A Very good primer that.

I'll have a re read of it later.

The weird thing is, although it should not work, using the one image and converting it to individual channels also seems to work. Though not in all cases.

I agree Ha also works, i have imaged using that in place of the L filter as well :-)

There are only a few occasions when I have ordered bits from TH, but their service was very good I have to say. I used to love going to their shop when it was in London. Farringdon Road. I always was made to feeln at home, even though I never made a purchase.

I just gloated over the huge scopes on display and dreamt one day, one day, one day. "Hey, how much longer are you going to be"

Ron.

you know i used to go there often as a boy too. In fact i still remember 20 years ago being taken in there by my mother to purchase my first pair of binoculars. Carl Zeiss Jena 7 x 50 because Patrick Moore recommended that spec.

Does not seem like 20 years now, but i recall testing these and my mother buying them for my xmas. One of the best pressies ever, and yes i still have them in my brown leather case, and yes they are still very much in service.

ONe Caveat, only i use them no one else!

I do remember looking in awe at the giant meades, some of them at 13 years old (i am 36 now) used to virtually tower above me.

As with many here i always used to think "one day, one day"

Thank heavens i have a wife who supports such investments.

Since i met her 4 months ago, i've invested in a DSLR camera with all the trimmings, booked on two more star parties.

life is good

Telescope is very good service, a tad expensive i find, but very good service.

An excellent interesting read!

However, not wishing to hijack the thread, if you o back a page, you see this lot too!
