Dennis, did you receive my in house contact details. And did you receive my email address. Both appear to me that they are not working.

Mark I’ve just succeeded in getting all to work, both SharpCap and FireCapture.The unpacking helped enormously. Prior to this I must have unpacked the FlyCapture folder because that achievement then meant that the two astro softwares could then work. So again thank you to Montana for first prepping ...

solarGain

The new FlyCapture download will not run on my mac mini. So thats the end of that I fear. By the way, I have already bought a Apple mac M2 setup so if I have to by a newer mac mini thats going to hurt. So are the FLIR cameras ‘difficult’ to maintain the software updates, which I now believe they are...

solarGain

The camera works with my existing FlyCapture. However FireCapture V 2.6 will download but there is no .exe file to trigger things. Plus I get an annoying notice “ Compressed (zipped) Folders. Please insert last disk of the Multi-Volume set and click OK to continue.” Almost everytime I action somethi...

solarGain

So maybe v2.6 will work with what I have at the moment. Ok.

solarGain

Thank you both for your help, Mark is the v2.6 on the FLIR site and under which heading Spiniker or the otherone I cannot remember.
I shall try later to day. Great.

solarGain

As of today my camera works successfully with FlyCapture 2.9.3.11 and with Genika 2.13.1.0 (no longer supported) however I would like the camera to work with other astronomy software. Both SharpCap 4.1 and FireCapture v.2.7 - the camera is not recognised? This is what I need some help with. I would ...

And now for the image , duh!

solarGain

Ok, I have too many variables, things are not locked down. I believe I can now lock down the two Pentax Takumar lenses. So this is the horizontal scan line shown on Genika. The line is at best focus without any sharpening involved. One variable is that I do not have fine control of the horizontal li...

solarGain

I was hoping that either way this line was in focus. The collimator is the 2nd piece that has been focused, possibly poorly. The lighting used was a fluorescent lamp so not a strong lighting force. I also thought that the horizontal scan would be right but the 'bloating' at both ends I didn't want t...

solarGain

I am still at the building and fine tuning stage of my SHG, a la thesmiths. So this is my first image. Camera - 1st focus, Collimator 2nd with Telescope 3rd focus. It is taken with the aid of a 50x50mm Holographic DG. And I am assuming at the1st Order. To my eye the top and the bottom is out of focu...

solarGain

Fantastic animation Banjo!
Just to say on my older Mac FFmpeg shows a malicious bug when using Virus Total.
Use with the usual cautions.

Well I had thought I had some luck on Saturday 30 March, but as soon as I had put up the CR-150 on my mount and fitted all the pieces. I knew it was hopeless. Meter blue confirmed as well.Even with the iris set at 50mm dia. I couldn't modify the conditions. The conditions were appalling here in cent...

solarGain

This from the same popular CR-150, aka the CR-6. This all prior to Bob’s useful info on shimming with 3.2mm spacers (Ca-K), they are on there way to me. 3 days in a row with the sun after nearly 4 weeks of poor no sun weather. The first two were very poor but today the seeing was steady and and occa...

GreatAttractor, we are at some 230m above sea level. Yes it was a 100mm William Optics. DeepSolar64, Ca-k wavelength. Nice shot for white light! Indeed everyone thank you for all your comments. I've set up late today, and have been testing out new configuration around a CR150 (nice scope), I can now...

Fourth attempt now to get my images in the right order and not to have duplications of the photos.

I do hope you like this from 2020. One or at most two days of very good seeing in all of four months. The weather was the worst in many years.

Rupert Hi. I had second thoughts about posting this, but it proves what was said "It is possible to increase the F/D by adding a spacer..."" I've given up on the idea of a f35 system many years ago, but if someone made such a system I might jump for it, but, I'm concentrating on Hires...

Peter Hi. Thank you very much for the details and the curve. In 2010, I was in deep discussions with Dave Groski for more than 3 years. I opted for the Clifton Horne’s SHS that appeared in a copy of Sky and Telescope, in October 1971. It was fully built, my documentation of the build was poor compar...

Excellent, I took the liberty to show the sharpest image from the middle of the run.

Very detailed workings being shown here Peter. I am slowly building my 2nd SHG. This one is a Littrow ala Fulvio Mete and I shall almost certainly use a 50mm x 50mm reflective holographic grating from Thorlabs. The extreme infraRed parameters for this grating collapse just beyond 825nm, so I must as...

Three image from a morning that began poorly, almost 90% cloud cover. At around 11.00 am it had all cleared and rapidly setup. GONG supplied the clues since Austria is covered in 100% cloud. So, every thing happened quickly and processing the images was a quick. So the order is from East to West I h...

Ok, that seems enough for me to be getting on with it, except that it is so hot and stuffy being indoors right now.
I may come back to you in the next few days if that is OK. And thank you.

I seem to have gone rather rusty over the use of photoshop in my weeks of layoff. It involves layers and blending etc. Montana posted this recently, I cannot remember where... and I would certainly Montana and layers.png hijack the post that it was found in if I begun a conversation. I wonder if you...

Thank you all for your much appreciated comments.
Lets hope there is more to come in the near future.

Nearly 7 weeks since my last presentation. Quickly processed since there was not much to do. I will later today, have a go on the layers. Captured by eye with the fibrils clearly seen.

It would be extremely useful to have a photo that shows this (enclosed and well sealed) housing. Over the years I have done many searches on the internet that bring up 'nothing'. A professional such as yourself has tried and tested this particular safeguard and I think this would be quite instructiv...

solarGain

Oh, what precautions to do you use to keep dust away from the face of your gratings? Or do you just dismantle and put back into box, face up.
I believe that Edmunds' allow bulb blowers to be used.
Any thoughts.
John

solarGain

Well, thank you for clearing up this last question up, and the additional short paper supports this.
John

solarGain

Joe much appreciated. Thank you for clearing up the lower efficiency. As regard the Rowland, ultimately want we want is a 'small' portion of the spectrum that revels Ha, Ca-K etc. Or is it too fiddly to reach these lines? Or is it something else. And secondly is astigmatism on a zerodur base still p...

Well I am again embarking on my second SHS/ SHG. This time its a Fluvio Mete Littrow imaging train layout. A ultra lightweight setup. And its linear. I have the rail, the two telescopes, FS-60 taking the incoming light and a ST80 taking the retroreflective grating that returns the light to a 3-port ...

This was just a reading of the graphs for Baader Blue and your new Astronomik filter.
Baader looks like say ~95% and the Astronomik ~97%. Or have I misunderstood something.
John

solarGain

By my reckoning the comparison between the two is at most 2% is that enough "oodles of light at longer focal ratios". Indeed I need all of this light but have nothing to compare with the Baader blue filter. More opportunities in front of the scope would be good to hear about this. Many tha...
