  1. Hi, I am considering to buy an ZWO ASI 224mc for planetary imaging. Currently I use an ZWO ASI 120mm-s with Baader RGB filters, Powermate 5X / barlow 2.5X in a Skywatcher 200pds on a Skywatcher NEQ6Pro. I am happy with my results but I am considering the 'upgrade' to the 224 for the following reasons: - clearer lunar zoom photos with the powermate and barlow, using an IR-pass filter to fight the seeing - I would like to try videoastronomy and was told that this is a good camera for this purpose. - I can still do good RGB imaging (with in IR-cut filter) in one shot to also simplify my image processing workflow. My telescope this summer will be located in the Mediterranean and my budget is about 400 pounds (camera and essential filters),. Do my arguments make sense? Does the choice of camera model make sense? or should I stick to my existing setup? Many thanks to all. astroexplorer
  2. I'm thinking of having a go at planetary imaging and would appreciate recommendations for cameras. Thank you
  3. Hi all, I wanted to buy my first narrowband filter. I decided on a 7nm Ha filter. Among the options, there were the Baader 7nm and the Optolong 7nm. I chose the Optolong even though I heard that the colour ones are Astronomik copies. However, I searched some comparisons between the Baader and the Optolong and the Baader seemed to have some halos. I decided on the Optolong. However, I don't have a proper imaging camera and for a while I'll be testing it with the ASI120MM I have. Plans for a larger sensor camera. Yesterday I received the filter and had some tries on M42. My balcony window opens to NEE so M42 is a tough target. I can only point the scope to it on EQ mode only before it reaches 15deg. So I had to switch to AZ mode where a scope can reach almost out of the balcony with the counterweight bar extended. Very good AP setup. Anyway, I attached the ASI120MM to a Tair3s lens, wide open this time at F/4.5 and put them on the AZ-EQ5 in AZ mode. ~40x10s + 70x2s. Gain 70/100. With calibration files. I don't know what to try this evening if it's clear. What do you think about putting the camera on a 135 F/2.8 lens and drizzling 2x? Did anyone of you try drizzling and had a successful result? Clear skies, Alex Edit: I don't know what I've done to have the white frame, I didn't notice it until now. It was probably after combining the 10s image with the 2s one.
