A little Helix

[multiweb (Marc)]

I took this last night with my Hyperstar and QHY8. 15x10min subs with a Baader 7nm Ha and a QHY8. Turned out alright despite a few passing clouds and the shinning full moon. I honestly thought that I would get more outer loops and arcs though ...faint bugger.

Slight field rotation due to PA. I haven't imaged for a while so I got right into it and skipped a bit on the basics ... and now I even got a Losmandy polar scope for the G11. how bad is that hey?

Overall a very good night. Better than tonight and tomorrow night by the look of it... Got two other DSOs from the same session that I will post later.

There's a full field bigger res (1600px wide) here.

Thanks for looking.

Very nice Marc - the outer arc shows up pretty well.

Nice one Marc. That hyperstar is working well.

Faint one for sure, the camera at f6.5 should be able to go to 20 min subs, that should give you more density in the outer areas.
Well done with the polar scope, I had to remove the factory led and put in a variable version as the stock one is too bright, plus a couple of thickness of sticky tape around the inner shaft to reduce play.... But it does make aligning childs play

Nice image Marc, it's very faint but you still managed some good detail.

Love widefields like this, you have done well. Thanks for showing us.

Thanks Peter. Yeah one of them but Mike S. got a lot more around in his version. I thought I'd get some too.

Thanks Allan. Yes, lot of fun to use.

Thanks Clive. I haven't used mine yet bit it seems to fit. It was too murky last night to see anything low in the south horizon unfortunately.

Hmmm? yes the outer areas are very faint but I would have thought 2.5 hrs at F2 and 280mm aperture would have revelaled a bit more too . Maybe t'was becasue of the Moon? What band pass is your Ha filter? What about your calibration method is that sound, there are big dark patches above and below the Helix?

Never the less a great shot mate

Thanks Mike. I put that down to skyglow and clouds (i.e. patches and noise). Calibration works fine. Will have to avoid the very faint stuff during full moon.

Nice one Marc. I am looking forward to more from your hyperstar. Thanks for the view.

Thanks for the comments Lester.

Nice one Marc. Might be small but you have managed to capture quite a lot of the outer detail. I would love to see one exposed for 9 or 10 hours from this system to see how much bounces off the screen.

[TrevorW]

Have to agree Marc, one needs to avoid the faint stuff on a full moon but then again if we did that we'd all be taking the same images

small is nice

Thanks Doug. When I have the rig on a pier I'll be able to put in that kind of integration time night in night out. Setting up and reproducibility right now is what's killing me. The details is there in the subs though but very close to the skyglow and noise. I reckon on a moonless night I would have hammered it easy though.

Thanks Trev. Can't be too picky with the nights lately. I'll take any break in the clouds, moon or no moon. There should be another good one coming our way on Tuesday hopefully.
