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.

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 !

Best regards,
Tel

Thank you and to Tel, at some point during these last two years, I learnt from you. 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.

Very nice captures Haseeb. I hope to get a chance at Saturn tomorrow morning if weather permits.

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 ?

Best regards,
Tel

Definitely an improvement over mine Tel. 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.

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.

Regards. Peter

Thanks Peter. I guess the conditions were good as you rightly point out, the colours have indeed come out to my liking.

Finally, guys ! A prolonged clear night here in Southern England. It was a good job I attached that ball of string to my dome ! According to my HC, the last time I used it was the 4th. March !

Messier 51. (1st. April 2013)

Nexstar 8i OTA on a Skywatcher HEQ5 Mount at f/10.
Camera: Canon 350DSLR.
Captured in Stark Lab. "Nebulosity 2".
Guided by Meade DSI Mk.1 and Phenix 102mm Achromat at f/5.9 using Stark Lab. PHD software.

10 subs at 2 minutes each plus 5 subs at 5 minutes each.

Stacked in "Nebulosity 2". Processed in "Nebulosity 2" and P/Shop CS2.

Many thanks for viewing.

Best regards,
Tel

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

Many thanks, guys !

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.

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

Tel, beautiful shot of M51 (compare with my "lame" attempt in the "beginner" AP thread here)!

It's a great demonstration of the capabilities of the NexStar, and your talents with processing the photons afterwards!

Wow, for just 45 minutes of exposures, that's an excellent image and well processed, especially considering your are imaging from a city.

Hi Hdt,

Many thanks for your kind words but please don't "knock" your own imaging attempts. Remember though, that for you it is a lot more difficult than for me to produce images, working, as you currently do, from the standard, exposure time limited, guiding prevented Alt./Az. and with spur gear drive !

Look again perhaps at your image and compare it with this attached one I took of M51 with my then Meade DSI Mk.1 Nexstar 8i combination back on the 27th. March 2007. I'm sure you'd agree you're a lot further ahead than I was at that time !

Best regards,
Tel

Likewise, many thanks Milby and Haseeb for your kind appreciation !

I would add though, Haseeb, that I'm luckily not "city bound". I live on the periphery of a small-ish (Pop. ca.7000) town where the light pollution, (Sodium street lighting), presents no real problem under good clear skies.

However, given much in the way of haze over the town, and their orange glow can make its presence felt. It's time like that I'm grateful for my Ha and Olll filters !

Best regards to you both,
Tel
