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.

Re: Which mono camera for Lunt 50THa ?

Hi Hans, I use a PGR Grasshopper 3 (IMX252 chip) on my Lunt 50 and am very happy with it.

I was just looking at the 252 chip. It looks like a very tight fit for the Sun FOV at the LS80 native focal length.

I would like to hear if anybody has experience with newton's rings with this chip.
Newton rings are a problem with this chip but can be overcome, I use a "tilt adapter".

Re: Camera rec for Lunt 80

I was able to image through a friends 80mm single stack last month with a PG GS3-U3-32S4m, here are some images using a 3x tele-extender and a single shot full disc. I would point out that I am no expert and on the day the seeing was poor but if they are of any help. https://farm5.staticflickr.com/4...

Re: Help -Newbie with a LS50THa -Pressure tuning

Hi Andi, I have the same scope, when you unscrew the knob you are reducing any pressure so you don't hear a hiss or pop, when you screw the knob in you are starting from a point of equal air pressure in the chamber and outside. You will also find you will have to screw the knob in quite a way to tun...

Re: Lundt 35

Try a barlow, I had to do a few mods to my LS50 to get in far enough to focus, the barlow allowed me to get focus before this, but sadly could not get a single full disc shot.
