    A quick midsummer session

    Hi Martin Very nice variety of objects. I really like the inverted view of the M64 and the ARP galaxies. Good to see how your new software is working along with SLL. It is still amazing to me how good views can be seen with no darks, flats, or no filters- just bad pixel removal. I know what you mean by the weather. I have now been out once in the past 3 months and more bad weather on the way. All the best with continued success using your new software. Bruce

    Hope Hilodon has not been affected by Volcano/equake

    Don is just fine. Chatted with him yesterday. I am sure he will be back online soon. Nice of you guys to ask.

    Well done Martin. These are always a challenge but a fun one at that and your new EAA tool seems to be coming along. Like Don, I think I have had about 3 nights over the past 3 months where I could actually see something. Continued success on the development of your tool. Bruce

    Multispectral Captures with StarlightLive and NB Filters

    Well, I can try v3.2 but doubt that is it if I am the only one having this problem. It is just so odd as it happens randomly at anytime during a single exposure or after multiple stacks. I did hear that Paul is around but too busy at work to address any SLL questions for now. I will just have to wait until he can re-engage unless I can figure this out or I need to find another software to do this more reliably.

    Jocular -- a new tool for EAA

    Best of luck in your endeavor, Martin. It sounds very exciting and all of us will benefit from it.

    Multispectral Captures with StarlightLive and NB Filters

    I'm following up on this topic as I noticed over time that I am now unable to get this to work. My first few times this worked flawlessly but then I noticed sporadic responses when I tried it again about a month ago, meaning the color of an individual channel would suddenly turn mono. I switched laptops and tried both the Windows and Mac versions of SLL and it worked at first so I assumed it was something on my Mac the was causing the problem. However,the same thing happened on another mac and my windows compute stick- the signal reverted to mono once again when it should have been in color. So, I am now down to the camera and cable and possible causes. I tried a different cable but of the same brand. I do not have another mono camera to test. I'm in no hurry to resolve this but am really perplexed as to what is causing this as it does not seem that either the cable or camera are likely the reason. Any ideas?

    Best 80mm refractor

    correct- but other factors can affect your exposure time as well (e.g., camera, light pollution, etc)

    Thanks, Rob. Very cool !!! Glad our M42 images look alike :-) Can't wait to keep exploring with this technique on my C11" with the hyperstar. Thanks for your input and initial help. Bruce

    From my C11" EdgeHD - most with hyperstar (f/2) and some at prime (f/10) using a SX UltraStar C camera.

    Best 80mm refractor

    I bought a Stellarvue 80mm APO triplet (f/6) several months ago to compliment my CPC 11" and could not be happier. However, I have not tried the others for comparison purposes. Getting an 80mm and adding a focal reducer (I use a MallinCam MFR-5 II focal reducer, 0.33x to achieve f/3.6) gives you two terrific FoV. Finding a good one second hand one might be a challenge but it will be worth the wait.

    Multispectral Captures with StarlightLive and NB Filters

    I finally got around to trying the NB filters on M42. These were taken on an 80mm APO Triplet (f/6) with an UltraStar M using SLL, v 3.3. Both images were taken using Baader H-alpa, O-III, and S-II NB filters, 3x20s per filter stacked. First image is using the Hubble Palette and the second is using the CFHT Palette.

    Multispectral Captures with StarlightLive and NB Filters

    Thank you all for your comments. Dave- thank for the info. I have both Baader and Astronomik filters so will try both and I just received my OIII and SII filters to try. Rob- I have both the M and C versions of the UltraStar and have dozens of Ha images with the M camera and some with the C- no problem doing those. I'm specifically interested in using the M camera to get the multi-color image that Martin displayed. Martin- thanks much for the description of the settings and images and help again, as always. - just so I am perfectly clear and a couple of more questions: "If you collect H-alpha with 'all' (in Exposure Channel Mask) checked, you get H-alpha on all channels and when you display it combined it appears as monochrome." --- UNDERSTOOD and have done this "If you collect with just 'red' selected, then when you 'combine' it it only contains information on the red logical channel, and so when examine it with the 'Display Selected' unchecked (this displays the combined channels), you will see a red signal as there is nothing in the G and B. ---UNDERSTOOD; this is what I was doing and getting everything red (which I think was my mistake) " if you were to look at your red-only signal with 'Red' checked and 'Display Selected' checked, you should see a mono signal. For maximum clarity, by 'red' selected, I mean 'red' in the 'Channel Selection' part of the 'Display Processing' pane, and not 'red' in the Exposure Control' pane..." --- have not tried this; QUESTION: when I check 'Display Selected' , do I leave 'Modify All 'and 'Auto Align' checked?? "And this is when combined (with 'Display Selected' unchecked)"---- THIS IS THE END RESULT I AM LOOKING FOR; SO GET THIS THIS THE FINAL SETTINGS ARE... Display Selected - unchecked (thus, 'Modify All' and 'Auto Align' are still checked)- correct? - I assume it does not matter which order I use the filters just as long I select the appropriate color selected when taking my exposures, e.g., 2x30s of each stacked Sorry for the additional questions. Thx much, Bruce
  13. Over a year ago, Dom 543 had started a step-by-step method to perform such captures with NB Ha, OIII, and SII filters using SLL and a Lodestar X2 both here and in CN. I tried this the other night using a Ha 7nm Baader filter on my 80mm APO triplet refractor scope and my UltraStar M for a 15 or 30s single exposure of M27. I aligned the Dumbbell Nebula and captured a very nice B&W Ha image. However, when I unchecked ALL under Exposure Channel Mask and checked only RED as suggested by Dom's procedure, the entire screen turned red, including the image, stars, and empty space. Even the signal peak on the graph was red instead of white. Dom's procedure for M27 started with the OIII filter followed by the Ha filter but I did not have an OIII filter to follow his procedure exactly. Besides, I do not see why that would make a difference. Any ideas as to what is causing this all red image I am getting?

    Some colour issues with SLL 3.3

    Hi Don I have had the defective pixel removal tool enabled but always create a set of darks before I begin. Should I not be doing both? I really have not noticed any big issue in doing so but is it best not to do both? Hi Roel/Jim I also get the reddish halo around some stars- the use of filters or not make no difference.

    M 17 and NGC 6618 open cluster

    Looks great.....but get rid of the check mark!!! It only causes a distraction from the great image you took
