Hi Robin and Ken - I posted this sketch http://www.cloudynights.com/photopost/data/500/11401sa-illum.jpg here on Dec 8 last which, to my knowledge, received no...
Hi Maurice, I remember commenting somewhere when this came up, perhaps in a different context. If you take a practical example of say an f10 scope and the...
hi, i read on website about heliospectroscopy with the slit spectro (Lhires.) i have some questions ? must we use for savety reasons also an filter in front...
Hi Dominique, The Star Analyser dispersion is very low compared with the LHIRES with a 2400 line grating. This means you must use a filter to view or image the...
Hello, I have had this quasar on my list since being inspired by Robin's observation on his website a couple of years ago but only now have I had a go myself. ...
Hi Rob, That is an excellent result. I like the way H alpha and beta show clearly in the image (Is that H gamma and perhaps even delta I can see in the graph ...
Could be of interest if you are far enough South. This one is 5 days after discovery and fading from a high of V mag 8.5 Robin AAVSO Special Notice #157 ...
This is now reported as a confirmed Nova (V1213 Cen) from a spectrum which showed H emission lines. It is currently V mag 10.5 so still within range of a Star...
I said it could be done ;-) http://www.iceinspace.com.au/forum/attachment.php?attachmentid=58009&d=1242567970 Congratulations to Terry B on the iceinspace...
While attending the joint AAVSO/SAS meeting in Big Bear CA I met Olivier Thizy. I was so impressed with the star analyzer, I bought one! My interest is...
Hi and welcome to the group, It sounds like you have an excellent location for an observatory. Here in the wettest corner of NW England we are lucky to get...
Thanks I will give it a look later. I was blown away by the high level science being done by back yard observatories! When I was a kid and the 6" reflector and...
I would like to send a mail to this group. Steve Please take time to visit my web site. Â http://www.btinternet.com/~stephen.durr/ I would like to send a mail...
Whoops think I made a mistake. Hello my name is Steve and I an interested in starting out with the star analyser, I am ordering one from Paton Hawksley in the...
Hello Steve and welcome to the group, I would recommend trying Vega first as it shows clear Hydrogen Balmer lines to practise focussing on and it is nice and...
I just received my Star Analyser and included with it was a CD labelled Star Analyser 100 User Manual. After inserting it in my laptop I could see that it was...
David, Explore the CD (it won't autorun): you should have a document file with the user documentation on it. Otherwise, the on-line manual is the same than the...
David, If you look the star Analyser, the glass on top is maintained by a locking ring. You should have a separate one in a small bag inside the main...
David, I just bought a SA100, the spacer ring was included in a small plastic self-seal bag. It's a very narrow ring about 28mm diamter and about 0.5mm wide....
Thanks for the description. Definitely no extra bag with the Star Analyser. I'll have to check with the dealer tomorrow. I also checked the CD and it is...
Hi David, you can find the user manual here, see: http://www.patonhawksley.co.uk/UserManual.htm As a temporary work around, you can remove and use a retaining...
... I actually found a way that will be better than using the locking ring for my purposes. Baader Planetarium makes a T adapter that is a quick release. This...
Hello Steve, the 8 inch SCT is probably your best bet. (Do you have a 0.6x focal reducer for it? That would help keep the star size small which helps...
I finally had a chance to image my first spectrum of Vega. I've had a quick look on the net for examples and it is close but I'm wondering what the dip is just...
Hi David, Congratulations on you first spectrum :-) The dip is at the overlap between the green and red channels and is almost certainly caused by the camera...
Thanks Robin for the comments. I suspected along with others comments that the sensor response was a factor. Your comments are very accurate in describing the...
If you are having problems with clouds or light summer nights at the moment, here is an alternative use for the Star Analyser. Just posted over on the German...
