  1. Add to that.... I want to say, I wish that the camera would get here already so I can test, but as we all know... it's been mostly cloudy since I ordered it and when it arrives, it'll be solid cloud for another 2-3 months... and unlike now.. with no break in the weather what so ever...
  2. Ultimately I'm hoping for a major improvement... There are reports (or opinions) that the 2600MM will "change the game" or "change everything" as stated by a fellow (Astro Backyard) who reviews astro gear... Modding the DSLR is night and day to what it did to sensitivity, especially in HAlpha... and looking at the graph attached, taking the (deeper) cooling, read noise and no bayer filters, gives me hope.... Comparing these graphs... I should capture HAlpha signal 9.6X faster and SII 14X faster with the 2600MM compared to my 40D?? I imagine that DSLR QE would be similar acros
  3. The QE is still higher on this graph than, in theory, on a full spectrum modded DSLR.... (by a factor or 3?) added with the lack of the bayer matrix, this theoretically should cut exposure times by 12X for equivalent subs brightness/photon collection.... but theory and practice hardly ever match up.
  4. Hi Steve... I'll definitely be doing a full comparison... Currently I'm imaging NGC3603... the "Statue of Liberty" nebula in between cloudy & near full moon lit nights. I'm getting more than my fair share of cloud covered nights lately, but it's early in the season and if I get another two or three clear nights in the next 2 weeks than I'll complete this Cooled full spectrum DSLR version just as the 2600MM is due to arrive... than I'll still have enough time do the same image, using the same scope and filters with the new astro cam... this would be my first head to head comparison.
  5. The cooled camera seems to give you very clean images, but, even though a DSLR is rougher, overall, I think that a cooled DSLR is not that much worse... I'm now hoping that with the cleaner subs, I'll be able to capture the same about of photons in much less time due to being the camera being mono and has a QE of 91%... surely no bayer filters and 3X the QE should result in considerably faster captures.
  6. Hello All, Can I pick your brains for info? After a long resistance, I finally bit the bullet and ordered a dedicated astro camera... the ZWO 2600MM-P.... which will be in my hands in around a month... But I have some reservations to whether I just spent a heap of cash for minimal or no improvement in my images. Basically I have been using a full spectrum modded and peltier cooled Canon 40D, cooled using two peltiers on opposite sides of a cold finger, and the cooling works very well.... I have a temperature controller on the system with a thin temperature probe sitting between
  7. Still makes it the first completed image of the season....

    Deep Sky Imaging

    Collection of my Deep Space objects. These images have been take through a 8" SCT or 80mm refractor using a full spectrum modded Canon 40D (as stated in the description of each photo).
  9. Hello all, I managed to bag another object, this time the reflection Nebula M78 in the constellation Orion. I was planning to capture natural color subs than add some HAlpha and OIII narrowband data to emphesize the image details and reveal deeper matter, but after processing the OSC/RGB subs, I decided that adding the narrowband data is not necessary. This image was taken across two nights (juggling clouds), 6th and 11th February, and I managed to capture 3 hours and 18 minutes worth of useful subs (21x60 sec, 19x120 sec, 18x180 and 17 x 300 second subs). The telescope use
  10. First image of the season, and what a way to start a season.... well done.
  11. Excellent image.. something to be proud of...
  12. I'd say start big and spend more than you're comfortable to spend (without bankrupting yourself) and start experimenting, researching as much as you can and basically become obsessed by the hobby until you're coming out with the kind of images that your hoping for.... my theory is that if you spend that much or complex gear, you'll be PUSHED into mastering the hardware because it COST YOU HEAPS, selling it will be a waste of a lot of money and once you have successes, you already have the bigger mount and scope without needing to upgrade.... I started with a 8" SCT at f10.. needless to sa
  13. I was lucky to have seen it too... it was cloudy and rain for at least the week before and during 21st Dec through to evening of 22nd December. The "Clear Outside" app was showing that there was going to be around the 65% cloud cover mark toward the evening so I setup the scope and hoped for the best.. it wasn't until around 20:30 that I started to get breaks in the clouds in the west and luckily was able to catch a glimpse of the conjunction. The view was a little shimmery as the planets were quite low in the western sky but there was some fine(ish) details punching through occasion
  14. Sheeesh... Well done!!!! I remember when I had to clean the corrector plate.. all I was thinking about it.. "Don't drop it!!!".. but the operation was successful.
