3 hour eagle

[Peter.M]

Last night Paul Haese invited me to do some narrowband from his dark site. After work I packed up my stuff and started the drive down. I got about 50 minutes into the trip and realized that I left my laptop at home and would have to go back for it. On the way back I got a puncture in one of my tires. Around this time I conceded to the astro gods that I wasn't going to get down there.

Instead I decided that I wasn't going to let this get me down and took some hydrogen alpha from my house.

This is 3 hours of 20 minute subs taken with my 8 inch F4 Newtonian on my heq5 pro. I had the QHY9 cooled to -35 (dam it was cold last night).

Currently I only have a hydrogen alpha filter, so i cant do full narrowband images. Thats next on my to buy list.

Well I can sure relate to forgetting things on the way to Paul's place. Very nice image. There's a bit of white speckling on the hi res version. Is it fully calibrated?

Nice shot Peter.

Just flats graeme, I didnt have any 20 minute darks at -35 to use. Not that often that adelaide is cold enough to get to that temp.

The cooler was only at 65% aswell :lol:

Thanks everyone

Nice effort, you missed a very cold night down the house you guys. Probably not a night for standing around outside. It got down to 1.5 degrees.

I reckon with this data you can crank up the contrast though. It looks a little flat to me. Guiding looks good but a field flattener is probably needed. Glad you got some data despite the little set backs. Getting flat tyres is not much fun.

Very nice work Peter.

Great photo Peter.

Amazing detail.

There's just something about monochrome Ha shots.

Thanks everyone, im slowly progressing. I think most of the field curvature is due to some collimation error. I have processed the data again with more contrast, however im not sure which one i like better.

Here is the new one for those who want a look.

Also included is a photo I took on the 26th of September last year.

Yes I like that better and you are progressing well. Keep at it.
