The Lunt Adapter for LS50/60FHa to LS50THa is a specific adapter to allow you to fit the LS50 or LS60FHa front mounted Etalons onto the smaller M80 thread of the LS50THa telescope. Although there is a dedicated double stack filter for the LS50THa, this uses a simple hinge to effect tuning. This mov...

Great job! I really liked the images in Ha! Maybe I'm wrong, is your name Nigella? That's just the nickname Nigella had. I'm sorry if I made a mistake.

Very nice image Ivan. Congratulations on the new set up. I am impressed you can get 7ms Exposures with low gain using the etalons. Does that require removing any filters in them? Hi, David! Thanks for your feedback, I did not remove any filters, although it was possible to remove the red erf before...

Thank you, Petrus and Stardust! I used two Lunt50 pressure tuners, which are supplied one after the other. This pair works well on telescopes with a larger aperture.

Hello everyone After a long winter, a small photo for my new setup. This is the Lunt50 triple stack. A mosaic of 4 panels. I have to do the mosaic because the spot of the second inner etalon is quite small. I hope you enjoy it. https://live.staticflickr.com/65535/53660565805_26c2792ac6_o.jpg 17.04.2...

Ivan

Ivan, I am so glad to hear from you. I hope you and family, especially little Regina is ok. Living in Russia would be hard on me, I am not a winter person. The long winter nights, cold weather and all that snow would have me in a down mood. I feel for you. I bet you really look forward to summer! T...

Alexandra, your photos are excellent, this filter just works wonders. One of your photos, which you took with his help in France, is stored on my desktop as a reference. :bow :bow :bow Transit looks both majestic and ominous at the same time.

Nice work Ivan. You are a Mosaic Master! I bet you dread winter every year. James Thank you, James! I don't like winter, it's just a horror for me. Low clouds, snow, ice, cold, darkness, narrow roads, because snow is not removed, but only raked to the side of the road. And you also need to dress wa...
