Basically the same technique. For similar spectra widths the distances will be the same, just need to modify the adaptors to give the required distance. I've...
Hi Alain If you definitely need the slit, how about moving to a fully collimated design which would be more compact and give a worthwhile improvement in...
Hello everybody, I'm looking for a spectroscopist to book and use together for two weeks a larger telescope located in a good site in order to take quasar and...

Is it a achromatic telescope, like Orion80 or 120 short tube (F5) a good option for spectroscopy and/or photometry? Or is it essential to get an APO for these...
I don't have yet any practice but I plan to use an Orion 100 for spectroscopy with a Lhires. In this aim, I have decided to use a 1200 grating. Olivier Thizy...
Luis, In spectroscopy, better to have a large optic than a good quality ones as you use the center of the optical path and your goal is to get as much photons...
Just a couple of extra points: If you are doing low resolution slitless spectroscopy with a wide wavelength range, (eg using a Star Analyser) then a reflector...
Thanks Patrick, Olivier and Robin. I have a star Analyser that fit in my Celestron11. For photometry, as my seeing is bad (6-10arcseconds) I would need a CCD...
whit this cam http://www.unibrain.com/Products/VisionImg/tSpec_Fire_i_BC.htm I am able to do binning maybe you can get the 20 you need jack 47'N 71'W Thanks...
Hi Luis, Getting the maximum resolution with the Star Analyser could be difficult with this setup. The long focal length of the C11, poor seeing and small CCD ...
Yes, with the Celestron I used two reducers together: 0.63 and 0.5, resulting 0.3, that it could be not to bad for spectroscopy but not satisfactory for...
I'm sorry, but I don't understand electronics. I have been looking this web page, and I don't know how to do a binning Luis ... in ... FOV ... quality ... get ...
it not electronic it is just the way to setup the cam it come whit the sofware of the cam you have less pixel in term of pixel you can go to 4.4.4. or 160x120 ...
Hello Again my ST7 is out of order. I don't know how long it will last. Therefore I am thinking of using my back up camera (an Atik 16) with my Lhires. The...
Hi Patrick, I use an ATK 16-IC with my LHIRES III which has the smaller but similar Sony ICX424AL CCD. The camera comes from the same designer as the ATK16 ...
Hi Robin Thank you for your encouraging message. I was very disappointed after the new failure my ST7. Then I will concentrate on my Atik. Do you think some...
Alain, N'oublie pas les softs derrière et de ce fait l'ouverture des drivers de la caméra qui permet d'utiliser tel ou tel soft au lieu d'un pauvre et unique...
