Astro What? - Astronomy & Astrophotagraphy

Astro What? is a place to discuss astronomy and astrophotography, from beginner level (where I am at) to complex discussions.

Have recently brought the site back up after letting the domain lay fallow due to not having enough time to generate content for it, but that should be changing since I have new hardware to use to generate content with.

We are running (currently) XF 2.2.10 and utilizing the XF media gallery and resource manager. In addition, we are using Bob's fantastic Showcase, Articles Management System and Classifieds.
The style is from PixelExit and has been modified somewhat by me.
We have a grand total of 1 user (me, 2 if you count my Admin account). As I said, just starting over again after letting the site lay fallow for so long.

Love it! I would make the starry background fixed so it stays put as you scroll.
Thanks for the suggestion. The main page background was easy enough to do.. but the header is a different matter. Will probably have to get @Russ to give me some hints.. ;)

EDIT:
actually... didn't... simply took modifying Header/Logo row in style properties to reflect background:none; in the extra CSS/LESS code box.

Nice looking forum, keep up the good work. I've never been a big fan of dark style but I actually like this dark style. Fits the subject and the red highlights it well. Good luck with a successful forum.

Nice forum and good subject. My forum has a subforum for Astro photographers too ;)

Good luck
Thanks. It's a field I've been interested in since Jr. High but haven't had the time nor spare money until the last few years to get into it.
I'm just getting into the field... still finding out what "extra" stuff I need to get besides the base. Grabbed this single image tonight, but am off on back focus.

Using what camera ?

Using what camera ?
ASI485MC through a NexStar 8se (need to get a reducer/flattener for it). Got some spacers coming in for the camera... they never ship enough until you get into the Pro model cameras. The only processing done to that image was it being scaled to a smaller size from original.

Get a decent camera with an adapter for a better results, maybe a full frame.

The ASI585MC (don't know why I put in 485) is not a "low end" camera... in fact, it's one of the more expensive non-cooled (Pro) planetary cameras from ZWO and is is, in many ways, better than the older stuff that is out. I've got the ASI533MM with filter wheel that is reported to do better than the ever popular 1600MM, without many of that camera's warts. The nice thing about both the 485MC and the 533MM Pro is that neither suffer from amp glow. Now, when I get better, I do plan on getting an ASI6200MM.... but the cameras I have are perfectly adequate for almost all astrophotographers. The problem is not camera... it is back focus - which is not a camera specific issue (all have to be within their optimum range). If your camera isn't in that 55mm +/- 5mm comfort zone, then you can't get a good focus. And that image is a single non-stacked PNG capture. Full frame is nice when you are doing diffuse nebula. Not going to spend almost $7K (ASI6200MM Pro w/wheel) on a camera, when I'd be better served by a REALLY nice EQ mount. ;)

You know better about Astro photography. But personally I will attach a camera to the telescope and use live view via computer for better focus and details.

Wonderful photo and a great idea for a forum. Good luck, Tracy! :)

Nice.

I have been taking shots for 35 years and also dabble with a telescope.
I haven't yet got around to combining the two.

I assume you've already seen this @Tracy Perry.
Nope, not a moon shot in color detail... but they are right about the thousands of shots and the stacking a good image can take. I've got my RPi set up to shoot 50 with Luminance filter, 50 with red, 50 with green, 50 with blue, 50 with OIII, 50 with H-a, and 50 with S-II in one session with an average 2 minutes each. I'm still playing with the exposure times, and haven't really gotten a chance to capture anything because almost every night since I've gotten the cameras have looked like this around my area.
IMG_1007.jpg

I've only really had the site going for around 2 weeks, and have had 3 new users join in the last 2 days that saw my avatar and home page info in my profile from over on another astronomy related forum I participate in.

I've played with cameras since I was 20 (I'm 58 now)... but never really got into the astro aspect of it. I've got Nikon D7200 that never wanted to play nicely with my scopes and I cursed every time that I hadn't gotten a Canon instead - their API to software interfaces that allow timed exposure is better than Nikons.

<edited>
for more realistic amounts since 1-2 seconds were not enoouh... reduced the number, increased the exposure time.

I've always been Canon.
Only reason I went with the D7200 was the better 1/2 already had a ton of lenses for an old D40 that she used to use, but it started having issues.
If I was looking for DSLR now, I'd be leaning towards the D850 if I was staying in the Nikon family or if Canon, the EOS R.

But since we already have the D7200 and it does great for terrestrial uses, I have an ASI533MM Pro with 8 position filter wheel and an ASI585MC for telescope use.
The neat thing... the RPi I use to control them will also control my Nikon better than the software I purchased to do that with... so while shooting deep sky I can also be grabbing some wider field images with the Nikon mounted on a simple tripod.
I also have the ability to connect those cameras up to the Nikon lenses... but you have to use manual focus on them.
