Re: Processing issues. What next?

From your first post it sounds like you are trying to open the avi in imPPG. As far as I can tell imPPG only works on images, not video. You should stack in AutoStakkert to produce an image (TIF or PNG or FIT) that you would then open in imPPG. There are others here with a ton more experience than I...

Looks great! With my weather recently, any images I took I would work as flats :-(

Re: Powermate x 4/5 with a zwo 120mm camera

The PowerMates provide the stated magnification at the top of the eyepiece holder, I measure it at 52mm. You get less magnification closer, more further. The PowerMate has a 1.25" eyepiece holder on top, you can simply screw one on to the camera and plop it in there. I get Newton rings with pretty m...

Re: Yay! Finally something to image!

Thanks for the comments! The extra aperture and focal length definitely make a difference! The Quark also works pretty decently, didn't have to do much other than tweak the contrast and a light touch of sharpening.

Yay! Finally something to image!

Winds died down and the haze lightened up a little, so I had a go with the Quark and an APM HerschelPrizm in the WO FLT132. The APM seems to work quite well in this scope. Clear skies all!

Flats for full/partial disk

Hi all, I've been experimenting with masking off the sky background in Photoshop in order to get partial flat frames to work for full or partial disk images. Basically I create a layer mask on the partial flat, using a histogram stretched copy of the flat itself. This allows me to reveal an underlyi...

Re: h-alpha flat box?

The bag / glass / defocus flats don't work well for full-disk images, or if the solar limb is in the frame. Works OK if the disk completely covers the sensor.

Hi all! Looking to build an h-alpha system on my LX200 and am looking for a Daystar Quark Combo. Please let me know if you've got one gathering dust somewhere.

Thanks!

h-alpha flat box?

Hi, Has anyone tried building an h-alpha flat box using 656nm LEDs for illumination? I'm thinking of something like these. They are quite inexpensive but I'm not sure how many of them one would need to be sufficiently bright to be usable for flats. I'm sure it would be an easy project for someone wi...

Re: First try at a big mosaic and an animation

Hi Alexandra, Thanks for the suggestions! I have not been using gamma, so I might fiddle with that a little bit and see if I can find a more optimal setting. In the meantime, using a layer mask on a sharpened copy and overlaying it on the unsharpened layer seems to work pretty well and is not too di...

Re: First try at a big mosaic and an animation

Fantastic images!! Use ImPPG for sharpening and then use it to align an image sequence for an animation. I have some helpful instructions here https://solarnutcase.livejournal.com/18572.html There are many reasons why the mosaic software won't work but getting the right pictures to input is key. Al...

Re: First try at a big mosaic and an animation

Hi all, thanks for the suggestions! I will give imagePPG and AutoStitch a go. Re: the clipping, I noticed that as well and may have a go at reprocessing the frames; I'm struggling with how to sharpen the prominences adequately without inducing blob artifacts in the glow above the surface.

First try at a big mosaic and an animation

Seeing was surprisingly pretty good yesterday (12/12) mid-morning, so I had a go at a 6 panel mosaic and an animation. My alignment is never that good in the daytime, so I used LuSol Guide with a little 50mm guidescope on top of the LS 80 DS, works great! I'm pretty pleased with the result, but then...

Re: My first Scope and Problem!

I had one of those first, however not quite as easy to adjust when the camera (ASI1600) is mounted. I think the Daystar has more tilt as well - the 1600 needs a lot :-/

It worked fine for the QHY5III 174, though.

Re: My first Scope and Problem!

Hi, Welcome to the wonderful world of Newton rings! The bands are an interference pattern produced by internal reflections, often off the camera glass. You will really only see this when imaging narrowband like Ha. I have them very pronounced with Barlows, especially with the ASI1600MM. The most com...
