Narrowband Tarantula

[codemonkey]

Well, I'm finally imaging again. Been a while now, with the birth of our first child, and issues with the new observatory. Still not automated yet, but at least it's up and I can do some imaging.

This is only 3hrs of data, Ha and OIII, shot last night and the night before, through a full moon and thin cloud, so it's a bit shallow. Just nice to be imaging again!

It is nicely composed and you've picked up all the brighter stuff :) Sometimes you've just got to image even if under far less than ideal conditions :)

That's it, I'll take what I can get these days. Thanks Colin :-)

Good to see you getting back into it Lee.

[codemonkey]

Thanks Glen! :-)

[Slawomir]

Congratulations Lee on your new baby!

It's also great that you are imaging again. I'm also a bit stuck with imaging at the moment; since the neighbours finished construction I have hardly any sky left to point the telescope at.

Very nice spider

Ah man, that sucks Suavi. As if it wasn't hard enough shooting through all that light pollution. I'd be itching for a remote setup...



Thanks :-)

So many Tarantula images out there is hard to do it different. This is, I like the dark aggressive monster 3D effect, excellent Lee, top work!

[Shiraz]

fine smooth detail, exemplary stars - nice.

looks like your system is working really well.

[SimmoW]

Welcome back Lee! Yes a broody critter has been revealed here!

That sucks Suavi! Sorry mate, you gotta move!

[codemonkey]

Thanks Ray :-) Actually I'm still having a bunch of issues, including something that's causing stars to go from 2.5" in one corner to 4" in another, in addition to issues with SGP and my auto focuser. Never ends...

Edit: Just got the howie glatter + holographic piece into the focuser. I think my focuser was a fair way out of collimation, so I've adjusted it. Since I have no idea what I'm really doing, I expect things to be either much better or much worse after this.



Thanks Simmo! :)

I may yet gather some more data on this one... see how I go.

[Atmos]

Lee, this is what it looks like when it is out a bit. The brighter rings are not centred equally inside the dimmer outer ring.

If you rack out your focuser all the way the outer ring becomes smaller and it is easier to see when it is perfectly centred :)

[codemonkey]

Excellent, thanks Colin, that's what I thought :-) The bright rings were close to the edge of the dimmer outer circle on both X and Y axis - I centered it up pretty well, relative to the dimmer outer circle.

[Atmos]

I eyeballed mine a few nights ago and last night CCD Inspector tells me I was 0.0x and 0.1y off, 4% tilt down at ~270º.
I visually have a fair bit though so I need to double check a couple of other adapters as I am getting some pretty horrible stars down on my bottom left corner (only that corner).

Layering takes 5 minutes and is fantastic :)

[codemonkey]

I found CCD Inspector to give me variable results... improved through averaging, but I never quite trusted it.

[Atmos]

I've had the same results, single subs generally aren't that accurate but when averaged it's pretty good.

A very menacing looking spider, Lee :thumbsup:

[codemonkey]

Thanks Rick! :)

[Placidus]

That's quite something, Lee. Very sharp. Great processing of the Tarantula itself and embedded cluster.

[codemonkey]

Thanks Mike :-) Not the sharpest thing I've done, of course it's quite low and I actually didn't even decon this one. I probably didn't get enough data here to do it justice, but I'm forever excited to move onto the next thing.
