  1. Here is a bicolor ( Ha + OIII) image of the Crescent nebula. Optics: Equinox 120 Mount: Astrophysics 900 GTO Camera: QSI 690 ( Ha 120’ ; OIII 60’ + Flats ) Post processing: Pixinsight and PS Crescent Nebula Bicolor by Aleksandar Topalov, on Flickr For guiding i use a Lodestar and a 180 mm FL guide scope which gives me an image scale of 9.6 arcsec/pix. My imaging rig gives me 1 “/pix. I know that the guider image scale is way too high. I should probably bring it down to 3-4. Maybe use a barlow? Then i think is Lodestar a good choice for a guiding camera wi
  2. Thanks for the info. I know about the nosepiece. I don’t think there will be a problem to reach focus, CFF has 180 mm backfocus. I reckon that should be enough.
  3. Hi everyone! I plan to buy the baader mark V bino to use with a CFF 132 triplet and C11. I know that a prism, such as the baader T2 prisms, would be the best choice because of the short glass path. The thing is i already have a perfectly good TV 2” everbrite which i love because of the one piece body construction . My question is will i be able to use this combination at all and are there any restrictions to using this combination? Thanks! Aleksandar

    A question for MaximDL users: How much do you delay between exposures for the guider to settle? I've found that with 5 sec I sometimes get elongated stars so I raised it to 15 sec.

    Thanks! I was thinking of adding SII data as well but I actually like the way bicolor images have a sort of natural look.
  6. Hi all! This is a bicolor image of the Elephant trunk taken over two nights. H alpha was taken under urban skies while the OIII data was acquired at a darker location in the countryside. It's actually a work in progress. I have just begun. I will be adding much more data as long as the nights remain clear. The whole imaging process was done in Maxim, while calibration and stacking was done in Pixinsight. Registar was used to align the two channels. Levels, curves, selective color and sharpening was done in PS. Any suggestions would be much appreciated! Ha : 12 x 900" O
  7. I just downloaded it. Its called lightbox extra
  8. Thanks, i’ll try it. I just use Notes as a light source but i guess lightbox is better.
  9. I can put a black T-shirt instead ? i also searched the manual but there is nothing on black images. It is confusing. They should mention it in the manual
  10. You were right Ibbo, I was overexposing it. Last night I tried again with success. For the LUM filter i had to take it down to 0.09 sec in order to get an ADU of 20000. As for the H alpha the exposure had to be 20 sec. Here is an example of the two flats stretched in pixinsight. Does this look ok to you? I mean in terms of acquiring a proper flat image.
  11. Hi! A couple of nights ago I tried taking flats with my Ipad and a white cotton shirt. The outcome was that every image I took turned out completely black no matter what the exposure was ( 1,5, 10 sec). The scope was pointed vertically and the ipad placed on top (white screen was on) with the shirt in between. Just to make sure that everything was ok with the camera ( Atik 4000M ) I took a shot of the sky and everything was fine. Does anyone know what the problem might be?
  12. Hi! Can anyone who has an AP900 mount suggest which case/bag to buy for the RA and Dec. parts separately? It would be great if I didn't have to buy it from the US because shipping is really expensive for heavier stuff. I found one of these on TS but if someone has a better option please tell: https://www.teleskop-express.de/shop/product_info.php/info/p7027_Geoptik-ELEPHANT-Hermetic-Outdoor-Case---687mm-x-528mm-x-366mm.html It doesn't have to be a "super hard case" ,like for airline transport, just something that is strong enough. Thanks!
  13. Or maybe something like this: http://www.teleskop-express.de/shop/product_info.php/info/p9533_TS-Optics-Stabilized-Professional-Power-Supply-6-8-A---13-8-V.html
  14. Hi! Do you think this adapter will work for powering the AP 900? http://www.teleskop-express.de/shop/product_info.php/info/p7948_Baader-mains-adapter-12V-5A--60-Watts----100-240V-primary.html It states on the website that AP 900 requires a minimum of 5 Amp
  15. Hi! I am thinking of going high-end when it comes to diagonals for observing with my C11. I have heard that the Baader-Astrophysics Maxbrite and similar diagonals are superb but pricey!. Are they really worth it? Would they make a big difference in an SCT compared to say these two : http://www.teleskop-express.de/shop/product_info.php/info/p7433_Explore-Scientific-2--Diagonal-Mirror---99--Reflective.html http://www.teleskop-express.de/shop/product_info.php/info/p9290_APM-2--Star-Diagonal-Prism-with-fast-lock-and-ultra-broadband-coating.html Also, I use the Baader Diamond Steeltr
