That's a great image Tel. Was looking at the same spot this morning.
Thanks for posting.

Regards. Peter.

Nice image, Tel. Is that with the SE8?

flboy, Sky Beast, Peter, FebStars, please note that discussion of images and techniques is happening in this companion thread. Tel, it would help to post images for the first time in that other thread so that people could express their admiration and ask questions. Although I do agree this is a very nice sun spot, I would like to be able to discuss it in discussion thread and leave this one as a showcase. Thanks.

OK Alex, will do !

I can't help thinking though, why a "Show off your image" thread, running parallel with the permanent "Show Off your Nexstar" thread, might indeed not have been a better idea than this existing set-up.

Best regards,
Tel

M104 from June of 2010.

NexStar 8SE, Canon XSi, 340x 10 second samples at ISO 1600. About half was selected by DSS for stacking. This is around 30 min worth of exposure. Levels and curves applied in Photoshop. Carboni's tools used to remove "Space Noise" and increase "Local Contrast". Discussion thread

As I posted in the past thread, I hope I'm still welcome here.

M27, CPC800, alt/az, 2h of 30s frames at f6.3, iso 1600 through a Canon XSi in prime focus. This is a reprocess to preserve colour a bit better.

Here's my latest RGB attempt at M33.

Imaged with a Celestron 80ED/Meade DSI Pro III piggybacked and guided using PHD on a Nexstar 8i/Meade DSI Pro using BVR photometric filters instead of regular RGB. Each filter had 6 x 4 minute exposures.

Aligned and stacked in Iris, color layers combined, levels and curves and color balance adjusted using GIMP.

Especially for Alex ! Reduced colour saturation !

Jupiter on the 6th Oct. 2010.

New Morgan (Philips) SPC880NC (upgraded to SPC900NC) webcam trial.

2000+ frames at 10 frames/sec. Stacked and processed in Registax 5. Final processing in P/Shop CS2.

IR filter for the webcam omitted due to oversight but camera X 2 Barlowed.

Scope: Nexstar 8i OTA on Skywatcher HEQ5 Pro GEM.

Conditions: Sky clear, seeing on a scale 1-10: 5-6 only. Focusing difficult.

Crab Nebula. Messier 1. 6th. October 2010

20 X 60 sec. DSLR / N8i OTA on HEQ5 Pro. Stacked in "Nebulosity" and processed in P/Shop CS2.

Conditions as above but with an additional amount of indirect Sodium street light glow due to the low altitude of M1 when the image was made.

Earlier this week I had a clear night. I took 3 hours of data on Stephan's Quintet at f10 that produced nothing of note, but took a 42 minute stab at the horsehead, and despite two halos interfering in the picture it is a fair start.

Unmodded Canon XSi, CPC 800 at f6.3, 42 minutes of 45second sub frames calibrated with flats, bias, and darks.

This is a reprocess of old and new data. 4h of exposure on the dot, so 480 30s frames in the stack on my cpc800 at f6.3 with a Canon XSi at iso1600.

Above image of Jupiter reprocessed by my good friend and CN colleague Haytor. Taking it this small step further, I think he's been able to bring out a little more detail.

I still wish I'd remembered to screw that IR filter onto the webcam though !

This isn't up there with my usual standards, but as school is keeping me busy my imaging sessions are very few and far between. 52 minutes on the bubble nebula, cpc800 at f6.3, Canon XSi at iso 1600, darks and bias (Still noisy, I had to stretch way too far).

It's a truly great object to capture ! Can't remember my details, (always forget to jot them down !), but taken sometime back in July/August : Nexstar 8i OTA/HEQ5Pro mount. 6.3FR. Canon Eos 350D. ISO 800, No.subs. ? (probably 25 or 30), Exp.Time, ? (probably 90 secs.), Dark frame subtracted. No flats, No bias.

This is my first try at M27. Taken with a Nexstar 8i SE, 0.63 FR, Canon XSi and Astronomik CLS filter. Data from Oct/19/2010, around 180 x 15 sec exposures + 25 darks. No flats, i will probably add them in the future.

One of my first attempts at jupiter tonight with a spc900n and a C8-NGT 8" f5 newtonian. Used craterlet as an avi capture program. Think I got the red spot in the lower left of image. Seeing was not too good tonight somewhat turbulent with the wind.
Must try stacking 2 x2 barlows to get bigger image. ;)

Do piggybacked cameras on a Nexstar count for this thread? If so, this is my take on Orion. Taken with a Canon XSi + 70-300mm lens (at 300mm f/5.6), piggybacked on a Nexstar 8i SE. 50 x 30 sec exposures + 25 darks. Cropped to around 66% of original size.

Congratulations to Astroman68 for showing his first experimental attempts with Jupiter and the Mare Crisium region of the moon.

Likewise to Febstar for an excellent image of M42 with a well displayed trapezium area while praise indeed to ericom for that superb panoramic view of the Orion nebula and the "Running Man".

Great images, guys ! :bow: :bow:

Best regards,
Tel
