  1. Would narrow-band M1 work ? If so would a ~100MB zip via sendspace be ok ?
  2. Hi Zakalwe, You have an excellent first M42. Be very patient with your processing skills....it just takes time Your are off to an excellent start. Enjoy,
  3. Have you tried using a recent dark ?....might be better than no dark How many subs do you have ?....Using a median combine with high and low range rejection should clean most of the outliers....with enough subs Looks like some really good stuff is in there. I think the juice will be worth the squeeze.
  4. You might be pushing for a black background at the expense of the nebulous detail...could just be the JPEG (evil format) compression. You might consider extracting each color channel and working them separately. This will usually allow better control of the faint detail present in each color frame. A larger image with max JPEG quality would help the examination
  5. Tips, criticism, ideas, harsh language, dirty looks, et.al. are always welcome and always appreciated Excellent tip. Unfortunately, my PosAng is usually governed by guide star position. Ahhh....So always keep an eye on how you want the final framing ? I was thinking of a DSS image, NASA Sky View or the like, as the reference frame and using the star alignment tools in PixInsight to build each mosaic frame. Sound like a plan ? Thanks, Rusty.
  6. Okaaay....had you down for the 32" RCOS.... I'll make a note... "Kevin prefers SK 200P HEQ6 over RCOS."...check
  7. Some stuff on my list of useful things.... Sheet filters in different colors If typical red acetate filters don't work for you....everybody is slightly color blind in one form or another...or your computer monitor just doesn't get on with a given shade of red... "Gel" color filters used in theatrical lighting are an excellent option. Your local community/high school/college theatre can usually spare a sheet or two. Rosco has a large color selection. Gaff Tape : Like Duct Tape but cloth backed and won't leave a sticky mess behind when removed. Black for obvious reasons. White for labeling big,
  8. So.....Who is member 10,000 ?....and.... Do I have'ta get gifts for everybody ?
  9. Good point. Bearing and other mechanical slop can be a killer. Should the use of two cylinders mounted in opposition (pushing against each other slightly) be considered ? This would "pre-load" the compression and mechanical slop. An opposing gas shock (from a car hatch back, say) might be better...cheaper, simpler. Divide an Conquer. Always a sound strategy. Be bold and mighty forces will come to your aid. On parts and such...... I live in Dallas and work from home for a company based in Las Vegas (we also have a shop outside London). We do all our manufacturing in Vegas where we have a mach
  10. Nick....I love you, man. Most see things in the exact opposite way. When there are many variables that should be considered....the number is always higher than you think....The usual approach is to try and reduce the variables considered and solve the reduced set. While this is perceived as simplifying the problem. In reality the excluded variables still exist and will bring complexities that can seldom be resolved. Your super-simple method is vastly superior terms of results and violently more simple in implementation. The geek name for Nick's super-simple approach is: Closed-Loop. Warning: G
  11. Dude ! Really nice. Rich and Smooooth....... My wife had a look and wandered off mumbling something about needing chocolate. Ha is awesome. More please.
  12. EQMOSAIC looks like it will do the trick quite nicely Thanks Guys/Girls/Other your the best, Rusty.
  13. Hi Nick, I think your onto a Great Idea. The motion would be smooth, accurate and backlash free…like butter. (I love Hydraulics....one of my favorite methods for moving stuff.) Here is a bit of what I know of hydraulics and controls*. Ramble Warning: I'm just going to brain dump. You might want to leave now. Most of these notes go to "controllability" where many small errors can accumulate...often resulting in "uncontrollability" i.e. Tracking errors. - Fluids are incompressible....mostly. Hydraulic fluid will have ~2-3% entrained air that will give cylinders a very small bit of "softn
  14. Very nice indeed. Dust lane detail is awesome ! More please, Rusty.
  15. FTP is just fine, data size is a non-issue and when it comes to astrophotography stuff.....I've always got time Rusty.
  16. This is a first. People call me Randy* all the time....comes with the territory. But I've never had it happen in text. Free beverage of choice for Martin Thanks for the kind words, Rusty. *I know what some of you are thinking, mostly those from a small island...stop it. Silly person.
  17. I'd be interested in how it works out for you. I'm not using GIMP very much right now, but knowledge is life Rusty.
  18. Hi, I took the liberty of extracting the RGB channels from your file Autosave_02_with_flats.tif and having a poke around... Here are the statistics, normalized [0..1], for each channel: _____________Red_______Green_____Blue_______ Mean......: 0.3235641 0.3241946 0.3241418 Median....: 0.3184558 0.3181811 0.3180591 AvgDev....: 0.0218235 0.0223919 0.0222751 StdDev....: 0.0464170 0.0491118 0.0487883 Variance..: 0.0021545 0.0024120 0.0023803 Minimum...: 0.0010529 0.0010529 0.0010529 MinPos....: 00348,000 00348,000 00348,000 Maximum...: 0.9961089 0.9961089 0.9961089 MaxPos...
  19. Hi Martin, Really nice mix. I think the spikes look great, easy to over do it, you got it just right for my tastes. The Ha detail is also particularly impressive. Very nice work, Rusty. Ps. Ive got the beginnings of a narrow-band Jelly mosaic. Let me know if you'd be interested in a collaboration.
  20. Hi Pibbles, The bad news.... I get the same error messages. Looks like Gimp does not open RAW files (like you, I thought it did...grrr). The good news.... I did some poking around and the UFRaw GIMP plug-in gets the most press. You can find it here: UFRaw - Download & Install I installed it and worked like a charm on one of my CR2s. I'm running Win7Pro x64 and GIMP 2.6.10. Hope this helps, Rusty.
  21. Do you usually open RAW by importing as a TIFF ?...They should open directly. I'm not at machine right now, but I'll check in a couple of hours. Rusty.
  22. Uhhh....Holy#*&^%Bat*&$#Crazy....What a great image ! Really spectacular work. Thanks for putting it up. Rusty. Ps. Narrow-band...yummy....good.
  23. Hi everybody, Week of long nights working on this... The details..... IC443 captured with an Alta U16M CCD on the LightBuckets 0.37m (14.5") Ritchey-Chrétien (LB-0003). Ha:SII:OIII = 160:160:120 minutes. Bin: 1x1. 1200s subs. Color mapped Ha/SII/OIII as R/G/B. No LUM applied. Processed in CCDStack and PixInsight. RA 06:17:20.00 DEC 22:40:00.00 PA 39.8. A little short on OIII data...as always Couple of bad CCD columns showed up in the last stretch and the color noise is a bit off...grumble, grumble...guess I'm gonna need more data A little Wiki poop on the target.... IC 443 (als
  24. Very nice ! One of the best Sculptors I've seen...not an easy target. Certainly look good on a wall Rusty.
