Horsehead in HA

[Penfold]

My first bash in HA last night.

Only managed 6 @ 900secs but had to bin the first due to some weird tadpole shaped stars and the last due to cloud rolling in.

No darks/flats just bias.

Perhaps I should have rotated the camera round a bit to get more of the flame in.

Still a good pic though .... Are you going to add any more data to it?

[Penfold]

Cheers Andy.

Hoping to add more HA and then colour at a later date.

Sounds like a plan

These are the weird tadpole things, what causes them anyone know?

[Moonshane]

lovely image. cannot help re the tadpoles (I'm visual only). I agree that it might make a better image to crop off the flame nebula?

WOW... loving the 3d effect of the clouds behind the head, looks like rolling white water.

Very good for such short integration! Those "tadpoles" are obviously the guiding going crazy probably for a few seconds at the end of the exposure, I guess.

Are you dithering? Maybe it was a software bug that caused that.

I agree on cropping out the Flame. This image needs more integration though!

No I wasn't dithering, I'll just put it down to a glitch and hope it doesn't do it again.

Re the crop, I might try getting the flame in another frame and joining the two together... Perhaps!

Yes it needs more data, I'll try to keep at it.

Thanks all

Very nice image.

The tadpole things as said above are due to guiding momentarily on the blink. I've had it happen on occasions, perhaps a slight movement in the guide cable, or somesuch.

That's really great, which 'scope did you use for that?

Thanks Carole, perhaps it was the cable as my velcro had come off the dovetail and so where hanging loose.

Cheers Carl, it was the GT81 as I can't get the balance right for long subs on the TS, it needs an extra weight or a counter weight extension shaft.

Didn't realise I had track logging set until now and it looks like it did throw a wobbler. I can now blame the software and not me.
