I am looking to step up to a mono camera, and have followed almost all the info out there on the ASI1600. I really like the results I am seeing from the mono cooled version, and find the flexibility of variable gain and the option to shoot shorter exposures to be interesting extra capabilities.I will be moving up from a DSLR and a short stint with the STF-8300C. I am basically waiting for the 7+ position ZWO wheel to come available. I will be shooting using a Stellarvue SVQ100 100mm f/5.8 OTA on a Paramount MyT.
1) It seems like the consensus is that 1.25" filters can work with this camera provided the distance between the filters and sensor is minimized. I am assuming the ZWO branded wheel does that. What are the feelings from users of the ASI1600MM EFW mini ZWO wheel combo - are 1.25" filters OK?
2) I am feeling like I REALLY want to stretch the budget and go with Astrodon NB filters, in a 5nm-3nm-3nm bandwidth setup for Ha, OIII, and SII. That would mean I would have to stay with 1.25" filters in order to not blow my budget. I could go with wider filters or with non-Astrodon filters, but it seems like the best results are from top quality narrow filters. Since I have no mono camera experience to date though I am looking for input on what makes sense. Given what I have already spent on the hobby I am in it for the long haul, I just want to spend my funds wisely.
3) I could also afford Astrodon LRGB filters, but again only if I stay with the 1.25" filter size. The ZWO LRGB filters are only $88 - good grief, can an $88 LRGB filter set compare with a $475 LRGB filter set? What are the tradeoffs? I assume possible focus issues when swapping between ZWO LRGBs and Astrodon NBs. Anything else? There must be a quality difference... Anyone with feedback on the ZWO LRGB filters please chime in.
4) If money becomes critical, I am thinking I can hold off on the SII narrowband filter to begin with, thus saving me $490 if I go with Astrodon. Does that seem like a good compromise?
Thanks bunches for any info.
