Sunspot combo

[mightymonoped]

This is a reduced and compressed version of today's solar twiddling. Took these around 10:00 ish

ED80 (+ Televue 2x Barlow), homemade Baader filter on undriven alt-az.

Each image is made from the best 50 of 480 frames (2 x 240 frame avi's per image)

Nice, must get the PST aimed at them if the clouds stay away.

I like that 8)

Did you use the regular Baader Solar Film ND-5 or the version intended for photography ND-3.8?

[geppetto]

Tony hope you don't mind but there is 24 hours between

yours and mine images of those spots so I've over layed them

to show how the combo has altered

Steve

Didn't know there were two types of solar filter stuff :?

Tony/Phil.

Thats a very interesting animation/image. I must get myself some of that Baader stuff.......

Steve,

Same question as Phil....

[mightymonoped]

Thanks All

Steve & Phil -

Nice animation (of course I don't mind) 8)

I used ND 5 film. I find this works an absolute treat with the ED80. Haven't got round trying the ND 3.8, though I would imagine it's very good. What I'd really like to do is get a Baader Herschel Wedge and use that with the ED80 ( a marriage made in heaven methinks )

Not only the sun spots but granulation too..

Nice image...

[FLO]

Gaz, Phil,

Baader do two versions of its Solar Film: ND5 and ND3.8.

ND3.8 is lower density and designed for solar projection and photography only.

If used Visually, serious eye damage will result!!!!

(I don't list it on FLO's site for fear of someone ordering the wrong one by mistake! But I can supply it)

[geppetto]

Thanks Steve

I'll pass on that, only a matter of time before I would forget

and blind myself :shock:

Sound sense in not advertising it 8)

[mightymonoped]

Yes, thanks Steve. You can never be too careful when it comes to solar work, one mistake is too many!

I get nervous doing visual (even though I go through a 'flight check' looking for pinpricks, loose connections etc) so much so that generally, the only time I ever look at sunspots is via a laptop (hence the interest in ND 3.8)
