First Solar Photo

[AndyThilo]

First ever processed shot, be gentle :). 

Equipment:

• Explore Scientific ED102 Carbon
• ASI 290MM
• Baader Solar Film
• Baader Continuum Filter
• HEQ5

Need to get a solar finder to help lining up as finding the sun was a PITA! Even with rough PA and slewing via Stellarium it took me 10mins to find it haha. Now to sort out settings and go hunting for prominences and learn to do composites.

Solar finder - 1 cm bore tube, maybe 20-30cm long (preferably black). Add an opaque red cap to one end. Attach in parallel to your OTA, with red end downwards. When red end glows, you're there (ish).

Alternatively use the 'spiral' tracking on the ascom panel....

Nice start.

No need to go hunting for proms as you will not see them in white light.

None at all? The video I watched showed you could expose for them by blowing out the sun and then combine with an exposed sun photo.

I’ll try spiral thanks, wondered what it was for 😂

That would have been in HA though.

Or possibly CaK?

Ah yes you’re right, he used a Quark Chromosphere. Is it possible to use a narrowband Ha filter to get a similar result? Along with the solar film of course.

Caution - Only those specifically made for Solar work = ££. and not those used at night!

Unfortunately not which is why solar imaging in HA costs an arm and a leg.

Figured as much lol. Something to save up for 😊

[Altocumulus]

Actually, make that two legs....

[AndyThilo]

If I wanted to do Ha, would this be more suitable than adding a Quark and rejection filter to my ES102?

Gets me closer (930mm vs 714mm) although I could always use my 294MC Pro to get full disk. It would be significantly cheaper as well.

A couple of folks on here using them if you do a search, similar to Quark with smaller etaoln

Excuse my ignorance, Etalon?

The bit that only passes the HA solar wavelength measured in angstroms , 1 angstrom = 1x10 billionth of a meter.
