  1. Hi all, i need a little help here.... im trying to process the Cave nebula complex...its wide field, Reduced FSQ106, QSI 583.. i know the data is good..and im not an expert but neither am i a novice but im really struggling to get this subject right... ive tried Pixel math in various combinations...ive tried Images plus...ive tried PS and Hue saturation and clipping masks but i just cannot get the seperation of O111 Sii and HA correct.... or lets say as i want it!! is this target just plain difficult or what!!...i have 12 x 20mins of HA and 30 odd each of Sii and O111all 20min subs...enough i would have thought... any suggestions would be appreiciated but please please dot tell me to get more data...im fed up now....lol!!! Ray
  2. Hi all, indeed it was so easy to convert, I had some 2 years ago tried a brief foray into using my qhy5Lii on the QSI but abandoned it.....why oh why did I do that? The Caméra was actually very close to focus and with the longer fl....Tak reduced to F/3.8...it has improved the accuracy of my guiding.... the out of focus Lum filter is still used for auto focus and SGpro allows me to pause guiding during focus routines! Ray
  3. Thanks all for the replies...it is correct to say the prism is in front of the filters, however; when the filter is changed, the focuser offset means that the focuser May travel in...or out...and it’s thisaspect that changes the guide scope focus! ive fitted it for a trial tonight...I’ll set it up when thescope is infocus for the ha filter, the Astrodons I have are not perfectly par focal, but close enough...it’s the Lum filter that I use for focusing that might be the issue.....if focus is out by a good margin on the lum, it won’t matter...but yes...I agree...pause guiding during auto focus...if it actually works in sgpro!,, thanks again all Ray
  4. Hello all, can I ask if anyone uses a Qsi wsg camera off axis? ive had my 583 for years and always used a guide scope...I’m considering putting my qhy 5Lii mono in the guide port but I’m wondering how my filters will effect focus when I change between narrow band and lum for focus routines anyone knowledge of this? Ray
  5. I’m very glad you did know this one..lol...and thanks for replying. Ray
  6. Hi all, I’m helping a friend out tomorrow with her EQ3 pro, she wants t guide with it...o.k. No worries....limitations with this mount but it’s a start! so..my question is can the EQ3 pro use the eqdirect cable......??......I can lend her my ftdi cable is it can. Ray
  7. Hi all, been a while since I’ve posted! Ive not done much imaging lately, the weather for me has been the biggest hurdle, however; I’m of to Spain for a few weeks in February and I plan to take a Coronado PST and a tripod... i plan to use my guide camera the QHY5-Lii mono for imaging and a 4x Barlow... I’ve not done much solar imaging so I need a little advise on the kit I’m planning to use...i.e. is it good enough, is f40 going to get me close up (I’m assuming it will) what software would you recommend and what frame rate is achievable? i have an opportunity to purchase used Imaging source DMK 21AU618.AS MONO camera.....would this be better than the qhy5-Lii? Ray
  8. It’s a great idea in principle, I’ve been doin* it for some time, however in the uk; it’s really fraught with difficult our weather doesn’t lend self to long subs, our average seeing is pants due to the moisture that lingers so good conditions are rare. but...it is worth it and I’ll continue to do it, you just have to have patience and don’t get eager to accept subs that just aren’t good enough because they are long. thats a great sub and well done. Ray
  9. I have just completed a 4 pane mosaic with friend and we found it very difficult, in mainly due to the uneven background, so the 1s answer to the question is to try, insofar as you can to balance the backgrounds of the two halfs. the next thing is to try and separate the stars from the nebula or whatever is in your image...pixinsight does this well and so does Stratton software. but then you have to recombine...not easy to do. but the short answer to the question you ask is: for us, we used pixinsight, Stratton, photoshop CS5/6 and Images pus software..
