AR3288-3285 in white light with the Mewlon 250

[christian viladrich]

Hi,
The weather has been continiously very bad since February. Today, I had a short clearing between two clouds. This was the chance for a first light of the Mewlon 250 with an OIII filter.

Next try will be with the G-band filter.

Superb result

What are you using for filtering on the mewlon ?

Wow - it's like being in close orbit. Amazing.

[rigel123]

Amazing details!

[pupak]

Fantastic details.

[DeepSolar64]

WoW, Christian. This is the way the photosphere is supposed to look! Top-notch work. The granulation and spot detail is impressive. The Takahashi Mewlon 250 does VERY well. How do the Mewlons compare with Celestron's Edge HD Schmidt Cassegrains?

Two thumbs up and more!!

That looks to be working well Christian! Hope your conditions improve, mine are rubbish too at the moment.

Great image Christian, the new Mewlon seems to work well.

FANTASTIC image Christian.

Thanks to all :-)

I use a full aperture Astrosolar ND 3.8 and an Astronomik OIII 12 nm filter.

Nice interrior structure or bridging, thanks for the close look!

Sure Aaron, the faint light bridges and the umbral dots are quite interesting.

James, finally the Mewlon is doing good. I have the "old" version. The one without the coma corrector. So the diffraction limited field is very small. Still, it appears OK considering the field covered by the ASI290.
Collimation stability is quite good too. This is a nice surprise since I collimated it more than one year ago.
Compared to the Celestron's EdgeHD, the Mewlon has a smaller central obstruction (about 25% vs 33%) which gives some more contrast.

Considering that the current version of the Mewlon includes a coma corrector, this is certainly a good telescope for solar imaging. Still, much more expensive than the EdgeHD OTA.

I am planning to test it in G-band (430 nm) and also Ha.

Thanks Mark ! It was a rather short clearing. Forecast for the newt five days are bad again. This has been the worst year for solar observation since the last 10 years :-(

Thanks Denis. I hope to confirm this with Ha observation.

Fantastic image, Christian.

Christian,
Thanks for the info on the Mewlon. I look forward to your Gband and Ha images.

Sensationally sharp image Christian.

[Carbon60]

Superb, Christian. These are beautifully sharp and detailed images. Nothing less than expected from you The Mewlon is working well.

I hope your weather picks up soon to give you more opportunities than you’ve had over the past couple of months.

Thanks Denis. I hope to confirm this with Ha observation.

Im confident, this Mewlon sounds like a good and compact allround platform for solar images in different wavelengths.
But also interesting to see how well the astrosolar film works under more extreme magnifications.

[MAURITS]

Amazing WL images Christian.

Excellent work as always Christian

Simply perfection

That Mewlon delivers with this filter...I'd be curious to see how it works with others too!
