Synta has manufactured telescopes for Orion for years. Orion also owns Meade Coronado so it could affect them. Currently Meade Coronado scopes are made in Mexico. Do you think if Orion moved production of Coronado scopes/etalons to Synta in Taiwan or China that it would benefit them?

Would Orion pocket the extra dough? Mexico already does it cheaper than the former U.S. Production does but the Coronado SolarMax III scopes are still expensive.

Hi James,

Well let me save you some money then... You already have a solar wedge, why buy another? Use the wedge you already have and buy the filter separately.

Find out how much the filter on it's own is http://www.antliafilter.com/pd.jsp?id=1 ... &_jcp=3_10

I bet I can find you a filter that will work equally as good, if not better for less $$$

Ok

Look at this image, the imager who is the owner of Player One brand if i am correct himself tested a prototype or a test scope from Skywatcher which is Synta for Solar, i asked him once but didn't get an answer, it has been a while, since last year, and i didn't hear from him, so if it is a reality will be out then i am not surprise if some others will follow Skywatcher for dedicated solar scope mostly from Synta, but if the price is really not cheap but cheaper than Lunt it might still an issue, but who knows, hopefully in future i can afford anything as a dedicated solar scope from 60mm aperture or longer.

If i had a wedge i will do that, but i bought both together at good price anyway, i think i saw Antlia K-Line alone somewhere, in all cases i already told James about having another wedge so he doesn't need to change or swap filters in one wedge, i might buy another wedge only for my Continuum filter.

I think the filter of this Antlia CaK filter is about $269, which means making their Wedge about $70, but they make both at good price, maybe the Wedge alone is more than $100 too, so having both for those who doesn't have anything is a good value.

Tareq and Mark,
Sky-Watcher entering the solar market may put pressure on Lunt and Coronado. That’s probably good. More competition often results in lower cost for the buyer.

I’ll probably get the filter and wedge together. Especially if I can remove the filter. I could use a wedge for each scope! C102 and AT72EDII.

James,

The decision of Skywatcher entering solar market isn't a good plan for them at this moment, they need more customers or buyers to assure they start and keep that way, Skywatcher has nice collection of affordable scopes, but those are not a big deal as so so many brands made scopes for DSO or even planetary and visual, but coming to solar side how many companies really made scopes for solar? That will give you an idea why it is maybe not a good idea for entering this market, but seeing that the Player One person used one is telling me that they are thinking about it, will they make it at larger volumes for people or not? Also will the price be affordable as i am sure making a solar scope mainly 60mm or 80mm isn't cheap, otherwise many can make those scopes.

I agree, i don't like to use one filter one wedge one scope and one camera and whatever, swapping a lot and changing and depending on one unit is limiting sometimes and also the unit is more prone for wearing off by the time maybe, i prefer to have two wedges to each each with different filters than have one wedge using it with 2-3 filters and i keep removing the filters, that is me, others might not bother having more units and just keep using one anyway, it is up to each person after all.

And i hope two things in that case:

1. I use my Quark times enough to be good in Ha imaging so then be ready to upgrade later if so

2. To have enough budget to upgrade, either to Skywatcher if they decided to make the scope and out in markets, or with current popular maker.

I hope they come out with a ultra-narrowband CaK scope like Coronado once had. An affordable one!!

I doubt they will, Ha solar has more requests, but CaK i don't see many request to my eyes

I can hear people saying 'but that is 7nm and the Antlia is 3.5nm' At this broad pass it will make no difference to contrast - think about white (red) light imaging with a 35nm or 7nm or even 3nm Ha filter - there is no difference.

So why do I say this option is better than the 3.5nm Antlia, well 7nm lets in more light which means shorter exposure time. Down in the blue, the shorter exposure time the better.

Don't rush James! ;)

Now if we use this UV filter in combination with K-Line or Synthetic NUV/CaK filter, will that make any better details in CaK band then?

No chance on that. I would have to come into some cash to hurry! :lol:

I think Baader makes a Venus filter too.

Would a 430nm reveal faculae any easier than a 540nm would? I know, I would'nt have to ask the question if I would just use the filter!! :lol:

James, just go with Antlia Wedge and their CaK filter, the more you keep waiting and thinking the less you buy anything or the further you will be from getting one.

No. All the filters yourself and Rainer linked to have bandpasses like 10x+ higher than the either the Antlia or the Altair. They just offer UV continuum views. Combining isn't going to reduce bandpass just light throughput.

Tareq, try your Astrodon UV in the antlia wedge and see what you get.

Mark,
That was an interesting blog you did on filter tests. Did you ever find a practical filter or combinations of filters past this that would do CaK features at a more affordable cost? That especially applies now that Lunt has sharply went up in cost on their CaK modules in the last year.

Do not buy the Baader U !!!! it cuts at 380nm so blocks CaK at 393nm. I have it and it does!!!

So, the best value choice here is that Antlia CaK filter then.

The filter alone is $269, but with the wedge is $339, so it means both the wedge and the filter are cheap, assume they are like $170 each, that is a steal really, and i am talking about those who don't have anything, even if they have a wedge like James did it is not a harm to have another wedge, otherwise he has to buy doubles and doubles of that to get something like Lunt or Quark Module for CaK, he already mentioned about budget limited, i had budget limited, and to him paying about $269 for a filter alone is not worth it, but with the wedge is a good idea, i told you i have 2" Continuum filter, i will buy another wedge for it.

Hello Tareq,
As a reminder, Antlia Ca K filter is not a Ca K filter, but a narrow band UV filter. This is a pitty Antlia perpetuates confusion.

Here is what you get with a narrow band UV filter (FWHM = 8.5 nm) :
http://astrosurf.com/viladrich/astro/so ... -Kline.jpg
Going down to 3 nm FWHM does not changes things dramatically.

On the other hand, Ca K filters have FWHM < 0.5 nm. This is why they are unfortunatly expensive :
http://astrosurf.com/viladrich/astro/so ... 63-Cak.jpg

I guess the difference is obvious.

Best price for a true Ca K filter is probably Lunt Ca K filter.

I understand easily the difference between the true CaK filters like the Lunt filter vs the wide band K-Line filters like Baader and Antlia sells. If I get one of these it would be for the second wedge for the AT72EDII and I would use the filter to view/image faculae across the disc. That’s something images show that it can do. It certainly doesn’t change my plans to get the more narrowband Lunt module when finances allow.

And I certainly encourage Tareq to use his and see what he can get out of it.

Hey, Tareq, the filter can be removed from the wedge, right?

James


P.S. Thanks for the advice everyone, especially Tareq, Mark and Christian.

Ok, we are going into circle here, i just said what i have, if someone can afford a true narrower band CaK then simply go with Lunt CaK and similar, if someone wants only something like a wide band in UV/K-Line and cheap price there are options such as this Antlia Wedge, if someone really doesn't like the result of that wide band K-Line then please forget about Antlia and Baader filters, can't be easier than that, and when i bought the Antlia i was dump and didn't know the difference, but now i am not regretting it as i like the result anyway, i already said i wasn't trying to match a true CaK, but it sounds here some are trying to just say "Please avoid Antlia/Baader K-Line and save more money and buy a true CaK even if it is more expensive", if that is the case then my job is done here and i won't sell or give up Antlia wedge and NUV filter.

I am sure it can be removed, how they placed it there anyway, but the problem is that removing it is not easy, as i can't open the wedge deep enough where i can put y fingers around the filter to screw to take it off, and i really didn't want to risk making the filter dirty or damage or screw up something trying to remove the filter wrong, so i left it as it is, but from what i see, it can be removed, maybe they used a tool to mount it there tight.

Alexandra mentioned in the past about the Baader K-Line filter making a good faculae viewer and I think the Antlia filter would do that well too and not only at the limb edges like the 540nm or WL image does but across the disc.

I may follow suit with this filter because of this fact, as a tool to study faculae!!

James

P.S. With ultra-narrowband CaK they are called " plage " just as in Ha because you are viewing more lower chromosphere vs more photosphere as in the wider bandwidth K-Line filters.

And i think with a longer focal length and slower focal ratio scopes it might be even better, we can't judge the filter and wedge from one or two or few users without using the filter in all settings or setup or conditions, i am sure if i bought Lunt CaK i won't produce an amazing contrast result with it as well, so later when i will use that filter more ad with another scopes then i can see what i get after all, i still have issues with focus and processing, and now i am ordering few items to help me in something.

Thanks Mark, Did you check out my post on the KSO? An opinion, whould you consider KSO updating every 10 seconds as " realtime " or does it have to be a live video feed from the scope? I would certainly consider a live video feed realtime and would teat it as if it were one of my own instruments. I could then capture and edit from the feed.

My primary use for KSO data is for CaK.

Imaging yes, viewing no! Even with imaging is not easy, the vast majority of the stuff out there is just over sharpened noise and post processing artefacts that manifest as granulation and faculae.

Hmm, it's an imaging only wedge anyway. I would have used a monitor for visual use anyway. I tend to be conservative on over sharpening to increase detail, that's probably one reason my images are a bit fuzzy.

If you're thinking of using the Antlia wedge as a 'live view' source I can guarantee what you see on screen is going to be lesser than what you get with a continuum filter in the same situation (on screen).

Lots of people have been here before with Baader K-line, Omega Bob filters, thorlabs stuff etc as a route to 'cheap CaK'- it's a road to nowhere! That's why people don't use it now and you don't see images from it.

Best way with this - keep looking on the classifieds /ebay / second hand market for Cak PSTs, not much more than a Antlia wedge - get one, mod it and get better results than with a Lunt CaK module. Patience and long game is the way forward! :)

I would need help with modding. I would not know where to start. I would certainly need your advice. A used Lunt module may be an option too, if I had the money at the time to buy it.

My guess is the B600 Lunt CaK module. $1,100 USD . Mark would probably know for sure.

That is the only thing i found, not cheap, if it was like $500-700 then we can think about affording one, but with this price, i think next year i can plan for it.
