Good job in which I'm really intrigued. I have same camera and similar lens. Usually my setting are 75gain with 60" (RGB). Are you using the same? Just out of curiosity, are you going to take also luminance? Just my thoughts, 4 hours is really a lot for color channel why don't invest in L looking for details? Clear sky!

Really nice capture!

Many thanks for let me know about this subject I was ignoring. It is really interesting subject and as far as I can see it should be also interesting to process. I'm really interested in how you take out a so nice blue/Oiii from the master. Would you mind to share some details on your flow? Many thanks and clear sky!

Still a 20 or more days before enjoying the first summer nebula pass over the roof. As many other fellow, this is the time to rearrange, clean, fix and prepare the setup for the nebula season. In the meanwhile, some shot from lost corner in the hard drive, left there, are a good way to spend some time. Awaiting the clear sky.

I should thank you for the chat. Tonight I will check the orthogonality of the focuser as last chance and let you know.

Did you check the 200p with the reego? I've rechecked my SM but it is right in the center under the drawtube of the focuser.

To center the secondary I've used a webcam with a 1,25" noose and the small software mire de collimation (french, Sorry for my maybe wrong spelling) over sharpcap liv image. I maybe have done a not perfect photo with mobile phone....

Here a couple of pictures, on the fly. For both, primary mirror in low side. Not the best focus maybe but can assure the cross of Cheshire is spot in the middle of the primary donut sticker and the secondary is perfect in the middle of the drawtube. The three clips of the PM are visible. What I can't understand is the reego with the black band in th PM direction

Thank you Alan Yes, my bad to post in the wrong (not correct) section. Thank you Clarkey for the support. The reason of willing to use the reego is the capability to check collimation even in the dark without problem. When I bought it, instructed by vendor I made all concentric (drawtube, secondary and primary) with the view of all the reego clear. If I check with Cheshire, the image look like an aim target: everything is concentric but this is not in compliance with the literature: being f5, a little offset have to show the reflection of the secondary a little out of centre. Reverse, if I do the collimation with Cheshire and follow all the rules, I can get a good result compared with all images you can see around on the web (photo though the pinhole of Cheshire). If li check now with reego, I'm unable to see all the reflection of collimator but some part is like cancel(say on the right a kind of black quarter of moon and on the left missing the reego reflection).

Wow Carole. This is an amazing result for a B8 sky. The quantity of O3 is superb

It is an unusual rendition for colours but I don't dislike it. The delicate details of the durst in the between the two nebula is amazing me as well as the shades of the gases. The small scope has a lot of bullet to shot!

Hello to all. Could someone help me? I'm collimating a newton f5 (GSO 150/750) with reego collimator. I'm not exactly clear on the pattern I should see through the small hole in the collimator Can someone upload a picture, for my better understanding? Frankly, I'm getting different result with Cheshire and reego.... Many thanks!

Lately very busy for many reason and unable to save moments for my hobby. I cut one night of decent sky and make a try on a subject not so easy for a short focal lenght. TS80/480 triplet at full FL with ts flattener 1x and asi1600mm. RGB 15x120" each plus L 120x60" at Gain 75. Guiding the eq6-r with phd2 and NINA. All the data processing was done in pixinsight 1.8.8 where the WBPP gave a huge help in managing the task . A test "stealing" the acquisition parameter from other user with similar situation as mine. Even in Bortle 7/8 it is possible to get quite nice result. The rendition of this image, reduced for understandable reason, is not giving a great result. On this, I should think about to get some space maybe on AB. I preferred to keep the background a little light but they s is personal choice. Will be nice to get any suggestions it may help to improve both acquisition and postprocessing. Clear sky to all!

Really excellent result! Could you post a light without crop? Just to understand the dimension of the subject in the frame.

Amazing one! What gain did you set for it? The amount of details is wonderful
