  1. Hi yes it was captured with the Canon 1100d (with 2,5 barlow). I capture with EOS Movrec on the laptop and its *5 digital zoom. The settings in Movrec were set to ISO400 and 1/8th speed if I recall. The avi was processed in Registax 6
  2. Hi that was a long time since I had decent conditions (but just good tonight, still waiting for the great night). C8 with 2,5 barlow, canon EOS1100d, 1500 frames. Enjoy

  6. Nice start! Consider a focal reducer if you intend more dso. Did you use all your subs or selected only good ones? With my avx with c8 and dslr and unguided at f6.3, i prefer to take 60 sec to insure staking everything. I could go longer, but in case polar alignenment is not near perfect then it would trail a bit. Also consider to run a pec training if you have not done it for unguided (i do it manually, at f25 using a barlow, with liview at max magnification, it is very precise, using al 's reticle on the laptop screen) Then it is pint point sharp for 60 sec sub (running some pic just after the training, i could take 2min sub at f 25 over the full worm period, my residual error is about + or -3 i would say). Keep in mind to have well balanced mount (slight east heavy), park the mount at the end,and to avoid changing set up too much (in my case this influence how the pec can be reused and well valid, if you don t want to remake the pec training too often)
  7. Hi http://stargazerslounge.com/gallery/album/2295-first-images-skymax-102-dslr/ All taken with a skymax 102 on altaz with unmodded caon 1100d (with gso 2,5 barlow for planetary). Processed with pipp/registax for planets and nebulosity for deep sky
  8. I tried both imageplus and pixinsight in parallel. I would say similar results can be achieved. But i finally went for buying pixinsight as i found the interface better to work with together with all its processes -still many i am not using- (it takes sometime to get used to it, more than imageplus, but once you get a grip on pixinsight, it really a wonder.). Also i get a better understanding on parameters to play with in pixinsight than in imageplus Note that before going into this, i did use nebulosity for quite sometimes and it gave me full satisfaction on all its features (but once using Neb to almost its full capabilities, you want more, hence i went to consider above 2 options). And before Neb, i started with dss. So i think it depends clearly your level. I think my step process starting with dss, then nebulosity and now pixinsight has helped me to understand and progress (i guess you could start directly with pixinsight, but if you are a complete newbye, it is certainly overshoot starting with PI). And first of all, you need good sub (no need of PI if you are still in a stage of learning getting good subs)
  9. Hi, indeed I never realized also color banding is coming out: by curiosity, I just reprocessed another AVI (but the same this time -I don´t keep much AVI and don ´t have the ones related to the pictures I posted before) and indeed it is coming out (below exactly same original AVI, again with/without PIPP "Stretch histogram" checked, nothing else in touching colors, below is a stack in R6 with just a quick wavelet):... so further room for improvement for sure
  10. A 1st year in the hobby for me to celebrate: below results: 1) with a skymax 102 Alt/Az, goto, with a unmodded DSLR at prime focus. ISO3200, mutliple short subs of 15-25 sec at 3200 ISO, process in Neb3 (yes... you read right: it is possible to image some deepsky with a slow small aperture scope like a MAK 102 on an alt Az mount, believe it -of course limited to few bright object and quite some files to process -and to reject-, but possible): Orion and M5 (about 20 minutes and 5 minutes in total respectively) 2) with a C8/AVX, DSLR at f6.3. Mosaic of M81 (4 hrs) + 82 (2 hrs)
  11. Also celebrating my 1 st year in the hobby. All below taken with Skymax 102 Alt Az. Canon EOS1100d + 2,5 Barlow. Capture on laptop with EOS Movrec with digital zoom. Process in Registax.
  12. Thanks Snakey. Seeing on the 2sd one was a bit better if I recall (but the original color is always the same in my set up) Christoffer: as mentioned give it a try in PIPP from the starting AVI with this option tickled (this is not a pre-set to have it tickled). I am curious to see if that adress also the color issue with that simple trick in your case (as mentioned, in my case this was from a DSLR and I have no experience with your type of cameras, so may not work in your case?). I only process my avi´s with PIPP + Registax. I tried several time AS2 (with or without PIPP pre-treatment), but I never managed to get something better than PIPP + registax (maybe simply a matter of skill and experience manipulating AS2! some other certainly master AS2 better than I do)
  13. Hi To adress the color: before registax, try out PIPP and check the option 'stretch histogram' in some of the processing tab. In my case using a dslr, my starting color are about the same as yours. After pre-treatment in pipp, the more typical color came up. Don t ask me why, but this option in pipp was the solution to me (and without playing with rgb align in registax) Without the pipp strecth option: http://stargazerslounge.com/gallery/image/18103-saturn-4th/ With (from a different capture, but all the same set up and no other kind of color treatment, apart pipp stretch histogram): http://stargazerslounge.com/gallery/image/18145-saturn/
  14. Well done, you will not regret it! Check up collimation when you are 1st out if it needs to be adjusted after transport (pretty straightforward to collimate) -in my case it was required when I received it, I was a bit disappointed after my 1st views (but of course I was too excited to try it out that I simply I forgot checking the collimation which was slightly off on my 1st trial -but then corrected, it turned to stand 6 months without need at all any further adjustment. Also don´t forget to let it cool 1-2 hours. 2 basic SCT issues to have in mind to get the best out of it for best planetary views.
  15. Hi I have the little brother Skymax 102 (AltAZ go to). I Love it both visual planetary and imaging planets (and in case seeing is not that great -which is basically most of the time, it performs basically not much less than the C8 for planets as the skymax is simpler, lighter, more compact, no maintenance at all -never needed to collimate the skymax and pint point sharp always-). And as mentioned in bad seeing, no really big differences on the planets between the 2. This was my 1 st scope which pull me me into the hobby (to go into buying the C8 for example and maybe later on I will go for an APO) and will ever leave it for sure!
  16. Hi! I have a C8 for 8 months and already did a collimation when i received it (slight correction was needed, not much). Tonight i checked it up at *250 8 mm EP, slightly defocuse, could see it being again slightly off (i hardly see it at *100, only after indeed realized it was off looking at *250). I did not push using my barlow as anyhow seeing was not that good and the ota was not cool enough. Now it sems next week may be great conditions (best i think since i have the C8): clear skies, low temp, low humidity, no wind, no jetstream,....the moon, jupiter and mars are awaiting!!! (i think i will take my chance to get up early one morning to see mars for the 1st time) and hopefullymy best images (i use a dslr + 2,5 barlow, it works great). My question is related to the method to get best collimation: would it be at the highest magnification i can through the eye piece (* 625 with the 8 mm ep + barlow if seeing permits or at least at*250 with the 8 mm EP) or would it be using dslr/liveview on laptop (using live view digital zoom + 2,5 barlow and using al's collimation tool is pretty good and convenient and i did use that way successfully in the past). The main issue i can see is that with the laptop, the mag is roughly *190 at max in my set up (the liveview zoom *5 or*200 help furthe, but of course remains purely 'digital' mag, not bringing up sensitivity) I like the laptop approach as it avoids running around to the EP (especially that i do the collimation visually without diagonal, as i could notice my diagonal induce miscollimation - i have 2 basic diagonal of same design and both give me different patterns , , even at low mag, one is better than the other but still bring some error (same error using different EP). A good diagonal is on my coming purchase list). Also without diagonal, this way also corresponds better to my imaging set up, more critical/sensitive to misscollimation. I would think it may be more accurate and robust to go visual and highest magnification possible 250 or even higher) rather than being limited to my max imaging magnification (190) for collimation. Also beside collimation, that will give me the occasion to look more on optic quality looking at diffraction pattern at higher mag (i have not been fully satisfied with my planetary images with the C8 as compared to my little wonderful mak102 so i suspect some other issues like spherical aberrations or other). Even collimated and decent conditions, cooled ota etc i sometimes have difficulties to get easily sharp focus on the moon for examples (i never managed to get as good close up pictures of the moon with the C8 as with the little mak (see my galleries with the mak and what i managed on saturn the moon close up but this was good to excellent seeing i have not had chance so far to get with the C8... Hopefully i will know next week!). As another topic, i may simply have an almost 'perfect' mak102 and a low average c8 quality? Input welcome, so i go for working out directly the best way possible to finetune my collimation and not wasting my time in experimentation of collimation set up methods (personnaly this is not the part i have funwith in the hobby, i prefer enjoying watching or imaging than tweaking my equipment!) Thanks for input!

  21. Hi thanks. In fact I manage to find a detailed description how the script workflow is (but too stupid I did not keep the link and I could not find it again). Anyhow, indeed this is slightly different than the tutorial I copied above for what I remember of reading it (and it was answering my questions and of course the script to generate the masters etc is done with all right calibrations required). I did some trials on different set up and found only very subtle differences anyhow
  22. Hi Still learning on pixinsight and I have some doubts on work flow: I want to use the batch processing script together with master bias/dark/flat (instead of individual bias/dark/flat, a matter of going a bit quicker). If one follow the tutorial http://pixinsight.com/tutorials/master-frames/en.html for making the masters, are they OK for use in the batch processing script as such or not? My issue is related to the master frame calibration: In above tutorial, you calibrate the flats both substrating the bias and the dark (but you don´t substract the bias to the dark). So if you use such master in the batch processing script, does it recognized 1) the master flat is already calibrated on bias/dark (or will the batch processing repeat the process again) 2) the bias is not substracted in the dark (and it will do it) ? Thanks for your help

  25. Hi A first mosaic with C8 at f 6.3 with canon EOS1100d unmodded, unguided. 1 min subs at 1600 ISO. 4 hours on M81 and 2 hours on M82, pre-processed, mosaic and post processing with Pixinsight. I am really happy of it, it was captured at the lowest, just over the city light pollution, I was not expecting able to get really out the data, but it went really well Regards David
