SolarChat!

Glad things are better with the new camera!

Good Shot! I'm impressed you've seen the sun, the weather has been absolutely pants just a bit up the road.

Re: SUN 8/12/2015 Good results Peter!

Good results Peter!

A great full disk Eric!

That really is an excellent best of, best viewed full size.

Good shot Rich! You can tell it's a low sun with that wobbly edge.

Good results! ImPPG is far superior to wavelets, you should definitely give it a go.

Re: Full Disc White Light 02/12/15 + Data Good results for a mighty quiet sun!

Good results for a mighty quiet sun!

Nice results Michael! Have you tried stopping the aperture back a bit with the CaK full disks yet?

Yeah, the tiff straight out of avistack would be great thanks

Any chance of a completely unprocessed version of one of the shots with the 174?

The telecentric just unscrews off the back...

I'd sell it while you still can, although admittedly the value is going to be low. I'm in the same position with my DMK31.

Nice results there Mike!

Good results for the conditions Valery!

Looking lovely there Derek

Re: December 8, 2015: three quick disks A good result there Michael!

A good result there Michael!

Better than nothing mate! (and i'm on nothing at the moment!

)

A new toy - woohoo! I would like to get a double stacked 60mm unit at some point.

A lovely start to the day

Looks like a northern hemisphere to me...

Lots of people use the 174mm for solar with great success.

A dichroic mirror would be good indeed, I agree

Nice set of images Brian, especially through the fog. Hope the eye surgery goes OK.

That is good news!

Super shots Eric!

PS when browsing earlier time lapses of WL sunspots I'm often correct in guessing which solar hemisphere the sunspot was at. Often there's a subtle rotating of the penumbral area. Can this be related to coriolis forces just like we see on earth and it's atmosphere? An interesting idea! I can see ho...

That's a nice re-work Michael!

Re: Full Disc White Light 01/12/15 + Data You were lucky to get that Richard!

You were lucky to get that Richard!

Getting the full disk on the chip in one go is my favourite route, once it is all stacked it is even across the whole disk then.

Next step is getting the post processing cranked back a bit to reduce the image noise

Nice shots! It's way easier to stitch the Ha than the CaK without a seam or seeing playing havoc.

Looks posh! I look forward to hearing how you get on

Re: December 06, 2015..Images in H-alpha Good images Peter!

Good images Peter!

Excellent images Derek, more cr@p weather here in the UK today, thanks for these for

Way cool shots Pedro! That drone looks fun too

Absolutely mesmerising Theo! A very interesting processing technique.

Was this with the 6" scope or the C9.25?

Probably just best to buy a new one then, but from ebay not Daystar

Sounds to me like it should go back to Daystar for a replacement.

These work well. Keeping heat out of the tube is most definitely the way forward.

Good collection of images there Derek!

Looks good! No idea why....

Much better Bill.

You do have to have a decent cable with the Quark from the battery pack, I tried several that didn't work. I ended up using a 20AWG cable as this offers lower resistance than 'thinner' gauge cables. Have you tried the battery pack with other devices, eg to charge your cell phone to ascertain whether...

I now have my 152mm refractor Valery & the Baader full D-ERF, would it be possible to use my full D-ERF with my C8 as well somehow ? If it's possible I know I would have to reduce the end diameter of the C8 tube so I can fix the filter cell to it but is it possible ? You could put the 5" D...

Re: SUN 4/12/2015 Nice shot Peter, you did well to get some blue sky.

Nice shot Peter, you did well to get some blue sky.

Re: Solar activity in H-alpha. December 04, 2015 Nice images Peter!

Nice images Peter!

Sexy time!

Do you have a transmission curve?

Personally I think its a bit of a pointless product. Calcium is not the easiest thing because your eyes just don't work that well at those wavelengths plus long term exposure to sub 400nm can't be that good for your eyes. A 5A bandpass is also not exactly difficult to achieve with just a regular di...

That's an interesting link Ewan, thanks for that. It all ties in with decisions i've been making at the moment myself. In terms of (Ha) scopes I own myself I have my trusty double stacked 40mm Coronado which I can use I estimate >95% of the time throughout the the year. 12 months ago I got the ED80 ...
