Fully understand your reasons for using the DSLR Tel,i did wonder about the FOV if you had tried the Atik,and whether the image scale of M63 would be suitable or not to show fine detail,you have captured some detail within the spiral form of M63 with the DSLR, so nice job mate.

Also as you say, given the position of M63 and the limited time available to capture it, i can also understand the time it would take to collect enough data in each of LRGB using filters with the Atik.Weather and conditions of course, is our nemesis and continues to be so Good job then, that our dedication to this great hobby of ours over rides all the frustration

best regards,

Tom.

Fantastic work in here guys! Tel, I really like your attempts on the Sunflower and M51 (Two targets I recently had a crack at during a brief clear night).

This is 1h55m of 5 minute exposures of the Whirlpool Galaxy captured through a Meade 14" SCT at a focal length of 3.8m. The telescope was guided on Paramount ME and captured with a QSI 583c @ -20 degrees Celsius. This is likely my deepest image to date, as many of the points of light are in reality background galaxies. This target always interested me as it shows two merging galaxies. In this case I managed to capture the full bridge between the two which is something I have failed to do in past attempts at the target.

Excellent Saturn James, much more detail than the one you posted in the Original Nexstar forum. As usual, Tel helps bringing out details and I might want to make a note of the 13 points he mentioned.

Uggs, excellent Sunflower, sort of makes the word stand out.

Excellent imaging, Uggs !

Certainly a rival for the same subject which won the UK "Sky at Night" magazine / Royal Greenwich Museums promoted "Astronomy photographer of the year competition" won by one Martin Pugh in 2012. (See attached link).

I finally had a clear night light and was able to try out my new Celestron Barlow. This is my first attempt at Saturn, so please don't laugh too much! I think that I need to invest in a Neximage....

Taken using a Canon EOS 550D, attached to a 5SE, prime focus, single exposure, image was cropped but no other changes.

I did have some better luck with the moon:

Hi Robin

Nice first attempt !

If you want to do planetary imaging you would be better served capturing a short video and stacking the images. A good program for your canon 550D would be Backyard EOS($30). You could capture and save an avi using live view and then process the image in Registax6 (free). You should also consider using a barlow to increase the image size.

Just a quick thanks for the comments about my Rosette capture way back on page 100 - I particularly liked the "**YOWZA***". Sorry for the delay, things have been very, very busy around here.

Uggs - that's a lovely M51 - astonishing detail and well processed.

Love seeing all the Saturn shots too - keep them coming.

I was all setup and ready to go last Friday night (19th) as the weather forecasters promised clear skies. For once they were right!! Unfortunately (as usual lately) it coincided with the moon. Unable to ignore it, I decided to try a moon mosiac...

Captured using Skywatcher ED80 with DMK21AU04 camera (running at 60 fps) and a Baader Neodymium Filter

16 avi clips stacked and processed in Registax 6.
Stitched in ICE (nice find somebody - Maverick? )
Bit of tinkering with in PS.
Some further post-processing by Haytor

Nice image of Saturn and as James suggested, try shooting a short clip and use a barlow.

Great moon though a bit too over exposed for my taste, but the details are sharp. Glad the ICE works well for you too.

Hi Robin,

nice first attempt at Saturn, i remember my first tries at this and your result is far better than those of mine during my first tries, The moon images are actually very good

Nice job Andy on the mosaic of the moon, agree that that ICE program that Haseeb found for us is a great tool for stitching.

Haseeb, here`s another tweak i did of Andy`s moon capture, less contrasty in this case, i`m sure Andy wont mind my posting this version, hope he and you like it.



best regards,

Tom

Much more pleasing Tom. Good effort with a jpg file. I am happy you guys find ICE easy to work with, quite cool.

I don't mind at all and yep, I like it.

I've had this problem before - it looks fine when I post from my laptop. Once back at the desktop I can see what you mean about the over exposed look.

I would correct it but its been done for me!!

A fairly miserable Iris Nebula, (NGC7023/ Caldwell 4) from last night's "Comedy of Errors" * but at least it puts this thread back on page 1.

Scope: Nexstar 8i OTA at f/10 on a Skywatcher HEQ5 Pro.
Camera: Canon DSLR D350 Eos.
Guide 'Scope: 102mm f/5.9 Achromat.
Guide Camera: Meade DSI.

12 subs at 3 minutes per sub. 5 Darks/5 Flats*
Captured, stacked and processed in Stark Lab. "Nebulosity" software. Further processing in P/Shop CS2.

"Comedy of Errors" ?

1) The guide system refused to do just that in this required part of the sky ! Checking for the problem at the end of my session, I slewed to M57 and attempted, once again, to set the guiding system in motion. No problem: it worked like a dream !

Looking therefore for an answer, I suspect that as PHD was originally indicating that the guide star I'd chosen near to the Iris Nebula had not moved enough in RA: pointing northwards, as I was, invokes too limited movement in this axis as might conceivably be expected.

Nonetheless it provoked some head scratching !

2) Then came the taking of the "Darks". This was duly accomplished without a hitch so attention was turned to the final operation; that of the Flat frames. (I don't bother with "Bias" frames).

Turning on the subdued white light in my dome therefore, and having set up all necessary as far as their software capture was concerned, I presssed the "start button" only to realise that on viewing the download of the first "Flat" frame, I was still taking "Darks". I'd forgotton to remove the corrector plate cap ( although I had indeed thrown the required white "T" shirt over it !

Cursing my stupidity I duly removed the protective cap and replaced the "T" shirt. I then rechecked the "Nebulosity" settings and hit the "start button" once again only to find that after only one frame in five into the "Take", an error had occurred and no further downloads were being made. My DSLR's battery had given up !

Hence there are in fact no "Flats" used in the attached image !

Oh Hum !

Best regatrds,
Tel

Edit. On reflection, I think the background was a little too light so I've darkened it a tad.
