Re: Where is everyone headed ?

I am headed to Mitchell, Oregon. I saw my first total solar eclipse in February 1979 just 70 miles north or Mitchell in Maryhill, Washington. This will be my fifth total eclipse, having also seen them in Voi, Kenya 1980; Hula, Papua New Guinea 1984; and Todos Santos, Mexico in 1991. I am so excited,...

Beautiful images David! Could you describe what a 'plastic bag flat' is? How does this help your images? Thank you.

will an IR/cut filter help me?

I am trying to image the sun in WL using a standard DSLR and Nikon 600mm telephoto lens. I have experimented with a Baader ASTF white light solar filter, but (naturally) the results are not up to the quality of others I see on this forum. I have read that when using the Baader filter, adding their S...

Re: minor issue with imppg

Thank you very much GreatAttractor! I followed your instructions and now all is well. I changed the name of the file: imppg.ini to: imppg.ini.bak and that did the trick. Thanks again for the help!

minor issue with imppg

I have been using imppg, but suddenly I can no longer call up the tone curves tool. I un-installed it and re-installed the latest version but still no curves tool. When I click on its icon, there is a subtle 'blink' but then, nothing. Has anyone else had this issue? Any ideas how to correct it? Than...

Re: Advice for taking equipment on an areoplane

I defer to Stu's advice about transporting the hardware, but AA batteries are all the same the world over. Just buy them when (and wherever) you arrive. BTW, where are you planning to go?

Re: Do I have a Lunt lemon?

Thank you all for the suggestions. Mark, the allen bolt under the pressure tuner cap is tight. (likewise on the DSII). I wish I knew how Lunt was able to produce an acceptably sharp image with my scope, while I cannot. I am using a ZWO1600 which uses a relatively large sensor, but I cannot imagine t...

Re: Do I have a Lunt lemon?

They said it was a single image, not stacked. it is not as obvious in this image, but I do see the softness along the limb at the bottom of the frame. My image from today was processed with AS!2 AP set to 140 (if I remember correctly) usi...

Do I have a Lunt lemon?

I keep seeing other posters' FD images that are sharp and detailed from center to edge. I have been struggling with my Lunt LS100 for nearly a year and have never made a FD image with sharp detail around the solar limb. I have tried "clocking" the camera/blocking filter/etalon with no improvement. I...

Re: Another day, another problem

I have a similar issue with my LS100. Did the disassembly/reassembly help with your scope? How much disassembly is necessary? (I don't want to get so deep that I can't reassemble it)

Thanks for your advice.

Piggyback for Lunt LS100?

I want to piggyback a small camera onto my Lunt LS100. Does anyone know where I can get the proper clamshell ring that would accommodate such a rig? JMI makes some but I don't know if they are the right size. Thanks for any suggestions.

Re: SKY & SEA | ASTROPHOTOGRAPHY & UNDERWATER PHOTOGRAPHY EXHIBITION

Nice work Pedro. I assumed I was the only underwater photographer on the SolarChat forum. Of course it is usually unwise to assume anything. If you are interested, you can see some of my U/W work at: www.randallbenton.com

Beautiful work, and congratulations on the exhibit!

Re: Bedeviled by DS LS100

Images are similar when single stacked also, but the affect is less obvious. I use Autostakkert to stack the images. The good people at Lunt made the same suggestion as ERoel did, so I'll try that this weekend. Thanks for all the suggestions.

I am selling my 6mp PGR Grasshopper3. (GS3-U3-60QS6M-C) I bought it in May 2016 and used it about a dozen times, so it is still just like new. I think it may have been a bit too much camera for me as I am new to this hobby. I plan to replace it with a more modest model. I paid $2,800.00 USD, and I w...

Camera overheating

I am using a 6mp PGR Grasshopper3 and it often will overheat and shut down. I live in norther California and the temperatures can get into the high 90s. Of course this camera was probably not designed to work in the direct sunlight during the California summer heat. I contacted Point Grey, but they ...
