June 2021 - Anybody playing tonight


Recommended Posts

The nights are getting shorter and shorter. I probably won’t do any nighttime imaging for the next few weeks but might get out the binoculars or the Dob for some visual. I will set up for daytime imaging of the sun though so the gear will still be in use.

Just finished my first hour of Ha data on the Cave nebula. Guiding is quite good, between 0.6 and 0.7.    

Maybe I need to call the topic "Anybody playing today" as I set up the solar rig and just did some white light solar and captured AR2827. Rig is William Optics ZS73 with the Altair Astro Hershel

Did some stacking today to see how things are doing so far.  Can;t find any detail in the OIII, and what there is in the Sii just doesn't show through even combing as HSS.   So I had a go wi

Maybe I need to call the topic "Anybody playing today" as I set up the solar rig and just did some white light solar and captured AR2827.

Rig is William Optics ZS73 with the Altair Astro Hershel solar wedge

Captured with Sharpcap and processed with AutoStakkert and Registax.

Coloured with Photoshop CC2021. BTW they have removed the ability to save as jpgs in Photoshop!

And here is a closeup view of AR2827 with ROI set at 800x600

I forgot to say the camera is the ZWO ASI183MM with a Baader Solar Continuum filter in place.

They haven't removed the ability to save images as jpegs Terry. They have just messed around with the way to save them. I have no idea why, it took me a while to figure it out. What you need to do is change the mode from 16 to 8 bit. The options to save as jpeg as well as many other file types then becomes available.

Wow, June already.  Was out imaging last night, 2nd night on this target, but didn't get much at all the first time.

 

One of my screen shots from last night.  Can any-one guess the target?

I would say it was the Clamshell nebula, but it was an educated guess. 😂

Well I'll be darned. They must have done that recently and I've not noticed. Thanks for the headsup Brian.

I have used Photoshop since CS3, and you have always been able to save to a jpeg from a tiff file. I have no idea why they fixed something that wasn't broke. You can't use the save as command on 8 bit PNG's either if you want to save them as a jpeg. You have to use the Export As.... command, or the Quick Export As JPG.

Correct.  Bearing in mind I am Bortle 8 and imaging with little Astro dark it is going to be a challenge.

Did some stacking today to see how things are doing so far.  Can;t find any detail in the OIII, and what there is in the Sii just doesn't show through even combing as HSS.

 

So I had a go with HaRGB this afternoon.  I had only managed to capture 2 subs each of RGB so far as was planning just to use RGB for the stars, and was expecting another couple of evenings at it.  The HaRGB looks tons better than the SHO or HSS.

 

As I say this is just a practice process as hoping to get some more data.

That's starting to look very well Carole. No joy for me for the next week, as those Atlantic lows have parked themselves off the west coast.

@gabs great to see your Jupiter earlier!

cheers ! nothing special but I enjoyed observing it

Running a trial G2v sequence on M13. I tried one a couple of nights ago but stuffed it up royally. Hopefully tonight's will be better.

Will be interested in how you did it and how it turns out....

The initial calibration consists of taking short exposures of a G2v star that's high enough so that atmospheric extinction is small and measuring the intensity for each of the R, G, and B filters. I only did this to a first approximation so had equal exposures for R and G, and 1.75x for B.

 

This is the result of taking 6 subs each and stacking the best 5 in DSS, followed by basic processing in AstroArt 7

Could put a bit more blue into the background as it's a bit yellow.

Yes, you're looking at 0.5 sec or so.

 

@Jkulin and @peter shah can give you chapter and verse.

Hi Dave, 0.5sec sounds about right, with my kit I used 1sec finally, but my RC is slower than your DK, here is my capture settings in SGP, from that I calculated the least saturated subs and used them to calculate the ration out: -

BTW Dave the propeller in your capture is exceptionally clear.

 

This was my M13 really demonstrating how much faith I have in the G2V principle: -
