Great Orion, Chris. That could be a Yes album cover! Question: i see you use PhD. Do you find it superior the maxim autoguiding?

Chris, wonderful image of M42, like the combo of HDR/RGB processing,not something i`ve tried or likely too do, but you should get this one printed out and framed to hang on your wall.Very nice :bow: :bow: :bow:

best regards,

Tom.

Thanks guys. I appreciate the kind words. I posted that image all over after I finished it. Honestly I couldn't believe I took it! I can't claim the processing technique though. It's also the first picture I've printed!

Milby, honestly, I have had much greater success with PHD than Maxim. Some of it is just frustration with understanding how to modify MaximDL. The manual sucks, to put it lightly, and trial and error seems to be the only method. The SBIG has a built-in guider... but I've been having so much success with my lodestar/finder-guider rig that I haven't used it. Once I find something that works... :D

Hey guys, been a few. Great stuff showing up in here! I grabbed a few quick shots of the comet last night and figured I'd share. 30s unguided images @ iso 400 w/a Canon T2i through a SVR90t mounted on an HEQ5. I think it was ~5 minutes of total exposure and I forgot bias frames so it's a bit noisy.

Hi all.
Here is a moon shot taken with the Nexstar 8 scope . It is mounted currently on a CG-5.I used an Imaging Source DMK 41AU02.AS camera and a Celestron 2 times barlow.
The seeing conditions were above average here ( I think)
I still use and enjoy my se Alt/Azm mount for my solar imaging. Link

Awesome shot Ugbitts! Glad to see someone got a good frame or two, I haven't had clear skies in weeks.

And John, great shot as well, fascinating detail.

Thanks for the wonderful Comet image Uggs. Like Tom, I've been tracking it for days but can't manage to glimpse it for love nor money.

Great Moon shot John. I never tire of looking at old Lunar.

Thanks for posting lads.

Regards. Peter.

Had my first views of this years Saturn and could not resist. The full moon too was out and that too I could not resist, so made a mosaic and missed couple areas.
Both images taken with DSLR on C6-SGT, barlowed. Hope you like it. Processing minimal.

Hi Haseeb,

A lovely image of Saturn. :bow::bow:

With the weather over here being what it has been and indeed still is, I've being trying to reprocess one of my Saturn images I took sometime ago and can truthfully say, that for all my "messing", I can't match that one of yours above !

Many congratulations ! :bow::bow:

Best regards,
Tel

Thank you and to Tel, at some point during these last two years, I learnt from you. :bow: I wish I could have your processing skills as well though.

I tried to process Saturn but I seem to either overshoot the exposure or induce some sort of distortion. Maybe its the file size? Btw, I stacked using Autostakkert II.

Hi Haseeb,

Perhaps try another "stack" in Registax 6 for comparison ?

I took a look at the image and you are right: despite the good capture, there's something within it which makes processing, particularly sharpening, difficult without incurring a lot of "noise".

I played around with it both in Registax 6 and P/shop but the best I could do was mainly to crop it slightly and place it at a slightly different angle; (sometimes a different perspective on an image from the original, can fool the eye to advantage).

Here's what I managed to produce. Is it more in keeping with what you were hoping for, or, then again, perhaps not ? :idea:

Best regards,
Tel

Definitely an improvement over mine Tel. :bow: The CD is even more prominent and the object itself a bit sharper than mine. I also like the angle / tilt which gives it a more planetary look. I have downloaded it. :jump:

Great Saturn image Haseeb. I like the amount of colour (shades) you've manage to capture both on the disk and in the rings.

Thanks for posting.

Nice capture Tel :bow:! Total imaging noob question: Why use the DSLR instead of the Atik CCD you have?

Many thanks, guys ! :bow::bow:

It was just nice to be able to practise the "Black Art" once again !

As to why I didn't use the Atik 314+, James, I always use Rod Wodaski's "New Astronomy Calculator" to give me the appropriate FOV for any object I wish to image and, in this case, it just so happened that M51 fitted better into the frame, (FOV), presented by a combination of the Nexstar 8i OTA at f/10 and the Canon DSLR, rather than any other combination of' scope (my 102mm Achromat), focal reducer etc. using the Atik.

Perhaps try it yourself if you do not already do so ? I'm sure you'll find it a very useful tool which will accurately predict how your final image will look. :waytogo:

Here's the link to the free download should you be interested in using it.
