The Solar Photosphere - 23rd July

[David Smith]

Better late than never, I hope! Still getting back on track after laptop failure earlier in the week. Collected a load of data yesterday morning but it was a bit of a grind as I was trying to find my way with different versions of software etc, etc. I was then out for the rest of the day helping my brother and sister in-law move house. So finally got around to processing this morning.

In other news, new toy! Probably explains the cloud this morning, sorry  

It's the 1.25" version, came up on ABS at a price I couldn't resist. It arrived on Tuesday and I had first light on Wednesday, unfortunately the laptop issue wiped all the data I collected in that session so yesterday was the "official" first light. Initial impressions are positive, visually I struggled to see any more than with the Baader film but for imaging I think this is going to be a good step up. I still need to figure out exactly where in my setup it fits but certainly for white light close-ups this seems to be the way to go (see below).

Back to yesterdays images

For the first time I stacked my white light full disk images in AS!2. Previously had issues getting them to stack but seems to work better in latest version of the software. I may process the same data through Registax 5.1 in a bit, just out of curiosity.

Close-ups were taken with the Lunt wedge / QHY5 / #56 green filter. I do not have a continuum filter (yet ). Second image is just a crop and slightly different process of the first (same base data).

Ca-K to follow

Excellent shots David, I'm delighted you've cured your laptop woes and are up and running again.  I like the kit picture too!   That's  a great solar wedge  you have   .

Nice looking disc and close up.

Nice one David, I saw a Lunt Herschel wedge for £75 on ABS... 

Btw which scope are you using for WL?

It's just a Skywatcher Evostar 120 achromatic but works well enough. I was surprised the wedge hadn't already been taken as I didn't see it until almost lunch time. They usually get snapped pretty sharpish.

great shots Dave and a cracking solar wedge, welcome to the wedgieside , you wont regret it mate.  charl.

Very nice set David. I am sure you will enjoy using the wedge.

Very glad you've got yourself a Wedge Dave, I'm sure you will see the difference particularly when you get some good seeing conditions.

Do you have a UHC filter you could use? That has a narrower bandwidth than just a green so is worth a go.

Great pics anyway !

Nice smooth images David, just catching up, been preoccupied the last couple of days.
