NIce limb image and prom. Agree with Astrophil about the fog, I noted it depends much on sky conditions and on how much the brightness has been increased to show the faintest parts of proms. In most cases I am able to correct the problem during processing, but not always, sometimes I have to accept ...

Beautiful time lapse and disc, much detailed!

Beautiful images, Brian, the CaK and the DS are particularly sharp.

Thanks Eric, Alexandra and Maurits for you kind words

Super animation, really spectacular!

Really good images indeed. I am using the same scope for my calcium images, it is very well corrected for calcium imaging.

Thanks to all you for your kind comments

Great images, Eric, and beautiful Moon, very well processed!

Not much stuff to see today, however a nice filament and an associated plage area was visible in NE quadrant of the Sun. It looked prominent in my Quark Chromosphere so I decided to take an image through my Lunt-modified scope replacing the Lunt BF with the Quark. Between the PT module and the Quark...

That scope is no good for CaK at full aperture, it is too much aberrated at short wavelengths. Stop it down to 40-50 mm, you should note a marked improvement in definition.

Nice images, Marty, detailed and well processed

Great and even images, Mark, and interesting experience too. Thanks for sharing.

Wonderful sketch, very nice !

Great images, Stu, the FD is superb!

Nice images, Pedro, AR12733 has grown considerably in these last few days.

Nice images, David.

Thank you all, I'm glad you liked the images

Thanks to you all. I have been very pleased to note that the ES 3x behaves in about the same way as my Powermate 2.5x do, it provides a quite large sweet spot in my Quark which means it is almost telecentric and is very fine in Ca light.

The sky has been clear for several weeks during December and January but high northern winds due to a low pressure area stably placed on east Europe made the seeing always terrible and I had no opportunities to obtain any decent image. Last Sunday I couldn't resist to try my new Andover G band filte...

Very good images Stu. Have you used the 125mm at full aperture ? It seems well corrected in CaK....

I normally use a Baader CC with my 150 mm f/5 refractor without problems. Inside the wedge there are ND3.0 + ND06 filters. Someone adds a UV/IR cut before or after the wedge, I am not sure it is necessary.

Fantastic images! Which instrument have you used for the comet ?

As far as contrast and definition are concerned, yes, with an external amplifier my Quark works better than in the original configuration, not a huge difference but is there, in particular if an external or internal ERF is placed in front of the device. Actually this is the reason that lead me to re...

Great images Brian. I see some horizontal lines crossing the discs is WL and CaK... or is it my monitor ?

Very, very beautiful discs Alexandra. I understand that you images are with N up and E left ?
