  1. thanks buddy, was pleased with the result as I didn't expect it from such limited exposures
  2. Looks really nice and a great reference for me, as I am doing the exact same region FOV on my Rasa8 Great nebulosity there, but I am feeling like the star colours (which are awesome in this region) are lacking. Especially the area between Cone and Dreyers where there is a massive yellow star cluster. But I am nit picking as usual
  3. RASA 8 = On trick pony Cons Can't easily use filters without removing the camera and messing up your rotation / framing Can only use certain size cameras Cables can give bad stars unless you use something like the cable cradle I post above Can't add on reducers etc Can't visual PITA to colimate and very sensitive to collimation / tilt Personally I would not mono shoot due to the filter issue Pros F2 = FAST = Perfect for crappy UK weather with a OSC = nice images quickly Wide FOV 400mm = great for nebulas Relatively cheap (loads on 2nd hand) I have owned many scopes, but the RASA8 is the one I have liked and used the most. The RC10 comes out for galaxy season in the summer.
  4. For giggles, last year I took a single 2x bin single10min sub on the RASA8 (with a lEnhance filter in place) and then processed it as best as I could in PI. 10min FIT sub attached if you want to look and play (this did not have the cable router in place and hence the stars have no spikes, rather cable loops. Also the collimation was off along with 10mins 😃 bad star shapes) Light_IC434_600.0s_Bin2_0002.fit
  5. I have attached a 1xbin 3minute FIT sub of the cone nebula I took last night. The full moon was still low down and got away with it for about 40 mins Light_Debeyers_180.0s_Bin1_20230307-191801_0001.fit
  6. I am using a ZWO 2600 MC Pro OSC which has a deep well depth. Wonder if that helps
  7. Correct, these 2 are the biggest problems. The guiding has nothing to do with it, this was just be advising the previous member who posted his picture, not to bother with F2 and concentrate on the basics, ie get some guiding. The amount of tweaking I had to do to my RASA was ripping my hair out until I was forced to strip it to clean out water increase. This forced me to learn how to collimate the RASA 8 and the OCAL collimator is extremely useful for this.
  8. Not sure, I know that 4 mins is too much and I don't like doing 30s subs, so long time ago plumped for 1xbin 3min subs as a default and then 2x bin in software. To be honest, I not looked too deeply at the sub saturation, just played it by eye. If I am doing something bright, like M42, I will reduce it down to 1 min 1xbin subs and then combine with some 3m 1xbin subs for the outer regions. Not using any filters either
  9. Then stay clear of F2, this will make this more difficult as F2 is very unforgiving. If I were you, I would look at getting some guiding sorted and move from there
  10. I too was amazed that I got this in 90 mins. What you have to remember is the RASA8 is a "proper" astrograph with a cooled dedicated astro camera ZWO 2600 MC Pro. Along with its F2, the image was then resampled in software to effectively give it a 4x on F2 which is amazingly fast. In your image, stars are bloated and I suspect poor guiding and focus, but as you said, you were testing kit out., but either way, it is how it make you feel which is all that counts. I recon you could do MUCH better now you have experience under your belt. Don't bother on borrowing lenses, concentrate on the basics , F2 is much less forgiving and unless you have the basics of guiding and focus, it will be frustrating to say the least.
  11. Really nice and you got a good amount of the IFN there is a large FOV. It really shows the extend of the IFN in this region Love the colours too, not over done which is nice. Did you image the galaxies separately or were they in the same subs ? Very nice.
  12. There is much talk about BlurXTerminator and even the Gaia Spectral Colour Correction in PixInsight and I have been trailing these on some images. Sometimes it is hard to tell if it really works, so here is a comparison of one of my older images taken on my RC10 and 2600 MC Pro last year that I think shows the difference. The original was with my normal workflow and the right image was with these 2 new techniques / tools added to the pre-stretching processes. Hopefully this will help others contemplating using these tools as with these tools I was able to push the processing more and be confident that I had the colours as the science community expects them to be Note - There are a little differences in saturation (that I could push more in the new version), but look at the detail and star sizes that I could never manually achieve without MANY hours of hair pulling
  13. Had a mess around with the options in Stellarium and increased the catalogues and hints shown. Then mix this with a google search of what I can see in Stellarium to see some examples of images and I get what I need. Also worked out what LBN and LDN actually means (bright and dark nebula's) and that helped massively I downloaded Aladin and it seemed way to complicated for me, I could not even find how to put in your location and time (if that is at all possible) Thanks for your help @gorann, it kicked me into actually doing some research
  14. lol, is only Celestron would pay me Thank you and would love to take the scope to a proper dark sky. thank you, was surprised how well it came out for 90 mins Thank you, appreciated Thank you
