Congratulations for SPoD, well done, with those images we should just give up solar imaging

TareqPhoto

You and others are lucky to witness the totality, i don't know if i will see this in my life again, i think it happened once in my region and i watched it visually barely as i didn't have any solar glass, and i was in photography only so i only captured simple partial eclipse, but good job from you,...

Nice setup Rick, and even nicer results, great job!

What is the difference between Ca-H and Ca-K?

TareqPhoto

This is impressive, well done!

TareqPhoto

You will need around f/35-f/37 to get critical sampling with that camera in that bandwidth, conversely if you used a ASI183 you would only need around f/15. (anyone correct me if my math is wrong here please!) If you don't want to use a barlow to reach that, you can also mask down the aperture to a...

TareqPhoto

I like this kind of comparisons, more please between those two T Barlows.

As requested: :D ca sun 130424 colour.jpg There is an increase in limb darkening. Amazing, thank you very much! So even if it is under sampled i still like the results, Lunt CaK is a fun and i am happy to get one at good price finally, it was a dream for me to get CaK, so i will try to find a way f...

PhotoFiltre 7: Gamma, contrast and sharpening. 10 seconds?

Yes of course, i uploaded it for all to play if they are willing to.

Thank you very much, this is the best i like the most, i hope if you can colorize it too.

TareqPhoto

Also, what is the best way to make a perfect focus if i don't have an autofocuser or a motor for that? I mean how could i make a perfect focus manually, so even if i can make a right sampling then bad focusing will also ruin it.

TareqPhoto

As i mentioned, here is another image file of the same time, but it is cropped with ROI, not sure if this is any better focus or details, if not then i better find a way for correct sampling then try again. 2023-12-03-1103_7-U-G-Jup_lapl3_ap29.png Here is a link to compressed one of the same above, ...

Cool, thank you very much!

Hi Tareq, Just a 1:1 crop, a simple Histogram stretch and a tiny bit of Unsharp Mask. Nothing else as I still do not understand Over- or Under sampling :lol: Important for you is to focus near perfection. 2023-12-03-1106_6-U-G-Jup_lapl5_ap30.jpg Hi Rainer, Actually i have another image i did with c...

TareqPhoto · Re: jet transit during eclipse 8/4/24 Nice timing indeed!

Nice timing indeed!

Hi, Congrats all who captured the Eclipse, it is definitely the best unique astro event in the human history. Can you please process my old image i was taking last year so i want to see how good it is? I uploaded the stacked image out from the camera, it is same setup i used for the image i won here...

TareqPhoto

I hope you will figure it out, i have same camera but ZWO brand, i was thinking about Player One version but i saw an offer before P1 did and i got it. I don't have that Ha scope, but once i manage to get a proper scope to use my Quark then i will put this camera into use and see, mainly i use Sharp...

TareqPhoto

Amazing image and nicely done Mark!

TareqPhoto

For now i am relaxing, and summer is soon coming, i am slowing down, i can just rethink my list and see what i can do, kind of i have another issues in life, and while i am stopping and do no imaging i just manage to get budget for astro, so i can't just wait and wait with no imaging and saved budge...

Hi Bob, Sorry i disappeared, we had our holy month and i got busy in life. Well, You have all valid points, and i agree, it is just me learnt the hard way that either i have to go for something nice great from beginning or i have to accept that i will waste more money in the way, nothing about start...

That is why i keep asking too much questions, sorry to say it but i feel like there are people who are willing to blow money in the air buying and buying to test and replace later, i can't imagine how much i will spend buying one stuff and another only to find the right tool.

TareqPhoto

The Altair filter having only a 2 nm bandpass is going to give better contrast and more Gband detail than my wider 10nm Edmund filter does. In time I will replace my Edmund filter with the Altair one. My Edmund filter is mounted. Marty bought the filter and mounted it afterwards in a cell he purcha...

TareqPhoto

What is this filter tilt holder/mount used for? How is it different than other ones available such as from ZWO and Daystar? It is used for tilting ultra narrowband CaK filters to get them on band or throw reflections. The tilters from ZWo and Daystar are used to tilt the camera not the filter. Comp...

Now you have to tell me why is that IMX432 the clear winner out of the three cameras please?
I'm from the Czech Republic. The IMX432 has an optimal pixel size for a given focal length.

Excellent, thank you very much!

Hi all, I am trying to follow a dream that i hope it will happen so then i can dream about all kind of equipment i can for astrophotography and more, so i will ask questions to prepare myself if the dream happens, if not it will be just curiosity questions after all. 1. Which Lunt scope to buy for H...

TareqPhoto

The holder can be managed, now the question is, from where to get that ERF glass? And which size? The optic itself is expensive, so the holder frame isn't a big deal anyway, and i prefer Aluminum or metal for sturdy or rigidity, i don't know if those 3D printing materials are strong enough to last l...

TareqPhoto

Dennis makes a very good point. The Sharpstar 94 has a rather fast focal rato to be used with a Quark, it won't show a lot of contrast. With this in mind, I would recommend a 75mm Baader DERF as an ERF, or, a different scope. Mark What do you recommend as a different scope for the Quark either with...

TareqPhoto

I am trying to make a last or final decision about which scope i want to use with my Quark "Combo" which is without integrated telecentric Barlow, sometimes i think the achromatic is enough, another time i believe the ED doublet is better, and then i feel that a triplet is just overkill an...

TareqPhoto

"more accessible to amateurs", means that Edmund is just for professionals more?!!! The G band has a standard 1.25" thread on it so you can just thread straight into an eyepiece . camera barrel etc, the edmund is unmounted, so you will need to make a suitable holder for it. Ah i see,...

Nice disk images Rainer, hope no much rain your side so the sky is clear enough for you!

TareqPhoto

The Altair 430nm filter has made Gband more accessible to amateurs. But does that means the quality is same as or less than Edmund Optical one? I won't waste time or money to buy Edmund version if it is not making any big improvements over Altair for example but i am open to one of them that can gi...

DeepSolar64 wrote: ↑Wed Mar 06, 2024 6:02 pm It is. I bought my Edmund filter about 3 years ago from Marty Wise. I think he custom ordered the filter and them mounted it in a 1.25” cell. This I think was before Gband was commonly and affordably available. The Altair filter has changed that.

You are lucky, having all perfect choices solar filters, so lucky, now i only need to add WL wedge because i can't afford Lunt Ha scope or etalon.

TareqPhoto

For CaK you stopped it down, while for WL you didn't although using same scope and camera, why?

TareqPhoto

I think you will like the Gband filter. The Altair model is better than the Edmund Optical filter I have. Lower bandpass. I only see Altair model anyway, i didn't know about the other model until you mentioned it, i am going for Altair version because i believe it is narrower so more contrast maybe...
