Flamin Star, and a laser test...
Oct 30, 2020 15:51:07 #
So, I finally got the gumption to get my fanny out last night.
After fooling with a Blue Laser, compared to my Green laser, I think for me, where I am, in a hole surrounded by paranode light burners, and a nearing full Moon (oh Joy!), the blue laser is a little too dim for my eyeballs.
But it does work well with my Main camera. Seems to do less distortion, as you can see.
But for me, it seems to be harder to actually see the beam of blue light. But hey, first night, short test, no fair.
I actually got the blue to use with Binoculars, which I'll do tonight, I'd suppose.
After fooling around, and posting to a friend on the Losmandy forum, I forged ahead and got onto the Flaming Star Nebula and did some Narrowband Imaging in Ha7nm. I ran a bunch of 120 second images, stacked in the Infinity camera program.
Feel free to download and process if you would like.

Nice Shots SonnyE.
Our eyes are most sensitive to green light so that might explain the difference you see, particularly if both lasers have the same milliwatt output.
Looks like the HA works well on the Flaming star nebula.

They are very close, in certified mW output.
One guy asked why the Green picture looked different than the Blue. (More specifically why the Blue had a darker background.) This was my reply.
I was just trying to give a comparison.
Last time out, I put the Blue laser on my Astro Binoculars for some play, and to see how it worked for observation. I think the Blue is a real winner, as it does not mess up my night vison. Just a nice visual pathway for aiming.
Except for the moon. The obnoxious Moon was so bright it overpowered the poor little laser beam.
But for aiming, and especially during alignment, these narrow beamed lasers are my new favorite tool.
Once in a while, I might have to wait my turn with aircraft, but it's ok, they're moving quick enough it isn't too much of a bother.
Another friend says the Moon is a good time to dust off the narrowband filters. So that was another "push" to roll in the HA7nm Craig recommended to me. It sure pops out the red in the nebula's that the Moon and light pollution messes up.
It's the only narrowband filter I currently have. But the newer filters sure have me drooling...

Hi SonnyE
I've heard that the narrow band filters are great for light pollution (including Moon light) but you have to take much longer exposures. You can also produce full color (false color) images using HA, O3 and S2 narrow band filters which is what they use for the Hubble pallet. I hope to try it eventually. Currently I've still been working on getting better shots of Mars while it is still pretty close.

That's good to catch as much of Mars as you can. I've been observing the red planet now and then while running a series of images on the telescope. As well as examining the Moon's details.
I got my Astro Binoculars collimated much better, so they don't make my eyes and brain go wonky when looking through them.
I was a bad boy over the weekend.... I found High Point had the Optolong L-extreme filter in stock.
So I made an impulse buy and it's on it's way. So hopefully soon I'll have some new images to share, with better colors.
I've been eyeballing and drooling over this filter for a while now. When I discovered High Point had them in stock, I struck like a rattlesnake.
I'm an old hand at long exposures. But since I've discovered I can do these quick exposure, long runs, I've been trying that.
Hopefully the L-extreme will really pull the color details.

Hi Sonny
I had some loose change kicking about so bought one of these filters a few weeks ago, Just need some clear skies to try it out. Apparently it is good for blocking some LP & moon glow out too. The main reason I bought it was for reflection nebula & galaxies to where my tri-band blocks a majority of the wave lengths.

Hi Marc!
I checked last night to see if mine had finally been shipped, and it has.
I ordered on Sunday, but the vendor isn't eggzacery the quickest shipper I guess.
Anyway, my hope is to take my images up a notch.
I'm hoping for something like this: https://youtu.be/PHGcQ0HKRlU?t=84
And because I like working with OSC cameras, it's hopefully going to update my imaging.
I've reached the expensive baby steps part of this sport. High cost for small gain.
Edit in: I see I'm going to have bad weather tonight, according to my phone app. I wondered about that this morning.
So I go check on my filter order that was shipped yesterday. When I mined down to the pertinent tracking, I discovered why the skies will be cloudy tonight.
My filter is out for delivery today, USPS. (United States Post Office)

OK, crappy skies, and the new filter is here.
Supposedly, tomorrow night will be a gooden.
I'm beginning to figure out this weather thing.
A mount takes a month, to a month and a half of weather.
But a filter only costs one night.
So I worked until dark on my BBQ project, and will probably install the filter in the morning to my filter wheel,
Woo-Hoo!

Hi Sonny. Im totally with you on the weather related, purchasing of astro equipment front lol
I managed to get out Nov 5th & despite fireworks & 50% managed a pleasing image of which i will post tonight.
What I have found is the filter produces some really ugly halos.
Not massive panda eyes but halos all the same around the brighter red & blue stars.
This meant a lot of additional processing but the filter most certainly does its job
