Re: 80mm Mod

Re: Full discs with LS50 and TS80ED

Do you use a tilt adapter or do Newton rings not pose a problem for you, I cannot get a uniform disc in a single shot I have to do mosaics.I will have to try rotating the diagonal.

Re: Today's Sun 26/06/18

Single stack, had a chance on Sunday to double stack and wasn't impressed, my disc shots are not even across (due to tilting) but were worse double stacked although the filaments were much better.

Re: Lunt or Quark?

Doing outreach I would go for the Lunt, waiting to come on band takes time with the quark, you are instantly observing with the Lunt.

Re: Televue or not.

I regularly use a 3x tele-extender and a 5x televue powermate and have no problems achieving focus through my Lunt 50 with my PGR camera, I have not tried visual with these as I use a Lunt zoom for visual. Hope this of some help.

Re: My first Scope and Problem!

Hi there, the lines are newton rings, it is a common problem with some easy fix's, you could try tilting the camera (my preferred method) or take flats, below is link to an excellent article for solar imaging.

G-Band filters

HI, I am thinking of having ago at g-band imaging and came across this https://www.thorlabs.com/thorproduct.cf ... r=FB430-10 at half the cost of the Edmund optics 430nm filter I wondered if it would be suitable, the spec seems the same but with that price difference it sows some doubt.
