I used. It is very easy to setup. no aligning the webcam. It calibrates when guidestar is chosen & a bleeper goes off if the star disappears, if star is too saturated or guiding goes off for some other reason. I have done 10 min guiding with it. It may need a bit of fine tuning, as I did have to delete 4 of my L subs of the bubble.

Sunset's before 4:00pm at the moment, so 5:30pm is a good hour and a half after sunset. Plenty of time for it to get dark! ;)

I really hope it does, otherwise I've got to spend some more money :(

Who me?

I prefer the 1st one by the way, reminds me of mine.
