I would like to put the 8SE OTA and its longer FL on a GEM but that may be better suited for braver souls with a CG5 and for me that means adding a beefier mount to the collection at some point down the road. I bought this CG5 used to dip my toe into AP and some nights I justed wanted to scream but I will take the past few good nights as compensation!
Tel, I think it is surely the other way around!!!
I want to add some HA data to the HH and see what effect that has on the image. Maybe tonight if I am so lucky.

Seconded! Simply stunning and worthy of publication.

Last night the conditions were very still so I went for it, as they say !
'Scope: Nexstar 8i OTA on a Skywatcher HEQ5 Pro GEM

Hoping to join you in getting out tonight, looks to be a good sky given the forecast(where have i heard that before).
Might have a go at IC405 the flaming star nebula, here`s hoping.

I, like Tom, am hoping to be out there tonight.
Thanks for posting.

Looking at George's HH and Flame Nebula prompts me to get back to some DSO imaging
Very true - some lovely captures there George.
at the moment Jupiter is so tempting particularly as it's riding so high in the British skies at this time.
Snap! Considered trying my hand at M45 last night but decided to have another go Jupiter
Scope: Nexstar SE 8 OTA on a Skywatcher HEQ5 Pro GEM
Camera: Philips Webcam SPC900NC plus X3 Barlow.
120secs. at 30 fps.
Stacked in Registax with applied Wavelets.
Final processing in Photoshop.
Spent a lot of time trying to get the collimation right and (hopefully you'll agree) got my best Jupiter to date. For some reason the processed images look better on my laptop but I'll have another go after work. Still I'm quite pleased with this effort...

I'm quite pleased with Jupiter, considering that I didn't use a barlow & haven't adjusted the image apart from cropping it (single exposure, ISO 200, 1/80 sec):
I also had a first attempt at the Orion Nebula (single exposure, 4 secs, ISO 6400):
I must admit I was a little dissapointed by the star trails, I took several other longer exposures which had more detail but the trails were awful! Am I expecting too much, or is there anything I can do to correct this? The telescope was level & I aligned it via the two-star method, I've also entered my full lat/long for my location. Would I get better results if I used a 'piggy back' mount & a 300mm lens? Any help would be appreciated!

How are you activating the shutter on the camera? Manually, via remote or timer? Could it be the mount wobbling after you've touched the camera?
Posted 06 December 2012 - 06:37 AM
Apologies for the basic question, but do I need to do a 'polar align' and/or use the wedge? I've only used the 'two star align' method so far although I've tried to be very careful each time: I levelled the telescope, entered the precise time, lat & long, & used two stars approx 90 degrees apart, and each time it's stated 'alignment successful'. However, it doesn't seem to work very accurately & often it's 5-10 degrees out?
This is my first telescope and I'm still not sure what I should expect from it! For example, when I've viewed the nebula via the 10x 'liveview' of my camera the main stars were clear, but were gradually moving across the screen, so I needed to keep adjusting it. Is this normal?

I did have a fiddle with your image and got more detail out of it, however as you know, my colour skills are zero and i could not get it right, but there`s definitly more you can bring out with another process.

As for your star trailing problem, i will leave that to those that use the alt/Az mount, i can say though, that several here on this thread have managed 20 second exposures, and a bit more in some cases with great results, i`m sure others will point you in the right direction to help you get the most out of your mount, so hang in there.

Excellent for a single snapshot Robin.

I have a Nexstar although once I decided I liked astrophotography I abandoned the mount! I'm not sure what setup you have - just a standard nexstar?
The usual things I remember checking were the mount being level, then the balance and stability. Others on here have had great results with the mount for at least 30 seconds of exposure so it can be done.
Have a read of some of the stickies - find the balance point of the scope and hang something heavy off the bottom of the mount.
Having the anti-vibration pads on the tripod feet helped dampen movement. A breeze could cause trails too - the 8SE is a bit like a big sail on the nexstar mount!
Check the setting for tracking rate - is it on Lunar or Solar?
I'd say have a go with the 10 exposures on timer. It may've stablised by the end of the image run.
Finally, don't dance around on the patio in excited anticipation of your images - that doesn't help!!!!
Hope some of this is of use.

Think my laptop is doing odd things to my images. Will try again later.

I went for a target that i`m pretty sure Tel mentioned to me a while back, that being IC405 the Flaming star nebula, i cannot get the entire nebula in my FOV so here`s a close up.
IC405 is a combination of emmision and reflection nebula and lies in Auriga approx 1500 L/Y away, the large star in this image, is a giant blue star, AE Auriga, and is responsible for the illumination of the nebula.
Image comprises of 8 X 20 minute subs in mono Hydrogen Alpha.
Imaged with Skywatcher ED80 DS PRO refractor, Atik, 314E CCD and 7 nm Baader Ha filter.
thanks for looking, this is my initial process of the data, so will most probably re-process at some time.
