Horsehead and Flame HA First for Months

[earlybird]

I have not imaged for Months after mount and camera problems and the weather.

It was good to get out again before I completely forgot all I learnt.

The moon was out so I thought I would try some HA on the Horsehead.

ED80 6.3FR ATIK 16HR and HA filter guided by a WOZS66 DSIPro on a EQ6pro using EQMOD.

5 x 5 min and 3 x 10 min subs before the guiding stopped.

Will have to play with processing this image more, but glad to get going again.

Nice image John. Am I right in assuming that the moon doesn't wash out HA? That would be nice!

Very nice clean and clear detail, looks like you have forgotten nothing .

It is good to get out there again in't it.

John, that's a very nice image.

[steppenwolf]

Very nice image indeed, John - good tight stars too.

A wonderful Image that John. I keep saying this, but mono images of certain deep sky objects just wow me, and this is one of them

An Image very similar to this won POTW a short time back.

Splendid stuff mate.

Yes, HA imaging is good when the moon is out.

Rog. I tried the QHY8 last night after the Horsehead. I had a 2 inch HA filter on the ED80 with a 6.3 FR. and was playing with the rosette nebula.

I have to learn the best way to process HA with that camera.

I only got a couple of 10 min subs and the guiding stopped again. Three times last night it just stopped.

It is a new replacement EQ6PRO and seems to work perfectly apart from that. I was using Maxim to guide.

I will have to try PHD again, but it doensn't seem to want to calibrate on the default settings and I have tried a few things , but no great success.

The biggest problems with PHD when it doesnt want to callibrate is the value in the "callibration step (ms)" box. Shorter focal length guidescope require longer steps. My WO66 requires a value of 1000ms, but when I use my NS8GPS to guide, it only needs a value of 500ms. The callibration will fail if the guide star doesnt move at least 5% of the chip during the max number of callibration steps. So, shorter focal length requires longer callibration steps, longer FL can get away with shorter.

Nice shot John!

Great capture John, glad your problems are over - well apart from the vagaries of our weather.:-)

[Beyond_Vision]

A great capture it doesnt seem like you have forgotten anything through your hiatus in imaging.
